I take a photo with the cap on, set to shutter priority mode and set to 30s. After photo is taken and the NR job runs, I end up with a black picture and a red line/haze down the right side of the photo and across the top of the photo.
- Should I suspect an issue with lens/body?
- What would you do to diagnose the issue?
- Am I over-reacting and this is just a known issue (only currently affects my astrophotography)
Nikon D90 with 18-200mm Nikkor and Nikkor 85mm f/1.8g lenses. ISO 2000+
NOTE: Have not experimented to see how low of an ISO I can go before the artifact disappears
