Английская Википедия:Canon EF 200mm lens
Шаблон:Short description The EF 200mm USM lens is an L-series prime telephoto lens made by Canon Inc. for the EOS line of cameras. Four 200 mm primes were made: Шаблон:F/1.8, two Шаблон:F/2.8, and the most recent Шаблон:F/2.0.
The 200 mm Шаблон:F/1.8 USM lens, introduced in November 1988, is the fastest 200 mm ever produced.[1] It is a large off-white lens with rear drop-in filter tray. Production was discontinued in 2004. It featured an unusual "focus by wire" system where the focus ring drove the motor when focusing in manual mode. This functionality was shared with only one other lens, the 1200 mm Шаблон:F/5.6 USM lens from Canon. The lens was used in the SuperWASP extrasolar planet search.[2]
The 200 mm Шаблон:F/2.0, introduced in April 2008, comes as a successor for the above discontinued 200 mm Шаблон:F/1.8. It is a large off-white lens with a rear drop-in filter tray and Image Stabilization.
The 200 mm Шаблон:F/2.8 lens is an inexpensive long prime. The first model, introduced in December 1991, had a built-in hood. It was discontinued in March 1996. It was superseded by the 'mark II', which is similar to first model but with standard bayonet hood, and is still in production. These lenses are Canon's second least expensive L-series lens behind the Canon EF 70-200mm lens Шаблон:F/4.0 zoom L-series lens. It exceeds the Canon EF 70–200 mm lens Шаблон:F/2.8 I in optical quality by a slight margin, but has since been overtaken by the Canon EF 70–200 mm lens Шаблон:F/2.8 II. In comparison, it is significantly cheaper, lighter, and less conspicuous, but at the expense of the ability to zoom. There is no Image stabilizer.[3] It sports a ring USM allowing full-time manual focusing. The minimum focus distance is Шаблон:Cvt. It is Canon's longest L-Series lens that is painted black.
All the aforementioned lenses are compatible with the Canon Extender EF teleconverters.
Crop factor
When used with a Canon APS-C (1.6× crop) DSLR camera or APS-H (1.3× crop), the field of view of this lens is similar to a 320 mm or 260 mm on full frame camera.
