Regarding the WATE\'s performance on the A7RII: it\'s really great at f/8 and it\'s almost as good as the Loxia 21/2.8 at this aperture (center and edges) but there is a visible mid-field dip. I\'m not sure if this is a characteristic of this lens or it\'s exacerbated by the thicker sensor stack.
Hi Fred,
I am not sure if the thicker sensor stack is an issue or if the lens suffers from a mid-field dip. Below is an image taken with my A7r prior to its modification to the A7rM V3 and my WATE set to ISO 50, f8, 1/3 second at 18mm. Focus was on the Yellow leaf on the left side othe rock in the lower right corner. Perhaps I have not checked the image as carerully as Fred, but I have found the limage extremely sharp throughout the image from corner to corner (even at 100%). The image was processed in LR6.4 and used the Lens Profile for the Leica M WATE set to 18mm.
