I just purchased this off eBay and I can't see the red focus point but at times I see a red blob. Ok, here is my thinking.. the focus screen looks like it has been changed. It is crystal clear with no marking what so ever. Could it be that I do not see the red focus points because the screen has been changed? I have tried resetting the focus screen, factory reset the camera, changed batteries and brands of batteries... You name it, I tried it. The camera is mint and is beautiful... I got a refund and was able to keep the camera and I love it and works amazing minus the focus dots, squares.. whatever ya call them. I do not even see the black focus box markings Can anyone help?
