Canon EF 400mm f/5.6L USM Lens Review

Canon EF 400mm f/5.6L USM is one of three 400mm primes Canon currently offers in its lineup of super telephoto lenses. This is the slowest 400mm prime, as well as the most affordable among the trio of 400mm Canon primes, priced at ~US$1,100 (as of October 2008).

Canon EF 400mm f/5.6L USM review by Leo

Never liked the EF 300 MM F4.0, the EF 100-400 mm was already better. But the 400 MM F5.6L surprised me. The IQ is very very good. For a short time I have had the EF 400 F2.8 ISL. The IQ of that lens is out of this world, as is the weight. You need a truck to get where you want to take your photo's.
