I have a D7100 that i bought a few months ago, lately i have been having a problems im my auto focus, which means basically when i press the shutter speed halfway the camera doesnt auto focus.
On the small screen top right, there is no Af-s written or any other auto focus modes written ( Af-s, Af-c ...), it just disappeared.
To remind you guys that on the lens its A/M and not manual, and on the camera its also M/a. I tried to turn on and off my camera many times and try many modes and still the AF modes arent visible on the screen top right.
I am frustrated because i was taking some shots and suddenly it stopped working.
I tried different lens as well and the problem still the same.
Please help me , I do have the warranty but i want to know before i go.
/edit - sorry, missed the last part of your post. :/ /edit2 - even though you've tried another lens it still looks like a physical problem with the lens seating. Is there any play in it? Even though it's clicked will it rotate a fraction more?
