Vivitar Corporation was a manufacturer, distributor and marketer of photographic and optical equipment originally based in , . Since 2008 the Vivitar name serves as 's photographic and optical equipment brand.
The company's product line has included , , , , , ,
products, , , underwater cameras, and other photographic accessories.
Vivitar Series 1 200mm f/3, circa mid-1970s
The company was founded in 1938 as Ponder and Best by Max Ponder and John Best. Max Ponder headed the sales department, while John Best ran the operations side of the company. Ponder and Best first imported German-made photo equipment. After , 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 /Sekor 35mm cameras, Kobena 8mm movie cameras, Sankyo/Komura wide/tele adapter lenses and a full line of photographic darkroom equipment imported from many manufacturers throughout Japan and later Taiwan. Ponder and Best were the first to gain acceptance for lenses with interchangeable mounts allowing customers to use the same lens on different manufacturers' camera bodies.
In the early 1960s, the partners created the "Vivitar" brand to compete with major lens manufacturers. The company commissioned experienced lens designers and top-line Japanese optical lens manufacturers such as
to produce their lens designs. By carefully positioning their limited product line with key photo retailers, they quickly built a reputation for good quality lenses at modest prices. The retailers found that they could make good margins while giving good value. As their reputation grew, many contract lens manufacturer sought them out to carry their products under the Vivitar brand. In the 1970s, Vivitar introduced its now-famous Series 1 lenses. These computer-designed state-of-the-art lenses were well priced and often outperformed the optics of camera manufacturers of the day.
After the success of its aftermarket lens line, Vivitar later introduced its own line of 35mm film cameras manufactured by Japanese companies such as . These include the Cosina-made Vivitar SLR and the Vivitar 35ES/EE series of rangefinder cameras.
Vivitar also offered a new type of semi-professional flash unit from National/ under the Vivitar label called the Vivitar 260. The flash was acclaimed for its innovative design, but criticized for its use of expensive . Recognizing the problem, Max Ponder travelled to Japan to meet with the manufacturer, offering suggestions for improvements based on the feedback received from customers. The improved flash was introduced in 1970 as the Vivitar 283. The Vivitar 283 quickly became the number one professional and enthusiast flash unit, outselling all its competitors combined and selling 3,000,000 by 1973. In production for over 30 years, it was twice returned to production after being discontinued in response to customer demand. The 283's sister flash was called the 285, and featured a zoom head to cover different focal length lenses and a built-in variable power setting. Earlier made-in-Japan Vivitar flashes have a trigger voltage of 250v, which can damage the circuits of some digital cameras. Newer units made in China and Korea are low-voltage units producing 5 to 12 volts. A point of note is the 283 has a removable sensor (as has the 285) and coupled the optional remote sensor cord, off-camera flash is possible with the gun still in auto mode.
After the deaths of Max Ponder and John Best, company ownership was transferred to a variety of owners. Some digital compact cameras were launched but were not successful. In November 2006, the corporation was purchased by
Corporation for US $26 million in
and was operated as a wholly owned . On August 21, 2008, subsequent to its filing for , parent company Syntax-Brillian completed the sale of the Vivitar
based in . Sakar did not purchase Vivitar’s equipment, facilities or . Terms of the deal were not disclosed.
Low-end digital camera sold in 2011
In August 2008, Sakar announced plans to position Vivitar as a brand for its current mass retail
in the midprice range of $70–$300, along with certain camera accessories. New Vivitar-branded products such as
are also planned, as well as potential licensing opportunities. In January 2009 Sakar introduced 3 new Vivitar-branded cameras and a digital SLR lens series. The products are Sakar's first Vivitar-branded SKU's since Sakar acquired the Vivitar brand. In addition to other electronics products, in 2013, they announced and then shipped the $150 , a 7-inch
tablet designed for children, with a bilingual English/Spanish interface.

The term superzoom or hyperzoom refers to photographic
with unconventionally large focal length factors, typically more than 5×.[] The largest ratio for a
camera lens is held by the Tamron Di-II format () 16–300 mm, giving 18.8×. Some
have even larger zoom ratios more than 80x and the non-detachable lens compact cameras with same sensor size 1/2.3" as the bridge camera have superzoom up to 30×. The

holds the record with their 300X (7-2100mm, 23-7000mm 35mm equivalent) HD Lens with Compound Zoom Technology (two or more lenses mounted together).
While superzoom lenses have improved greatly in recent years, they still have a number of drawbacks in comparison with shorter-range zooms and , chiefly their typically smaller maximum .
has demonstrated that the best sharpness of a zoom lens can be at the wide-end, at the long-end or in the middle of the zoom range depending on the camera processor and not on the lens itself.[]
The longer the zoom lens, the greater the possibility of
when using the wide and widest angles, especially if optical filter(s) are attached to the front of the lens. Even at the longest range, falloff (darkened corners) can be seen. The magnitude of vignetting and falloff depends on the apertures. Opening a smaller diaphragm will usually reduce vignetting and falloff, but as a consequence of loss of ample light and loss of broad/deep depth-of-field.

The first zoom for photo cameras was introduced by
in 1959 (Voigtl?nder ZOOMAR 1:2,8/36–82 mm). It was in fact designed by an independent lensmaker
That same year
introduced a Nikkor 85–250 mm/1:4.0-4.5 for the new Nikon F.
The first zoom affordable for amateurs was the Vivitar series I 1:3.5/70–210 mm of 1973, with a breathtaking for its time focal length range. Other superzoom lenses included a 100–500 mm/1:8 Rokkor from
and a 360- Nikkor from 1976.
brought a wide-angle-to-zoom with the enormous focal length range of 1:4.0/28–85 mm to the market. Only two years later Tokina presented the first super zoom shot, for that time, which covered a focal length spectrum from 35–200 mm (1982).
The focal length range was again increased in 1985, when Kiron presented the first zoom lens with a focal length range of 28–210 mm.
