I had earlier asked for help for solving my Sigma vignette issues and had a lot of solutions posted. I was asked to post my findings when the problem was identified. This is the response I received from one of Sigma repair sites (CRIS): AFTER CONSULTING WITH SIGMA USA REGARDING THIS ISSUE, THE LEVEL OF VIGNETTING PRESENT HAS BEEN FOUND TO BE WITHIN MANUFACTURER'S SPECIFICATIONS

I had another photographer from a local photography club use my lens with the same problem. We both have D7100. When I used his Nikon zoom lens I had no issues. When he used my lens he encountered the same vignette problems. These were the settings we experienced vignette issues-18mm 3.5 aperture and 1/60 shutter; 48mm 4.8 1/4; 82mm 5.3 1/500; 50mm 4.8 1/25; 46mm 4.5 1/250; 38mm 4.2 1/250; 92mm 5.3 1/250 etc .. I will just have live with it and deal with problem in pp. It was not polarizer problem- just the lens.

Is this the new Sigma 18-300mm F3.5-6.3 DC Macro C (Contemporary)? If so, it is the same lens I recently purchased to replace my 18-250. I will be following this topic closely. I did have some minor vignetting issues with my old lens but thought it might have been a badly connected lens hood. Were you using a hood?

You mention no ISO settings. Usually, the higher it goes, the greater the vignetting.

Not the expert, but I would think that the higher the ISO, the smaller the lens opening (as less light would be needed on the sensor) and therefore less affect vignetting??
