I have an issue with my Nikon D3100:
Some of the shots show lines over the long edge. At first I thought it was only happening when using the Sigma 70-200, but after some thorough testing it appears to happen with my Nikkor lenses (18-55mm, 35mm) also. Sometimes it is just a few lines, other times it´s many.
I´ve been in touch with Sigma and they tell me it is probably my sensor suffering from interference of the sound equipment used at concerts. That was easy to dismiss, performing tests in different situations.
Then I contacted Nikon and they tell me it is probably due to my SD card. Well, I use several (SanDisk, Kingston) and the problem shows with every card. Currently, I can throw away about 25% of the shots taken at every session.
My question to you is to please look at the sample shots and tell me if any of you has seen this before? If so, what was the solution (if any)? What are your thoughts?
Photo 1 shot with Sigma 70-200 @ 200mm, f/2.8, 1/250sec, ISO3200
Photo 2 shot with Sigma 70-200 @ 120mm, f/2.8, 1/400sec, ISO3200
Thank you for your time.
