Superzoom

From Wikipedia, the free encyclopedia

The term hyperzoom or superzoom is used to advertise photographic zoom lenses with unconventionally large focal length factors, typically more than 4× and ranging up to 10×, e.g. 35 mm to 350 mm. The largest ratio for digital SLR cameras is held by the Tamron 18-250mm, giving 13.9×.^[1]. For movie and television use, Panavision holds the record with their 300X HD Lens.^[2]

While superzoom lenses have improved greatly in recent years, they still have a number of drawbacks in comparison with shorter-range zooms and prime lenses. Most notable is the much increased likelihood of significant distortions of the image at both extreme ends of the range. Other potential problems include smaller maximum aperture and poorer autofocus performance.^[3]

Following is a list of such zooms, used for 135 format in SLRs or for APS format in DSLRs. The minimal factor used here is more than 5×. A 28-200 mm have a 75.4 to 12.3° angle of view, a 28-300 (or a 18-200 for an APS DSLR) have 75.4-8.2°. Between parenthesis are the Photodo rating, if any.

[edit] History and development

The first zoom for photo cameras was introduced by Voigtländer in 1959 (Voigtländer ZOOMAR1: 2,8/36 82 mm). It was in fact designed by an independent lensmaker Zommar from Long Island, New York.

That same year Nikon introduced a Nikkor a 85-2501/4.0-4.5 for the new Nikon F.

The first zoom affordable for amateurs was the Vivitar series I 3.5/70-210 mm of 1973 with at that time a breathtaking focal length range. Further superzoom was a 100-500/8 mm Rokkor fron Minolta and a 360-1200 Nikkor.

1980 brought Tokina a wide angle - to zoom with the likewise enormous focal length range of 1:4,0 /28 85 mm on the market. Only two years later Tokina presented then first superzoom shot after the today's understanding, it also covered a focal length spectrum from 35-200 mm (1982).

The focal length range was again increased 1985, when Kiron presented the first Zoombjektiv with focal length range of 28-210 mm. Tamron could do 1992 for the first time an appropriate, however additionally also still particularly compact zoom, which Revoluzoom bring to 28-200 mm on the market.

For the professional requirements of photo reporters that brought much used Canon EF 35-350 mm 1:3,5 - 5.6 L the break-through. Sigma brought a superzoom shot with 1:4,0 - 6,3/50 500 mm focal length. The use of aspherically polished lenses and of Gläsern with very low color dispersion improve substantially the illustration quality of many zooms. The additional installation of optical vertical image control systems as with Canon the EF 28-300 mm increases the range of application in addition.
