I see your point, but things like edge sharpness, CA, vignetting and distortion are nothing to do with AF Adjust and will not be effected by using it.
The way this thread is going, it will end up advising that ALL evaluation of ALL lenses is pointless as they're all different anyway, so the only way you can evaluate, is to buy one, test it, and take it back if not satisfied.
Really? You really think manufacturing deviations are such a problem? Are we not just making a mountain out of a molehill here? Even if there are tiny deviations in quality control, I've never, ever had a two examples of lenses that are noticeably different. If you have, can I suggest that one of them was faulty? Getting a faulty lens does not mean there is a problem with consistency, it means you had a dodgy one. There's a difference.
