Canon EF 400mm f/2.8L IS USM Reviews
Ephotozine reviews the Canon EF 400mm f/2.8L IS USM and writes;
“There is a huge amount of high quality glass in this lens, accounting for most of the weight. One fluorite and two UD elements are used to help control secondary spectrum. Suffice to say that, with everything taken into account, contrast, distortion, CA, OOF highlights etc, this lens produced excellent results.”
The-digital-picture reviews the Canon EF 400mm f/2.8L IS USM and writes;
“IS is excellent for many other situations the 400 f/2.8 might be useful for – such as wildlife photography. Wildlife tends to be most active in the low-light hours of the day. The 400 f/2.8 IS’s wide aperture, long focal length and IS make it an excellent wildlife lens.”
Photodo reviews the Canon EF 400mm f/2.8L IS USM and writes;
” At f/2.8, it is a fast lens for its length and works ideally indoors under lights at such events as fashion shoots as well as on the touchline or a fast bend. It also combines well with Canon’s teleconverter range, still giving autofocus with the 2x.”
