Canon EF 400mm f/5.6L USM User Reviews

Telephoto prime lens | Canon EF | 2526A004

I have owned two of these lenses over the years and used them with 7D and 7Dll cameras. The first developed terminal fungus after years of use in a high humidity environment. My current copy has a little fungus but not enough to impair the images so far as I can tell. I go out almost daily on walks to photograph birds and this lens combined with camera and flash unit is the most weight I'm willing to carry around. If the other, more expensive 400mm lens options were lighter weight I might ...

This lens has been around a long time and when comparing it to the more expensive, higher profile Canon f2.8 and f4 400mm L lenses it's easy to underrate.  However, its simple construction yields high quality images and excellent colour rendition. Photographers using L lenses expect quality at all apertures, especially at f5.6 for this lens and this aspiration has been fully met by Canon.  Furthermore, thanks to the advent of cameras with the capability of reduced noise at high ISO's, the ...

Just took delivery and went out to the lake for a few test photos. The lens is superb. Even without IS, the lens rocks. My photos included tripod and handheld. Many were BIF's. The included photos are with Canon's 1.4xIII extender to bring the focal length to 560mm. The photo was at 1/500, f/18, ISO 400 in shutter priority. Using the extender the focus is center only, so you really need to be on your moving subject. While I did some moderate post processing, the lens shows its spot on sharp, ...

Cheap. Focuses quickly (Ring USM combined with few lens elements.) Light weight. Sharp at 5.6, no need to stop down. Resists Flare well. Built-in lens hood (sliding). Includeds tripod ring. Wide focus ring with FTM. Great lens for the money! Problems: Sometimes you want still more reach. At airshows, sometimes the zoom would be hand especially with larger aircraft (Lancaster, C-17, B-17, B-29 etc.) Minimum focus is not great.

When I changed from canon FD gear to EF I changed my FD 500mm f/8 reflex to this 400mm f/5.6L. This lens is sharp, focuses fast and like the 500mm reflex lens can still be used without a tripod. It has no visible distortion so there is no need for post processing corections. The review at http://www.photozone.de/canon_eos_ff/612-canon400f56ff fully matches my experience with this lens. Problems: None
