LTM vs M Collapsible Summicron

[msbarnes]

I know LTM summicrons have soft coatings and I believe that the M collapsible has soft coatings too, so are these two summicrons identical, except for the mount?

Thanks

Correct. No difference in optical design.

[paradoxbox]

they're the same

i've tried both types and they're both the same - both copies had scratches all over the front elements!

Thank you, you guys answered my question precisely.

Too many lenses to pursue :0

If I ever find a good LTM collapsible Summicron for a reasonable price, I'll snap it up. The problem is that even marginal ones generally command a higher price than I'm willing to pay. I might be too picky.
