Samuel, after 1.2 hours sitting near windows to adjust my m2, here my guide for u
Vertical alignment then just open the small screw above the lens mount, inside is a small screw, that screw damn easy to move, so can adjust easily
Horizontal alignment
1- Find some screw driver, the type that the head can change ,take the head only . I found that sometimes u cant move the screw cause the screw driver head only touch part of the screw, thus damn hard to move, and actually this screw much stiffer than the vertical one.
hold the little head w ur 2 finger can already
2- check horizontal misalignment, find some straight line in infinitive range , turn the lens to infinitive, tell me which case is it , image 2 is the one u have to match with , 1 ,3 is where ur lens stop when put to infinitive.
3 - If ur lens stop at 1, mean the image have to move to the left a bit to match 2 , turn the screw counter clock-wise ( I hope i remember correctly ) Do the opposite for other case, sadly now i'm not sure counter clock wise or not. *** Note : May require some fingers strength, u can do it
4- I dont think it can be wrong when u can match the image at infinitive, it's whether go over or can't reach , if it's match, most likely will be ok .
5- test w other camera, find somewhere u can focus at 1m, then use dslr or other cam to focus there and check whether it's true that its 1m
6- Happy, jump and sing
7- please put the small screw back.
8 - SHoot a test roll , mine i test w a 90mm, all come out sharp, so i guess no prob.
* for fine tuning , look for somewhere far ,focus on a straight line so easier to check in case ur misalignment not so serious but a bit.
