Canon EF 85 mm f/1.8 USM

10. Autofocus

The specimen, tested in 2006, on the 20D in studio conditions had about 8% of misses. What’s more, it also showed a distinct back focus tendency.

It is not a big secret that EF lenses “spread their wings” on 1D series cameras. In this case we saw the same positive change – cooperating with the EOS 1Ds MkIII the Canon 1.8/85 worked noiselessly, quickly (it run through the full range of the distance scale in only 0.5 of a second) and, what’s the most important thing, very accurately. This time the number of misses in studio conditions didn’t exceed 2%.

What’s interesting, the second specimen of the Canon 1.8/85, available in our editorial office, also showed a back focus tendency on the 20D. We haven’t observed such an effect on the EOS 1Ds MkIII.
