Hi everyone, I have some problem with my D750. Since last week I change lens from Nikon 14-24 to Tamron 70-200, I have experienced extra exposure in all photos I take. No matter which lens I use, which mode I select, the extra exposure will always happen at the same places (clearly there is one strip area on the left-top corner, and a ring on the right of the photo, and there might be more but difficult to notice). You could see it from the sample photos I attached here.
Highly appreciate it if someone could let me know what's going on and how to fix it. Thanks in advance!
