I am curious to see why the 85L II is so different from other primes in the standard focal length. For one, compared to the 85 1.8 it seems to have such a narrow depth of field even at f10 or smaller. Obviously the AF is already slow but it seems like it takes multiple shots to hit perfect focus when shooting with larger aperatures (on full frame body). When it hits perfect focus it is extremely sharp and produces incredible images but it seems as if it is really limited in uses because it is not always spot on like a 70-200 or even the faster 85 1.8. BTW, our family has three 85Ls (one MKI and two MKII) so I have verified that there is similar performance with different copies.
