The Nikon D3400 is a 24.2- megapixel DX format DSLR Nikon F-mount camera officially launched by Nikon on August 17, 2016. It is marketed as an entry-level DSLR camera for beginners and experienced DSLR hobbyists. It replaces the D3300 as Nikon's entry level DSLR.
73-490: Nikon offers a body/lens kit combinations that varies from country to country. In most countries the D3400 is available with an AF-P 18-55 mm kit lens that includes Nikon's image stabilization ( Vibration Reduction , VR). In the US there is an unusual two lens kit option offered only with the black body. The 18–55 mm lens has VR but the second lens being a 70–300 mm is the non-VR variant for
146-412: A photographic lens is fixed by its optical construction, and does not change with the format of the sensor that is put behind it. Most DSLRs on the market have nominally APS-C -sized image sensors, smaller than the standard 36 × 24 mm (35 mm) film frame. The result is that the image sensor captures image data from a smaller area than a 35 mm film SLR camera would, effectively cropping out
219-459: A 2× crop factor camera, for instance, a 50 mm lens produces the same field of view as a 100 mm lens used on a 35 mm film camera, and can typically be handheld at 1 ⁄ 100 second. However, image stabilization does not prevent motion blur caused by the movement of the subject or by extreme movements of the camera. Image stabilization is only designed for and capable of reducing blur that results from normal, minute shaking of
292-521: A 35 mm equivalent focal length of 800 millimeters) and a little more than ten seconds for wide angle shots (with a 35 mm equivalent focal length of 24 millimeters), if the movement of the Earth is not taken into consideration by the image stabilization process. In 2015, the Sony E camera system also allowed combining image stabilization systems of lenses and camera bodies, but without synchronizing
365-452: A 35 mm format full-frame camera , but on a camera with a 1.6 crop factor, an image made with the same lens will have the same field of view that a full-frame camera would make with a ~45 mm lens (28 × 1.6 = 44.8). This narrowing of the FOV is a disadvantage to photographers when a wide FOV is desired. Ultra-wide lens designs become merely wide; wide-angle lenses become ' normal '. However,
438-429: A 9 mm sensor diagonal has a crop factor of almost 5 relative to the 43.3 mm diagonal of 35 mm film. Therefore, these cameras are equipped with lenses that are about one-fifth of the focal lengths that would be typical on a 35 mm point-and-shoot film camera. In most cases, manufacturers label their cameras and lenses with their actual focal lengths, but in some cases they have chosen to instead multiply by
511-439: A crop factor of about 6 ("1/2.5-inch" format). The crop factor is sometimes referred to as "magnification factor", "focal length factor" or "focal length multiplier". This usage reflects the observation that lenses of a given focal length seem to produce greater magnification on crop-factor cameras than they do on full-frame cameras. This is an advantage in, for example, bird photography, where photographers often strive to get
584-423: A fixed focal-plane illuminance and exposure time , larger image sensors capture more photons and hence produce images with less image noise and greater dynamic range than smaller sensors. Due to the statistics of photon shot noise , the desirable properties of signal-to-noise ratio (SNR) and sensor unity gain both scale with the square root of pixel area. Since crop factor is inversely proportional to
657-457: A given shutter speed for a sharp image is reduced by the crop factor. The old rule of thumb that shutter speed should be at least equal to focal length (in millimetres) for hand-holding will work equivalently if the actual focal length is multiplied by the FLM first before applying the rule. Many photographic lenses produce a more superior image in the center of the frame than around the edges. When using
730-415: A high-sensitivity mode that uses a short exposure time—producing pictures with less motion blur, but more noise. It reduces blur when photographing something that is moving, as well as from camera shake. Others now also use digital signal processing (DSP) to reduce blur in stills, for example by sub-dividing the exposure into several shorter exposures in rapid succession, discarding blurred ones, re-aligning
803-472: A large display such as a television set or computer monitor . Different companies have different names for the OIS technology, for example: Most high-end smartphones as of late 2014 use optical image stabilization for photos and videos. In Nikon and Canon's implementation , it works by using a floating lens element that is moved orthogonally to the optical axis of the lens using electromagnets. Vibration

#1732891313006876-511: A larger amplitude and timeframe (typically body and hand movement when standing on a stationary or slowly moving platform while using slower shutter speeds). Most manufacturers suggest that the IS feature of a lens be turned off when the lens is mounted on a tripod as it can cause erratic results and is generally unnecessary. Many modern image stabilization lenses (notably Canon's more recent IS lenses) are able to auto-detect that they are tripod-mounted (as
