As per the thread title, are you going to send your DSLR to the service centre for cleaning if you found out that there is something not usual on your body?
Lens used is 50mm
However, when I was shooting at other apertures with the same lens, this image doesn't show up.
I have tried also with another lens with same settings, it is there also. That's why I think it is on my DSLR body.
Thanks for your help!!!
