I've used mine quite a lot on my Sony mirrorless camera; granted, that's an APS-C format camera but I've been favorably impressed by everything I've shot with it.
You are quite right, the lens in the photo is in LTM mount. You know, in my rush to find an image with a lens in similar condition to my lens (which IS in Nikon S mount) I did not even notice that most obvious of differences.
Not the first, nor the last time, I fear, I will suffer from brain fade.
