RF800 vignetting
1

Last Friday I obtained my RF800 lens, and of course shot a lot of pics this weekend, with the lens mounted on my EOS R. Some of them even at very low light conditions: clouded skies and about one hour before sunset. My pictures are far from perfect, I know. But I remained with a question: Especially in the pics shot with high ISO I see a lot of vignetting. Is that to be expected, is it caused by my settings, or should this not happen at all with this lens. The picture below is shot at ISO 10,000, but I also observed it at lower ISO 3200. The picture below is a JPG of the unprocessed RAW image. The second picture is shot at daytime (ISO1250), just to show that not all show were as bad as the low-light ones.
