Tested it with a 55 & 85 SMC Takumar as well as with a modern 50mm Zeiss ZA Planar T and was surprised to see that indeed none of them had infinity right.
Wouldn’t say it is tac-sharp, and small text is still not readable, now matter how much I fiddle. But it definitely improved the situation. Thanks.
PS: I have the v5 and the front still has a little bit of wiggle room, so you still have to be careful when focusing by hand.
