I've corrected the vignetting so it can be seen easier. If I were to guess, the a7rII also has less vignetting, but I'm sure 100% sure on that. There's a nice magenta cast on the original A7. It was never bad (especially compared to the A7r), but you can still see it. The A7rII, on the other hand, looks really good in that respect. Original A7: A7rII: Side comment: I love how little distortion this lens has!
