A 75/80mm enlarging lens is another possibility, seem to be plenty of LTM to 
various other mount adapters available.

Perhaps just as well. In my tests of several macro lenses years ago, the 50/3.5 
Macro was not as good at 1:1 as at 1:2. 
Still pretty darn good, though.

Certainly so with OM mount as the OM 80 mm bellows lenses are optimized for 
1:1. The 80/4 Auto is THE answer with Oly bellows and slide/film copier.

My 80/4 Auto is not leaving.  The Tamron 90/2.5 (52B) Adaptall was designed to 
work to 1:1 with a matching extension tube, so should be good with bellows. In 
my tests, it was slightly better at 1:1 than the 50/3.5 (not as good at 1:2). 
The Kiron 105/2.8 is another possibility. Focuses directly to 1:1 with its 
double helical, and image quality is different, but about the same quality, at 
1:1 as the Tammy.

I believe both were available labeled as Vivitars.

Good luck!
