Thank you all for all this work. I have a good collection of M wides that I use with the old Monochome M. I am very interested in this tests for color wides and wonder what the A7S.Mod is? And if it would be possible to do the "mod" to this A7RII?So the next part, I'll only show the tip of the corner. I applied same vignette correction so you guys can see at 100% how much brighter the A7RII is. It's also easier to see the smearing here. The amount I applied is 3EV in C1. I also include the A7S.Mod result so you know what to expect in the corner.
I hate to be the bearer of bad news . There is no improvement whatsoever that I can see. If there is any, it would be minimal. The ZM 15 is an extreme case, nonetheless.
