The 600mm f4L IS II that I had for a while needed AFMA of +6 on all of my bodies and it sure made a difference once I corrected it. The first 400mm f/4 DO mk2 that I tried needed +18 right out of the box. The DO was so bad that it was exchanged right away. Neither of those lenses is a budget model. I wouldn't just trust that because it is an "L" lens that it can't benefit from AFMA. Having said that my 100-400 mk2, 70-300L, 300mm f/2.8 mk1 and mk2 were all perfect out of the box. If you are going to spend all that money on a lens I suggest it is worth at least checking that the AF is properly calibrated.

no that you have mentioned it, i might try that! i know my 600 f4.0 II doesn't do well with both canon TC IIIs, so that might be one reason. i know my 300 f2.8 II is very sharp with/without TCs. but i might try my 100-400 II as well. my 100-400 II is pretty sharp without TC but slightly mushy (slightly noticeable) with using 1.4 III TC.  i have plenty of time so i could spend a few day doing it if i have to once the weather warms up a bit! thanks for the tip.
