Ronny, Gregg, Charles, Basso; thank you so much for inspiring comments.
Basso, the last posted image was rather flat and dull light-wise so extra PP had to be used to add some life to it. Actually, I planned to shoot this building at night as it has interesting lighting.
hiepphotog – I don’t think colour casting with wide(er) angle RF lenses is specific to Sony A7 series cameras. If you search for images taken with Leica M9 or M240 without assign lens profile I believe colour casting will be the same. It’s either corrected in the camera or during the post.
I am still learning how to process colour cast removal, but lens profile in Adobe ARC and good lens profile for CornerFix are essential, IMO. If using CornerFix, refrain from correcting vignetting (Chroma = 0) and use vignetting reduction in ARC to minimize it and colour casting even for shots in f/8 – f/11 range.
Again, I absolutely agree that the extra PP steps are worth benefits of using smaller & lighter lens and sharp images across the frame, at least on modded cameras.
