I'm with you eriet30, I also had no issues. Funny you mention FM standard, there is a thread from a new photographer with not much experience, he was worried that his few new lenses did not live up to being centered.. Well one of the accomplished photographers ( great work by the way) like many here shinned in and told him go out and shoot the lens as you normally would and enjoy it.. Then evaluate it. No need to get all neurotic about it. If you see something wrong then by all means do a few further tests which he went on to explain. By the way some of the suggestions were really helpful... Personally thats what I do, just go out and shoot it.. If something is wrong you will see it. Fortunately they always been within standard. What is difficult is moving to new system, you have to research it, and believe me I am happy its just about over.
Yes I read there was a Nisi,
This is what I use https://www.youtube.com/watch?v=GXGQYY84PwI&t=58s
I have a 82mm polorizer sprokett that I am able to use in the holder for my largest to my smallest mm lenses with stepdown rings.
I am not sure it will work with all the lenses I am looking into. Just not sure if the hoods are permanent or not.
I did see many felt the same was as you did regarding the 100-400gm
I appreciate your thoughts, thanks eriet30
due to a string of bad luck last year, I test all my lenses for centering.
That said, I'm forgiving of a little decentering wide open, but if it's fairly bad, I'll have it returned. Basically, if you have to do a double take at 100% to figure the decentered corner, then it's a golden copy. If it's there, noticeable, but not huge, I'm keeping it. Large discrepancies can mean something else and possibly even damaged product. I find that in practice, I'm getting pretty good corner to corner performance with all my lenses using this criteria. My CV 35 in M mount has curvature issues, but was still tested for decentering issues. It's acceptable, first copy was straight up poor.
