Possibly for infra-red photography, on those cameras which are sensitive in that non-visible part of the spectrum, the focus markings may be shifted. I think some lenses have additional markings to show where infinity would be for IR light. That could be a reason for having some leeway in the hard stop.
It takes 10minutes to remove the lens mount and shim it to have hard stop on perfect infinity. I use my lenses in freezing cold and really hot conditions, never had a problem with lenses that would have extended and move my infinity setting. It’s unfortunately an urban legend, just look at Leica lenses, they are set with accurate infinity setting on the hard stop. Try to shim your lens and experiment with it, you will see how confortable it is to have it on hard stop and just point and shoot :)
That may be a good solution for the TTArtisans flange distance problem, but it would be a bad idea for these Noktons as it would put the distance scale off. As I said in the video, this is not a flange distance problem, but rather a deliberate design choice, probably for temperature reasons. It would be especially a bad idea for a photographer like me who spends very little time with his lens at infinity.
@@XF74 I want my distance scale to be accurate so that I can use zone focusing easily, or actually measure the distance when shooting studio video.I spend so little time with my lens racked over to infinity that it makes little sense to fix a minor issue by creating a major problem. Besides, it would void the warranty.
Glad you made a video on on this topic! Thank you!

Very true, for me it is much more confortable to adjust hard stop at infinity, and use focus peaking for shorter distances if needed (on Fuji X-Pro1)
