This M8 is the best collimation tool for LTM lenses that I can think of. I love it. Just collimated one of the sharpest Jupiter-3's that I've ever seen. It's F1.5 is about the same as F4 on a lot of my others. Just could not nail the focus with film and the scanner the way I just did with the M8. Changed the shim by 0.05mm, and could set it to minimize the focus shift going from F1.5 to F4.
This M8 is the best friend that a J-3 could have.