949-424: A lens designed to expose a 35 mm film frame with a smaller-format sensor, only the central "sweet spot" of the image is used; a lens that is unacceptably soft or dark around the edges can give better results on a smaller sensor. However, since the image projected onto the sensor must be magnified more to make a print using a smaller sensor, lenses used on smaller formats must deliver a higher-resolution image to
1022-495: A lens due to hand-held shooting. Some lenses and camera bodies include a secondary panning mode or a more aggressive 'active mode', both described in greater detail below under optical image stabilization . Astrophotography makes much use of long-exposure photography , which requires the camera to be fixed in place. However, fastening it to the Earth is not enough, since the Earth rotates . The Pentax K-5 and K-r, when equipped with
1095-431: A lens with a 50 mm focal length on an imaging area with a crop factor of 1.6 with respect to the reference format (usually 35 mm) will yield the same field of view that a lens with an 80 mm focal length will yield on the reference format. If it is desired to capture an image with the same field of view and image quality but different cameras, the aperture and ISO settings also need to be adjusted with respect to
1168-450: A moving vehicle, such as a car or boat, which is supposed to correct for larger shakes than the "normal" mode. However, active mode used for normal shooting can produce poorer results than normal mode. This is because active mode is optimized for reducing higher angular velocity movements (typically when shooting from a heavily moving platform using faster shutter speeds), where normal mode tries to reduce lower angular velocity movements over
1241-508: A remote stabilized head that is used to stabilize moving TV cameras that are broadcasting live is the Newton stabilized head. Another technique for stabilizing a video or motion picture camera body is the Steadicam system, which isolates the camera from the operator's body using a harness and a camera boom with a counterweight. A camera stabilizer is any device or object that externally stabilizes
1314-423: A result of extremely low vibration readings) and disable IS automatically to prevent this and any consequent image quality reduction. The system also draws battery power, so deactivating it when not needed extends the battery charge. A disadvantage of lens-based image stabilization is cost. Each lens requires its own image stabilization system. Also, not every lens is available in an image-stabilized version. This
1387-399: A smaller image circle than lenses that were designed for the full-frame 35 mm format. Nevertheless, the crop factor or FLM of a camera has the same effect on the relationship between field of view and focal length with these lenses as with any other lens, even though the projected image is not as severely "cropped". In this sense, the term crop factor sometimes has confusing implications;
1460-453: A smaller image circle, the lenses can be optimized to use less glass and are sometimes physically smaller and lighter than those designed for full-frame cameras. Lenses designed for the smaller digital formats include Canon EF-S and EF-M lenses, Nikon DX lenses, Olympus Four Thirds System lenses, Sigma DC lenses, Tamron Di-II lenses, Pentax DA lenses, Fujifilm XF and XC lenses, and Sony Alpha (SAL) DT & E lenses. Such lenses usually project
1533-524: A standard output size. That is, the magnification, as usually defined from subject to focal plane, is unchanged, but the system magnification from subject to final output is increased. When a lens designed for 35 mm format is used on a smaller-format DSLR, besides the obvious reduction in field of view, there may be secondary effects on depth of field , perspective , camera-motion blur, and other photographic parameters. The depth of field may change, depending on what conditions are compared. Shooting from

1679-536: Is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure . Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch ) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ( roll ). It is mainly used in high-end image-stabilized binoculars , still and video cameras, astronomical telescopes , and also smartphones . With still cameras , camera shake
1752-579: Is a particular problem at slow shutter speeds or with long focal length lenses ( telephoto or zoom ). With video cameras , camera shake causes visible frame-to-frame jitter in the recorded video. In astronomy, the problem of lens shake is added to variation in the atmosphere , which changes the apparent positions of objects over time. In photography, image stabilization can facilitate shutter speeds 2 to 5.5 stops slower (exposures 4 to 22 + 1 ⁄ 2 times longer), and even slower effective speeds have been reported. A rule of thumb to determine
