Why Micro AF Adjustment is...
Apr 29, 2013

I have, over the years, done every way of testing and calibrating my gear and have always been left baffled by weird and inconsistent results doing micro AF.  Things like +5 and -5 giving the same results which makes no sense.  This is with 3 different camera bodies over the years (7D, 5D MIII and 6D) and many lenses.  I've done the test charts, objects in a slanted line and most importantly, real-world shooting of the same subjects with adjustments as I go.  I usually just give up each time I try.  Today, I finally realized that the results depend totally on what the exact distance is and if you find a +5 at 3 feet works repeatably on a front-focusing situation, move just a few inches closer or farther and it totally changes!  Maybe it's supposed to be this way, and if so, I give up.  I have a really good eye and know what I am seeing and it's always just been consistently inconsistent.  Most people probably don't look as close as I do, but really, spot-on isn't impossible if Canon were calibrating everything right.  My Sony equipment never is off no matter old or new lenses.  Ok, I just had to vent!  Bill
