    Optically, what relationship between the 75 and the 80?

    The 75 and the 80 are identical, except that due to the smaller form on the M the focal length was changed from 80-75 so it matches the 75 frame lines then. It was not possible to make it a 90 and still retain the f1.4.

    The 80 is a bit better, but optically they are the same. You will see this when you compare images from the two. However the 80 is a bit better overal. Size wasn't a problem.

    Did they just change the distance between the front and rear modules? Is there a measurable difference in the physical length of the two lenses?

    I've changed focal length on a few lenses before, changing spacing between front and rear groups. The change in space between the optics versus the (small) change in focal length surprised me.