1825-434: Is a property that depends only on viewpoint (camera position). But if moving a lens to a smaller-format camera causes a photographer to move further from the subject, then the perspective will be affected. The extra amount of enlargement required with smaller-format cameras increases the blur due to defocus, and also increases the blur due to camera motion (shake). As a result, the focal length that can be reliably hand-held at
1898-418: Is detected using two piezoelectric angular velocity sensors (often called gyroscopic sensors), one to detect horizontal movement and the other to detect vertical movement. As a result, this kind of image stabilizer corrects only for pitch and yaw axis rotations, and cannot correct for rotation around the optical axis. Some lenses have a secondary mode that counteracts vertical-only camera shake. This mode
1971-484: Is in the upcoming gigapixel telescope Pan-STARRS being constructed in Hawaii. A technique that requires no additional capabilities of any camera body–lens combination consists of stabilizing the entire camera body externally rather than using an internal method. This is achieved by attaching a gyroscope to the camera body, usually using the camera's built-in tripod mount. This lets the external gyro (gimbal) stabilize
2044-431: Is no larger image to work with the filter either crops the image down to hide the motion of the frame or attempts to recreate the lost image at the edge through spatial or temporal extrapolation . Online services, including YouTube , are also beginning to provide ' video stabilization as a post-processing step after content is uploaded. This has the disadvantage of not having access to the realtime gyroscopic data, but
2117-401: Is not an issue for Mirrorless interchangeable-lens camera systems, because the sensor output to the screen or electronic viewfinder is stabilized. The sensor capturing the image can be moved in such a way as to counteract the motion of the camera, a technology often referred to as mechanical image stabilization. When the camera rotates, causing angular error, gyroscopes encode information to
2190-493: Is often the case for fast primes and wide-angle lenses. However, the fastest lens with image stabilisation is the Nocticron with a speed of f /1.2. While the most obvious advantage for image stabilization lies with longer focal lengths, even normal and wide-angle lenses benefit from it in low-light applications. Lens-based stabilization also has advantages over in-body stabilization. In low-light or low-contrast situations,
2263-460: Is that the camera can automatically correct for tilted horizons in the optical domain, provided it is equipped with an electronic spirit level, such as the Pentax K-7/K-5 cameras. One of the primary disadvantages of moving the image sensor itself is that the image projected to the viewfinder is not stabilized. Similarly, the image projected to a phase-detection autofocus system that is not part of

2336-411: Is the ratio of the dimensions of a camera 's imaging area compared to a reference format; most often, this term is applied to digital cameras , relative to 35 mm film format as a reference. In the case of digital cameras, the imaging device would be a digital image sensor . The most commonly used definition of crop factor is the ratio of a 35 mm frame's diagonal (43.3 mm) to the diagonal of
2409-456: Is used in some video cameras. This technique shifts the cropped area read out from the image sensor for each frame to counteract the motion. This requires the resolution of the image sensor to exceed the resolution of the recorded video, and it slightly reduces the field of view because the area on the image sensor outside the visible frame acts as a buffer against hand movements. This technique reduces distracting vibrations from videos by smoothing
2482-417: Is useful when using a panning technique. Some such lenses activate it automatically; others use a switch on the lens. To compensate for camera shake in shooting video while walking, Panasonic introduced Power Hybrid OIS+ with five-axis correction: axis rotation, horizontal rotation, vertical rotation, and horizontal and vertical motion. Some Nikon VR-enabled lenses offer an "active" mode for shooting from
2555-561: The Panasonic Lumix DC-GH5 , Panasonic, who formerly only equipped lens-based stabilization in its interchangeable lens camera system (of the Micro Four Thirds standard), introduced sensor-shift stabilization that works in concert with the existing lens-based system ("Dual IS"). In the meantime (2016), Olympus also offered two lenses with image stabilization that can be synchronized with the in-built image stabilization system of
2628-467: The Sony α line and Shake Reduction (SR) in the Pentax K-series and Q series cameras, which relies on a very precise angular rate sensor to detect camera motion. Olympus introduced image stabilization with their E-510 D-SLR body, employing a system built around their Supersonic Wave Drive. Other manufacturers use digital signal processors (DSP) to analyze the image on the fly and then move
