Optics Theory - This forum is aimed towards the TECHNICAL side of photographic OPTICS THEORY. There will be some overlap by camera/manufacturer, but this forum is for the heavy duty tech discussions. This is NOT the place to discuss a specific lens or lens line, do that in the appropriate forum. This is the forum to discuss optics or lenses in general, to learn about the tech behind the lenses and images. IF you have a question about a specific lens, post it in the forum about that type of camera, NOT HERE.

Jupiter 8 on m42?

I'm impressed by the images on the Jupiter 8 thread and as I love the rendition of Sonnar lenses began to think of getting one. However when looking at samples on the auction site it became apparent that apart from a few which are modified e.g. for Nikon, they're all ltm m39 thread.

This raises the question of compatibility for m42. The flange-film plane distances for the two standards are different - 45.2mm for m39, and 45.46 for m42. Granted the difference is small - 0.26mm - but I would have thought this is significant, especially at large apertures and close subject distances. What do people think? And are any of you using J8s on m42? Appreciate any comments.
