Hello everyone,
I have some vignetting issues with my new Lens (Sigma 100-400 mm /5,0-6,3 DG OS HSM (C)). At f/8 there is still a terrible vignetting visible (see pictures below). With some test pictures I could even see vignetting up to f/13 with the eye and f/18 (!) if I equalized the picture.
Does anyone have an idea what might be the reason for this?
I'm also aware of a previous related thread (https://forums.jetphotos.com/forum/a...gnetting-issue). However, in this thread f/8 (or higher numbers) and a Sigma 100-400 lens were part of the solution, not part of the problem.
Original picture (just the raw developed into a jpg): Picture is taken with a Nikon D800, f/8 and 250 mm focal length. I'm aware it's not cropped as I wanted to show the full effect:
Equalized picture (equalizing in Photoshop; the JP tool will probably look even worse; I know about the multiple dust spots):
Thanks for any help and best,
