Hi Jack
Very nice shot
How is Leica 21mm Super-Elmar-M f/ 3.4 ASPH on A7R II ?
see you are using A7R M
Is A7R II, equal to the A7 R bit worse performance of Leica lenses ?
Hi Ronny,
I'm happy to chip in here from my experience with wide-angle m-mount Voigtlanders - 15mm III, Ultron 21 F/1.8 and Ultron 35 F/1.7. The 15mm has always been fine, but latter two both suffered from both field curvature and a peripheral magenta cast on the A7R, with the 21 showing the more pronounce colour shifting. On the A7RII the field curvature remains but is manageable, but the colour shifting towards the corners is effectively gone, showing up only very rarely on the 21mm. My M-Hexanon 50 (poor-mans Summicron) and Elmarit-M 90 are just lovely on the A7RII. Regards, John.
