I have aD90 with a 18-105 F1.5-6 kit .
When I try to take a picture in A,M,S,P or even in Auto mode sometimes, the F keeps flashing and wont let me take a pic.
If I turn it off and retake the same snap sometimes it works.
I am extremely agitated that it does it.
Can someone please help me with what am doing wrong.
It probably is someting very silly but yea I cant get it
