I don't own an a7rII, but have rented one on a couple occasions - I'm going to try it with an original a7r first... Maybe the thin filter mod is important for wide angle lenses, and improves performance in the corners with either camera?
Under 24mm is really get out of trouble range for me, so not used very often(so good, but not great performance is acceptable). 24-35 is really what I'd use 95% of the time.
Hi,
Hans is using the 16-35/4 on Canon. There are some reports by Tony Northup and Ken Rockwell that it does not work well in the corners at 16 mm on the A7rII. Just in case you are considering that sensor.
I am much interested in trying out, but we don't have Lensrentals here in Sweden.
Best regards
Erik
