#17328695462331272-590: A photographer purchased one of these lenses, that lens included a leaf shutter in its lens mount. Because leaf shutters synchronized electronic flash at all shutter speeds especially at fast shutter speeds of 1 ⁄ 500 of a second or faster, cameras using leaf shutters were more desirable to studio photographers who used sophisticated studio electronic flash systems. Some manufacturers of medium-format 120 film SLR cameras also made leaf-shutter lenses for their focal-plane-shutter models. Rollei made at least two such lenses for their Rolleiflex SL-66 medium format which
1378-529: A potential shift in attitudes to reuse and repair. With turnover of small household appliances high and costs relatively low, many consumers will throw unwanted electric goods in the normal dustbin, meaning that items of potentially high reuse or recycling value go to landfills. While more oversized items such as washing machines are usually collected, it has been estimated that the 160,000 tonnes of EEE in regular waste collections were worth £220 million. And 23% of EEE taken to Household Waste Recycling Centres

Vertical shutters became very common in the 1980s (though Konica , Mamiya , and Copal first pioneered their use in the 1950s and 1960s, and are almost exclusively used for new cameras. Nikon used Copal-made vertical plane shutters in their Nikomat/Nikkormat -range, enabling x-sync speeds from 1 ⁄ 30 to 1 ⁄ 125 while
3286-512: Is rated for 200,000 shutter cycles and the Nikon D3 is rated for 300,000 with its exotic carbon fiber/kevlar shutter. Because many SLRs have interchangeable lenses, there is a tendency for dust, sand and dirt to get into the main body of the camera through the mirror box when the lens is removed, thus dirtying or even jamming the mirror movement mechanism or the shutter curtain mechanism itself. In addition, these particles can also jam or otherwise hinder

7632-586: The focusing feature of a lens if they enter into the focusing helicoid. The problem of sensor cleaning has been somewhat reduced in DSLRs as some cameras have a built-in sensor cleaning unit. The price of SLRs in general also tends to be somewhat higher than that of other types of cameras, owing to their internal complexity. This is compounded by the expense of additional components, such as flashes or lenses. The initial investment in equipment can be prohibitive enough to keep some casual photographers away from SLRs, although

An electronics district is an area of commerce with a high density of retail stores that sell consumer electronics. Consumer electronic service can refer to the maintenance of said products. When consumer electronics have malfunctions, they may sometimes be repaired. In 2013, in Pittsburgh, Pennsylvania,
7844-424: The increased popularity in listening to sound from analog audio devices, such as phonographs , as opposed to digital sound, has sparked a noticeable increase of business for the electronic repair industry there. A mobile phone , cellular phone, cell phone, cellphone, handphone, or hand phone, sometimes shortened to simply mobile, cell or just phone, is a portable telephone that can make and receive calls over
7950-523: The industry to develop a number of technologies, such as WirelessHD or ITU-T G.hn , which are optimized for distribution of HD content between consumer electronic devices in a home. The consumer electronics industry faces consumers with unpredictable tastes on the demand side, supplier-related delays or disruptions on the supply side, and production challenges occurring in the process. The high rate of technology evolution or revolution requires large investments without any guarantee of profitable returns. As
8056-548: The industry, attracting many consumer electronics companies such as Apple Inc. An electronic component is any essential discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form, and are not to be confused with electrical elements , conceptual abstractions representing idealized electronic components. Consumer electronics such as personal computers use various types of software. Embedded software
8162-598: The internet and digital technologies. The consumer electronics industry has primarily merged with the software industry in what is increasingly referred to as the consumerization of information technology . One overriding characteristic of consumer electronic products is the trend of ever-falling prices. This is driven by gains in manufacturing efficiency and automation , lower labor costs as manufacturing has moved to lower-wage countries, and improvements in semiconductor design. Semiconductor components benefit from Moore's law , an observed principle which states that, for
8268-405: The market for used SLRs has become larger particularly as photographers migrate to digital systems. The digital single-lens reflex camera has largely replaced the film SLR for its convenience, sales, and popularity at the start of the 21st century. These cameras were the marketing favorite among advanced amateur and professional photographers through the first two decades of
8374-508: The mass market, Leica's PLOOT reflex housing along with a 200 mm f4.5 lens paired to a 35 mm rangefinder camera body, debuted in 1935. The Soviet Спорт (“Sport”), also a 24 mm by 36 mm image size, was prototyped in 1934 and went to market in 1937. K. Nüchterlein's Kine Exakta (Germany, 1936) was the first integrated 35 mm SLR to enter the market. Additional Exakta models, all with waist-level finders, were produced up to and during World War II . Another ancestor of
8480-456: The midprice range of $ 70–$ 300, along with certain camera accessories. New Vivitar-branded products such as digital photo frames are also planned, as well as potential licensing opportunities. In January 2009 Sakar introduced three new Vivitar-branded cameras and a digital SLR lens series. The products are Sakar's first Vivitar-branded items since acquiring the brand. In addition to other electronics products, in 2013 they announced and then shipped
