the Canon EF 70-200mm f/4L USM Lens will make you smile when reviewing at 100% on a monitor. This lens is
very sharp wide open and improves only slightly when stopped down - and primarily in the corners at the wide end of the focal length range. Very slight barrel distortion is noticeable at
70mm on a
Full Frame body. Distortion disappears by around 100mm and is insignificant on a 1.3x or 1.6x FOVCF body. Vignetting is very well controlled - full frame users might notice slight vignetting in the corners at
f/4. CA is very well controlled.
The Canon EF 70-200mm f/4L USM Lens focuses very fast, very quietly and very accurately thanks to Canon's excellent Ring
USM (Ultrasonic Motor). FTM (Full Time Manual) focusing is enabled. The focus and zoom rings are very nicely sized and turn very smoothly. The
70-200 f/4 does not extend with zooming or focusing - and the front element does not rotate.
