Hi everyone,
I recently started using the Canon RF 15-35mm f/2.8L with my EOS R, mainly with regards to real estate photography where I'm capturing as much space as possible on interior photos. I had a quick question for anyone with experience with this lens. I used to use a 16-35 F/4, and here's my slight issue - with both lenses, there is some mild distortion. With lens/profile correction in Lightroom / Photoshop, the 16-35 gets all the lines perfectly straight. On the 15-35, there is still a little distortion where the lines that would be completely straight on the 16-35 have a slight bend to them. The "bend" once profile correction is checked is very minimal, but it's still just not quite as flat/straight as they are on the 16-35. Is 15mm just a little too wide to keep it completely straight, or are there any options/settings that can be used to remedy this? Any input is very much appreciated!