8586-404: The mirror box and pentaprism/pentamirror. The mirror box also prevents lenses with deeply recessed rear elements from being mounted close to the film or sensor unless the camera has a mirror lockup feature; this means that simple designs for wide angle lenses cannot be used. Instead, larger and more complex retrofocus designs are required. The SLR mirror 'blacks-out' the viewfinder image during
8692-401: The mirror moves upwards from its resting position in the direction of the arrow, the focal plane shutter opens, and the image is projected onto the film or sensor in exactly the same manner as on the focusing screen. This feature distinguishes SLRs from other cameras as the photographer sees the image composed exactly as it will be captured on the film or sensor . Most 35 mm SLRs use
8798-597: The modern SLR camera was the Swiss-made Alpa , which was innovative, and influenced the later Japanese cameras. The first eye-level SLR viewfinder was patented in Hungary on August 23, 1943, by Jenő Dulovits, who then designed the first 35 mm camera with one, the Duflex , which used a system of mirrors to provide a laterally correct, upright image in the eye-level viewfinder. The Duflex, which went into serial production in 1948,
8904-523: The only choice for focal plane shutters at that time was 1 ⁄ 60 . Later, Nikon again pioneered the use of titanium for vertical shutters, using a special honeycomb pattern on the blades to reduce their weight and achieve world-record speeds in 1982 of 1 ⁄ 4000 second for non-sync shooting, and 1 ⁄ 250 with x-sync. Nowadays most such shutters are manufactured from cheaper aluminium (though some high-end cameras use materials such as carbon-fibre and Kevlar ). Another shutter system
9010-423: The photographer with considerably more control (i.e., how the image is viewed and framed) than would be the case with a view camera. In addition, some SLR lenses are manufactured with extremely long focal lengths, allowing a photographer to be a considerable distance away from the subject and yet still expose a sharp, focused image. This is particularly useful if the subject includes dangerous animals (e.g., wildlife);
9116-403: The produced electronic waste from developed countries is exported, and handled by the informal sector in countries like India, despite the fact that exporting electronic waste to them is illegal. Strong informal sector can be a problem for the safe and clean recycling. E-waste policy has gone through various incarnations since the 1970s, with emphases changing as the decades passed. More weight
9222-573: The raw materials. The energy consumption of consumer electronics and their environmental impact, either from their production processes or the disposal of the devices, is increasing steadily. EIA estimates that electronic devices and gadgets account for about 10%–15% of the energy use in American homes – largely because of their number; the average house has dozens of electronic devices. The energy consumption of consumer electronics increases – in America and Europe – to about 50% of household consumption if
9328-452: The sale of the Vivitar brand name and intellectual property to privately held consumer electronics maker Sakar International, based in Edison, New Jersey . Sakar did not purchase Vivitar's equipment, facilities or accounts receivable . Terms of the deal were not disclosed. In August 2008, Sakar announced plans to position Vivitar as a brand for its current mass retail digital cameras in
9434-467: The sales department, while John Best ran the operations side of the company. Ponder and Best first imported German-made photo equipment. After World War II , the partnership began to import cameras and photographic equipment from Japan. They were instrumental in the introduction of many brands into the American market, including Mamiya /Sekor 35mm cameras, OM-System 35mm equipment, Kobena 8mm movie cameras, Sankyo/Komura wide-angle/telephoto adapter lenses and
9540-521: The same, and after having bought Konica Minolta's camera division in 2006. Sony continues using the Minolta AF lens mount in their DSLRs, including cameras built around a semi-transparent fixed mirror . Samsung builds DSLRs based on the Pentax lens mount. Olympus , on the other hand, chose to create a new digital-only Four Thirds System SLR standard, adopted later by Panasonic and Leica. Contax came out with
9646-417: The side ( rangefinder ). Because the viewfinder and the film lens cannot share the same optical path, the viewing lens is aimed to intersect with the film lens at a fixed point somewhere in front of the camera. This is not problematic for pictures taken at a middle or longer distance, but parallax causes framing errors in close-up shots. Moreover, it is not easy to focus the lens of a fast reflex camera when it
9752-442: The sound so that it could be played through a loudspeaker . Television was soon invented but remained insignificant in the consumer market until the 1950s. The first working transistor , a point-contact transistor , was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, which led to significant research in the field of solid-state semiconductors in the early-1950s. The invention and development of
9858-405: The start of the 21st century. A cross-section ( or 'side-view') of the optical components of a typical SLR camera shows how the light passes through the lens assembly, is reflected by the mirror placed at a 45-degree angle, and is projected on the matte focusing screen . Via a condensing lens and internal reflections in the roof pentaprism the image appears in the eyepiece. When an image is taken,
