Hi D7100 user, I just get mine few weeks ago, I tested and there are some dirt spot I think should be on the sensor, I send back for replacement and unfortunately body only sold out and only available 4 weeks later, so they decided to send back Nikon for sensor cleaning. I just collect back my camera, then I found out that the dirt spot are still visible, but much more better than previous, then the shop guy tested on another D7100 still have the problem, just asking if anyone of you face the same problem? Do you all have anyway to solve this?