2701-404: The 2-to-4.5-stops slower shutter speeds allowed by IS, an image taken at 1 ⁄ 125 second speed with an ordinary lens could be taken at 1 ⁄ 15 or 1 ⁄ 8 second with an IS-equipped lens and produce almost the same quality. The sharpness obtainable at a given speed can increase dramatically. When calculating the effective focal length, it is important to take into account
2774-405: The 35 mm film format, but often utilized existing 35 mm film format SLR lens mounts. Using an FLM of 1.5, for example, a photographer might say that a 50 mm lens on a DSLR "acts like" its focal length has been multiplied by 1.5, which means that it has the same field of view as a 75 mm lens on the film camera that they are more familiar with. Of course, the actual focal length of
2847-470: The O-GPS1 GPS accessory for position data, can use their sensor-shift capability to reduce the resulting star trails . Stabilization can be applied in the lens, or in the camera body. Each method has distinctive advantages and disadvantages. An optical image stabilizer ( OIS , IS , or OS ) is a mechanism used in still or video cameras that stabilizes the recorded image by varying the optical path to
2920-400: The actuator that moves the sensor. The sensor is moved to maintain the projection of the image onto the image plane, which is a function of the focal length of the lens being used. Modern cameras can automatically acquire focal length information from modern lenses made for that camera. Minolta and Konica Minolta used a technique called Anti-Shake (AS) now marketed as SteadyShot (SS) in
2993-402: The added advantage of working with all lenses. Optical image stabilization prolongs the shutter speed possible for handheld photography by reducing the likelihood of blurring the image from shake during the same exposure time. For handheld video recording , regardless of lighting conditions, optical image stabilization compensates for minor shakes whose appearance magnifies when watched on

3066-447: The advantage of more computing power and the ability to analyze images both before and after a particular frame. Used in astronomy, an orthogonal transfer CCD (OTCCD) actually shifts the image within the CCD itself while the image is being captured, based on analysis of the apparent motion of bright stars. This is a rare example of digital stabilization for still pictures. An example of this
3139-404: The alternative term "focal length multiplier" is sometimes used for this reason. Smaller, non-DSLR, consumer cameras, typically referred to as point-and-shoot cameras, can also be characterized as having a crop factor or FLM relative to 35 mm format, even though they do not use interchangeable lenses or lenses designed for a different format. For example, the so-called "1/1.8-inch" format with
3212-435: The autofocus system (which has no stabilized sensors) is able to work more accurately when the image coming from the lens is already stabilized. In cameras with optical viewfinders, the image seen by the photographer through the stabilized lens (as opposed to in-body stabilization) reveals more detail because of its stability, and it also makes correct framing easier. This is especially the case with longer telephoto lenses. This
3285-536: The camera can stabilize older lenses, and lenses from other makers. This isn't viable with zoom lenses, because their focal length is variable. Some adapters communicate focal length information from the maker of one lens to the body of another maker. Some lenses that do not report their focal length can be retrofitted with a chip which reports a pre-programmed focal-length to the camera body. Sometimes, none of these techniques work, and image-stabilization cannot be used with such lenses. In-body image stabilization requires
3358-452: The camera to take advantage of the improvements, which is typically far less expensive than replacing all existing lenses if relying on lens-based image stabilization. Some sensor-based image stabilization implementations are capable of correcting camera roll rotation, a motion that is easily excited by pressing the shutter button. No lens-based system can address this potential source of image blur. A by-product of available "roll" compensation
3431-479: The camera, and is typically used in photography from a moving vehicle, when a lens or camera offering another type of image stabilization is not available. A common way to stabilize moving cameras after approx. year 2015 is by using a camera stabilizer such as a stabilized remote camera head. The camera and lens are mounted in a remote controlled camera holder which is then mounted on anything that moves, such as rail systems, cables, cars or helicopters. An example of
3504-399: The camera. This can refer to a Steadicam , a tripod , the camera operator's hand, or a combination of these. In close-up photography, using rotation sensors to compensate for changes in pointing direction becomes insufficient. Moving, rather than tilting, the camera up/down or left/right by a fraction of a millimeter becomes noticeable if you are trying to resolve millimeter-size details on
