I know that this has been well documented, but there is quite a bit of conflicting information.
My main lens on Sony A7rII is the 50mm Sony FE 1.4, which is really good but heavy and (for me) kind of defeats the purpose of lightweight mirrorless.
Anyway after reading about the problems with wide angle Leica glass I left it alone. However I tried a Summicron v.IV and it worked flawlessly, I also have a little Elmar f4 90mm macro which is simply stunning on the A7rII.
My question is: has anyone had direct experience with the new version of the 50mm Summicron, the Leica 50mm f/2 APO-Summicron-M ASPH on the Sony A7?
Sorry for such a subjective topic, I live in Madrid and there is no option to rent and try.
Thanks
