Special thanks to Markus Stamm for providing this lens!


Sometimes you recognize that you lot’ve missed something just at the time you lot experience it. And the Canon EF 85mm f/one.2 USM 50 is one of those lenses where your brain switched off anyway due to the combination of frightening pricing and insanely big aperture. Apropos large discontinuity – information technology looks like this …

On paper the EF 85mm f/1.ii USM L is usually described every bit a portrait lens though this scope is certainly much wider. Using an APS-C DSLR the field-of-view resembles a
lens in full-format terms.

If yous ever wondered when to employ extreme shutter speeds this question will not ascend with this lens. On a normal day it is oftentimes incommunicable to use the f/one.ii setting simply considering there’south too much low-cal and your camera merely can’t provide a shutter speed fast enough for this. During the field tests I frequently ran into the 1/4000sec limit (@ ISO 100) of the camera. Then if you intend to use this lens at large discontinuity settings in daylight consider to invest into a gray filter …

The lens features a outset generation USM AF bulldoze with a front end group linear extension system – therefore the length of the lenses changes slightly during focusing. A specialty of this lens shared with another early EOS lenses is the
manual focusing by wire. The focus gear isn’t direct coupled to the focus ring – all the action is done by the USM drive here. Usually you’ll not even recognize this but full-time manual focusing is not possible with this lens. The quality of the construction is very high. I’m not sure whether the outer butt is fabricated of plastic or metallic but this is tough stuff. On top of that the lens has some rubberized portions like to a skilful quality camera grip – something that I haven’t experienced with other lenses so far. The supplied, butt-shaped hood (clip-on type) is very deep and should be quite efficient.

AF speed feels quite fast merely a little nervous with this lens. Regarding the shallow depth-of-field of a f/i.2 lens this isn’t really surprising here. At large apertures it is extremely tough to hit the exact mark that yous want to have in focus. The minimal focus altitude is 0.95m resulting in a max. magnification of 0.11x or ~ane:9.

The optical construction is fabricated of 8 elements in 7 groups with 1 aspherical lens element and ii high-refraction elements. This is certainly needed in lodge to keep the aberrations at wider apertures under control. On top of that the lens features a floating organization to correct coma and for improved close focus operation.

Regarding the gigantic size of the lens elements a weight of 1025g can’t be avoided. However, with a dimension of 91x84mm information technology may exist a petty fat just it isn’t really a large lens. The filter size is 72mm and there’re 8 aperture blades.