3577-496: The crop factor (focal length multiplier) and label the 35 mm equivalent focal length . Reviewers also sometimes use the 35 mm-equivalent focal length as a way to characterize the field of view of a range of cameras in common terms. For example, the Canon Powershot SD600 lens is labeled with its actual focal length range of 5.8–17.4 mm. But it is sometimes described in reviews as a 35–105 mm lens, since it has
3650-421: The crop factor can be an advantage to photographers when a narrow FOV is desired. It allows photographers with long-focal-length lenses to fill the frame more easily when the subject is far away. A 300 mm lens on a camera with a 1.6 crop factor delivers images with the same FOV that a 35 mm film format camera would require a 480 mm long focus lens to capture. For a given exposure , for example for
3723-402: The crop factor. The crop factor is sometimes used to compare the field of view and image quality of different cameras with the same lens. The crop factor is sometimes referred to as the focal length multiplier ("Film") since multiplying a lens focal length by the crop factor gives the focal length of a lens that would yield the same field of view if used on the reference format. For example,
SECTION 50
#17328913130063796-483: The crop factor. The focal length of the lens does not change by using a smaller imaging area; the field of view is correspondingly smaller because a smaller area of the image circle cast by the lens is used by the smaller imaging area. The terms crop factor and focal length multiplier were coined to help 35 mm film format SLR photographers understand how their existing ranges of lenses would perform on newly introduced DSLR cameras which had sensors smaller than
3869-413: The edges of the image that would be captured by the 36 mm × 24 mm 'full-size' film frame. Because of this crop, the effective field of view (FOV) is reduced by a factor proportional to the ratio between the smaller sensor size and the 35 mm film format (reference) size. For most DSLR cameras, this factor is 1.3–2.0×. For example, a 28 mm lens delivers a moderately wide-angle FOV on
3942-468: The image by moving the eyes . When a rotation of the head is detected, an inhibitory signal is sent to the extraocular muscles on one side and an excitatory signal to the muscles on the other side. The result is a compensatory movement of the eyes. Typically eye movements lag the head movements by less than 10 ms. Crop factor In digital photography , the crop factor , format factor , or focal length multiplier of an image sensor format
4015-412: The image format a camera uses. For example, many digital SLR cameras use an image sensor that is 2 ⁄ 3 , 5 ⁄ 8 , or 1 ⁄ 2 the size of a 35 mm film frame. This means that the 35 mm frame is 1.5, 1.6, or 2 times the size of the digital sensor. The latter values are referred to as the crop factor , field-of-view crop factor, focal-length multiplier, or format factor. On
4088-408: The image sensor in question; that is, CF = diag 35 mm / diag sensor {\displaystyle {\text{CF}}={\text{diag}}_{35{\text{mm}}}/{\text{diag}}_{\text{sensor}}} . Given the same 3:2 aspect ratio as 35mm's 36 mm × 24 mm area, this is equivalent to the ratio of heights or ratio of widths; the ratio of sensor areas is the square of
4161-402: The image sensor, if used, is not stabilized. This is not an issue on cameras that use an electronic viewfinder (EVF), since the image projected on that viewfinder is taken from the image sensor itself. Some, but not all, camera-bodies capable of in-body stabilization can be pre-set manually to a given focal length. Their stabilization system corrects as if that focal length lens is attached, so
4234-417: The image sensors of Olympus' Micro Four Thirds cameras ("Sync IS"). With this technology a gain of 6.5 f -stops can be achieved without blurred images. This is limited by the rotational movement of the surface of the Earth, that fools the accelerometers of the camera. Therefore, depending on the angle of view, the maximum exposure time should not exceed 1 ⁄ 3 second for long telephoto shots (with
4307-407: The lens to have a larger output image circle because the sensor is moved during exposure and thus uses a larger part of the image. Compared to lens movements in optical image stabilization systems the sensor movements are quite large, so the effectiveness is limited by the maximum range of sensor movement, where a typical modern optically-stabilized lens has greater freedom. Both the speed and range of
4380-403: The maximum "reach". A camera with a smaller sensor can be preferable to using a teleconverter , because the latter affects the f-number of the lens, and can therefore degrade the performance of the autofocus. A given lens casts the same image no matter what camera it is attached to. The extra "magnification" occurs when the image is enlarged more to produce output (print or screen) that matches
4453-508: The more recent higher end R3 , R5 , R6 (and its MkII version) and the APS-C R7 . However, the full frame R8 and APS-C R10 do not have IBIS. All of Nikon's full-frame Z-mount bodies—the Z 6 , Z 7 , the Mark II versions of both, the Z 8 and Z 9 , have IBIS. However, its APS-C Z 50 lacks IBIS.

