MA works best on primes from my experience.
Most of my lenses are spot on, so I only need to MA 2 of my lenses.
On a zoom, what I typically do is if there isn't 1 MA value that does it for all focal lengths, then I will write down the MA value needed at the long end and the short end and average it out.
However if my lens is really out of whack, I usually send it in for recalibration...

How does the micro adjustment feature work on new Canon bodies, and are there limitations? Eg workign better on a prime than a zoom? Just wondering if a focus adjustment at eg the wide end of a zoom would still work at the long end?
Or do you end up trying shots at different adjustments and different lengths, and picking the best compromise?
