Possibly the most under-rated lenses of canon and nikon, the f2.8 200/180mm.
Sharp, lightweight, cheap and compact lenses compared to the popular 70-200 zooms.
The Canon is a lot more adaptable (I am using on a Sony) than both the Nikon and even the old Sony A-mount screw-drive/Minolta lenses.
Been impressed with the sharpness (as good as the nikon). Size and weight is very close too, canon a fraction shorter and a fraction heavier.
I wish canon did aperture rings (one of the reasons I ended up with Nikon before the sony)
Full time manual focus override is good. Focusing is quite quiet (but I would much rather have the Nikon bombproof screwdrive). Focus feels better than nikon.
Hood too large for my application so I got a rubber screw in B&W one.
Wish it was 180 rather than 200mm although I am sure it sits between the nikon and minolta 200mm in focal length