#17328913130064526-429: The object. Linear accelerometers in the camera, coupled with information such as the lens focal length and focused distance, can feed a secondary correction into the drive that moves the sensor or optics, to compensate for linear as well as rotational shake. In many animals, including human beings, the inner ear functions as the biological analogue of an accelerometer in camera image stabilization systems, to stabilize
4599-408: The required sensor movement increase with the focal length of the lens being used, making sensor-shift technology less suited for very long telephoto lenses, especially when using slower shutter speeds, because the available motion range of the sensor quickly becomes insufficient to cope with the increasing image displacement. In September 2023, Nikon has announced the release of Nikon Z f , which has
4672-450: The same degrees of freedom . In this case, only the independent compensation degrees of the in-built image sensor stabilization are activated to support lens stabilisation. Canon and Nikon now have full-frame mirrorless bodies that have IBIS and also support each company's lens-based stabilization. Canon's first two such bodies, the EOS R and RP , do not have IBIS, but the feature was added for
4745-421: The same position, with the same lens and same f-number as a non-cropped (full-frame) 35 mm camera, but enlarging the image to a given reference size, will yield a reduced depth of field. On the other hand, using a different lens with the same field of view as the non-cropped camera (matching the 35 mm-equivalent focal length), at same f-number, the smaller camera's depth of field is greater. Perspective
4818-502: The sensor appropriately. Sensor shifting is also used in some cameras by Fujifilm, Samsung, Casio Exilim and Ricoh Caplio. The advantage with moving the image sensor , instead of the lens, is that the image can be stabilized even on lenses made without stabilization. This may allow the stabilization to work with many otherwise-unstabilized lenses, and reduces the weight and complexity of the lenses. Further, when sensor-based image stabilization technology improves, it requires replacing only
4891-451: The sensor. This technology is implemented in the lens itself, as distinct from in-body image stabilization ( IBIS ), which operates by moving the sensor as the final element in the optical path. The key element of all optical stabilization systems is that they stabilize the image projected on the sensor before the sensor converts the image into digital information. IBIS can have up to 5 axis of movement: X, Y, Roll, Yaw, and Pitch. IBIS has
4964-399: The sharpest sub-exposures and adding them together, and using the gyroscope to detect the best time to take each frame. Many video non-linear editing systems use stabilization filters that can correct a non-stabilized image by tracking the movement of pixels in the image and correcting the image by moving the frame. The process is similar to digital image stabilization but since there
5037-409: The slowest shutter speed possible for hand-holding without noticeable blur due to camera shake is to take the reciprocal of the 35 mm equivalent focal length of the lens, also known as the "1/mm rule" . For example, at a focal length of 125 mm on a 35 mm camera, vibration or camera shake could affect sharpness if the shutter speed is slower than 1 ⁄ 125 second. As a result of
5110-508: The smaller crop factor and the higher signal-to-noise ratio. Most SLR camera and lens manufacturers have addressed the concerns of wide-angle lens users by designing lenses with shorter focal lengths, optimized for the DSLR formats. In most cases, these lenses are designed to cast a smaller image circle that would not cover a 24×36 mm frame, but is large enough to cover the smaller 16×24 mm (or smaller) sensor in most DSLRs. Because they cast
5183-436: The square root of sensor area (to within a small aspect ratio-dependent factor), it is useful for estimating image sensor performance. For example, if two different-sized image sensors have the same aspect ratio and a resolution of 10 megapixels , and are made using similar technology, the larger sensor will have better signal-to-noise ratio by a factor equal to the ratio of the two sensors' crop factors. The larger sensor has
5256-459: The transition from one frame to another. This technique can not do anything about existing motion blur, which may result in an image seemingly losing focus as motion is compensated due to movement during the exposure times of individual frames. This effect is more visible in darker sceneries due to prolonged exposure times per frame. Some still camera manufacturers marketed their cameras as having digital image stabilization when they really only had
5329-534: The world’s first Focus-Point VR technology that centers the axis of sensor shift image stabilization at the autofocus point, rather than at the center of the sensor like the conventional sensor shift image stabilization system. This allows for vibration reduction at the focused point rather than just in the center of the image. Starting with the Panasonic Lumix DMC-GX8 , announced in July 2015, and subsequently in
