I did a search and could not find any data so pardon me in advance if this has been discussed.
I have a Voigtlander 75mm f2.5 Color Heliar that I have used on my micro4/3 system. It is an extremely good lens for that format. However, I rarely use this focal length with m4/3 format. So i had considering selling it for about a year now.
It is not an extremely expensive lens and I am wondering if anyone has tried one of these or even the newer 75mm 1.8 version on their Sony A7r full frame -- or any full frame sensor for that matter. I am just wondering what type of results one gets.
I hate to spend a lot of money on an adapter if there is little change of a good outcome.
