on my 1.3x crop Canon 1D Mark III digital SLR it gives an even longer effective focal length (176mm) but I love it for 3/4 length fashion shots when you want to blur the background and you have 3m or so to spare from camera to subject, but it also works very well as a portrait lens with its shallow depth of field (DOF) and lovely bokeh
it is very susceptible to flare so using the big lens hood is almost mandatory in any light!
sharpness improves as you stop down so by f/4 the 5D sensor resolution is limiting sharpness, no longer the lens.
a great portrait lens, especially for indoor performance photography but too long for the cropped sensors for indoor portraits
it can be used via adapter on an Olympus OM-D E-M5 camera to give an effective 270mm f/2.0 image stabilised manual focus lens (yes I know the DOF is more like a 270mm f/4 lens but when shooting at 270mm focal length you don't generally want shallower DOF than f/4)
specs
$A1879; 750g; 72mm filter;
NOT weather sealed!
min. focus 0.9m ⇒ 0.19x magnification on full frame
USM rear focusing AF with full-time MF
focus limiter switch - full range or just 1.6m to infinity
10 Elements in 8 Groups, two UD elements, internal floating design
designed to be used with EF extenders - 1.4x or 2x with “minimal” loss of image quality
at 3m focus distance, at f2.0, depth of field (DOF) is still only ~6cm on a full frame camera
supplied with ET-78 II bayonet lens hood which is indispensible with this lens
at f/2-4 it is sharper than the 100mm f/2 or the 85mm f/1.8, with more micro-contrast on full frame sensors, and has better background blurring for the same subject size
as sharp as the Canon lens is, it is not as sharp as the Zeiss, particularly across the frame at f/4 or wider, however, the Zeiss lens is only manual focus and is twice the price
