jukka,

Not sure if you saw my previous post, but do you know the answer to this question:

Since AFMA for a particular body/lens combo changes as a function of subject distance, it's not possible to have an AFMA value for all subject distances. Is this any different for a lens that appears to require 0 AFMA? I.e. will it also have 0 AFMA for all subject distances?

hmm My Finnish English do not understand what you're asking, can you simplify the question and I try to answer

Ok, let me try to rephrase.

Let's say you get a 85/1.2 prime lens that needs no microadjustment for perfect focus. Will it focus perfectly for both close & far (infinity) subjects (at f/1.2)?

My 85/1.2 needs a microadjustment of +12 for a subject distance of 25x focal length (~85 inches distance). But now infinity is no longer perfectly in focus.

So what I'm asking is: since the AFMA value you enter into the camera is only really valid for the subject distance you used to determine that AFMA value, is it better to get a lens that appears to need

**no microadjustment** whatsoever with your body?

Or will even those lenses show different back/front-focusing for subjects at various differences?

Of course, I'm only speaking of wide-aperture primes here... Above f/2.8 or f/4 you won't even notice these sorts of variations (unless your lens is really, really far off).