9964-881: The stigma for some of owning second-hand goods. But the benefits of reuse could allow lower-income households access to previously unaffordable technology while helping the environment at the same time. Desktop monitors and laptops produce major physical health concerns for humans when bodies are forced into unhealthy and uncomfortable positions to see the screen better. From this, neck and back pains and problems increase, commonly referred to as repetitive strain injuries . Using electronics before going to bed makes it difficult for people to fall asleep, hurting human health. Sleeping less prevents people from performing to their full potential physically and mentally and can also "increase rates of obesity and diabetes", which are "long-term health consequences". Obesity and diabetes are more commonly seen in students and in youth because they tend to be
10070-552: The subject prefers anonymity to being photographed; or else, the photographer's presence is unwanted (e.g., celebrity photography or surveillance photography). Practically all SLR and DSLR camera bodies can also be attached to telescopes and microscopes via an adapter tube to further enhance their imaging capabilities. In most cases, single-lens reflex cameras cannot be made as small or as light as other camera designs—such as rangefinder cameras , autofocus compact cameras and digital cameras with electronic viewfinders (EVF)—owing to
10176-418: The term is redefined to include home appliances such as refrigerators , dryers , clothes washers and dishwashers . Standby power – used by consumer electronics and appliances while they are turned off – accounts for 5–10% of total household energy consumption, costing $ 100 annually to the average household in the United States. A study by United States Department of Energy 's Berkeley Lab found that
10282-435: The top models, whereas the best rangefinder cameras adopted such features later. Many of the advantages of SLR cameras derive from viewing and focusing the image through the attached lens. Most other types of cameras do not have this function; subjects are seen through a viewfinder that is near the lens, making the photographer's view different from that of the lens. SLR cameras provide photographers with precision; they provide
10388-432: The viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured. Until the development of SLR, all cameras with viewfinders had two optical light paths: one through the lens to the film, and another positioned above ( TLR or twin-lens reflex ) or to
10494-596: The world's largest professional society, has many initiatives to advance the state of the art of consumer electronics. IEEE has a dedicated society of thousands of professionals to promote CE, called the Consumer Electronics Society (CESoc). IEEE has multiple periodicals and international conferences to promote CE and encourage collaborative research and development in CE. The flagship conference of CESoc, called IEEE International Conference on Consumer Electronics (ICCE),
10600-438: The world's leading consumer electronics companies about their energy and resource consumption and the use of chemicals. Electronic devices use thousands rare metals and rare earth elements (40 on average for a smartphone ), these material are extracted and refined using water and energy-intensive processes. These metals are also used in the renewable energy industry meaning that consumer electronics are directly competing for
10706-527: Was a focal-plane shutter SLR. Rollei later switched to a camera system of leaf-shutter design (e.g., the 6006 and 6008 reflexes) and their current medium-format SLRs are now all of the between-the-lens shutter design. Since the technology became widespread in the 1970s, SLRs have become the main photographic instrument used by dedicated amateur photographers and professionals. Some photographers of static subjects (such as architecture, landscape, and some commercial subjects), however, prefer view cameras because of
10812-530: Was also the world's first SLR with an instant-return (a.k.a. autoreturn) mirror. The first commercially produced SLR that employed a roof pentaprism was the Italian Rectaflex A.1000, shown in full working condition on Milan fair April 1948 and produced from September the same year, thus being on the market one year before the east German Zeiss Ikon VEB Contax S , announced on May 20, 1949, produced from September. The Japanese adopted and further developed
10918-417: Was gradually placed on the need to dispose of e-waste more carefully due to the toxic materials it may contain. There has also been recognition that various valuable metals and plastics from waste electrical equipment can be recycled for other uses. More recently, the desirability of reusing whole appliances has been foregrounded in the 'preparation for reuse' guidelines. The policy focus is slowly moving towards
11024-490: Was immediately resaleable – or would be with minor repairs or refurbishment. This indicates a lack of awareness among consumers about where and how to dispose of EEE and the potential value of things that are going in the bin. For the reuse and repair of electrical goods to increase substantially in the UK, some barriers must be overcome. These include people's mistrust of used equipment in terms of whether it will be functional, safe and
11130-642: Was the most advanced photographic preview system available, but the recent development and refinement of digital imaging technology with an on-camera live LCD preview screen has overshadowed SLR's popularity. Nearly all inexpensive compact digital cameras now include an LCD preview screen allowing the photographer to see what the CCD is capturing. However, SLR is still popular in high-end and professional cameras because they are system cameras with interchangeable parts, allowing customization. They also have far less shutter lag , allowing photographs to be timed more precisely. Also
11236-508: Was worth US$ 240 billion annually worldwide comprising visual equipment, audio equipment , and games consoles . It was truly global with Asia Pacific having 35% market share, Europe having 31.5%, the US having 23%, and the rest of the world having the rest. Major players in this industry are household names like Sony, Samsung, Philips, Sanyo, and Sharp. Samsung Electronics is part of Samsung . In 2003, combined revenues for Samsung Electronics were $ 55 billion. Samsung Electronics UK
