p.1 #1 · 7Artisans 75mm f1.25 II focusing adjustment
I just got the 7a 75mm f1.25 II and it is indeed quite a nice piece of optics. I got such a good deal that I am planning on keeping it even though the lens is not able to focus at infinity, not even close -- even stopped down to f/16 infinity is soft. The hard stop is at something like 25-50 metres at most.
I am not talking about the rangefinder calibration, which is intended to be done by the user, i am simply referring to looking through the EVF when focusing as far as the lens will go. Indeed as I mainly plan to use the lens with an EVF, I don't really
bother doing the rangefinder calibration for now.
Has anyone tried calibrating the infinity hard stop on these lenses yet? I see there are small screw holes near the focusing ring..... I also sent a message to 7Artisans Europe but so far still waiting for any response.

I hadn't seen that, thanks! Looks easy enough. Just would like confirmation from someone who has done it already, that this is also the technique to use for the 75mm f1.25 II. As a much bigger lens the way how the mechanics work might be diffferent from this much smaller lens.

i was able to return the lens and got another one. in the second lens the infinity focus hard stop and the rangefinder coupling appear spot on or close enough.
