NEX-7 + 50Lux-ASPH (current) ==> magenta cast/coloring smearing.

IF I intend to "BUY" any more RF lenses to adapt on A7/A7R, I will wait for more reviews first.

I don't have that issue with the Summicron on the NEX6 at all.

It could be because the rearmost element is much further from the sensor than in the Summilux:

I'll see how it performs on the A7r next month.

My guess is more on NEX7 vs NEX6, not so much Lux vs Cron.

I also have a 35Cron and 50Cron (both current, non-APO 50). At firmware 1.01, both performs clean on C3, "marginal" on NEX-7. The Lux'es are much better. At firmware 1.02, performance of 35Cron, 50Cron, and also Lux'es, flew down the drain on NEX-7, just horrible! My conjecture is: Sony FW 1.02 did something (accidentally) trashing (some) M-lens.

Can you provide pictures that illustrate the change in performance from before and after the FW update?
