I have a problem with blurry focussing dots in the optical viewfinder of my Canon EOS 1300D. I'm struggling to take sharp photographs when using the OVF in manual focus mode.
The circular dots in the optical viewfinder (OVF) are blurry. I can take sharp photographs when using autofocus or the digital viewfinder, so I don't think the issue is with the camera itself, but the OVF focus.
I'm talking about the "AF point activation indicator" dots here specifically. The AF point boxes around them appear sharp.
I have tried adjusting the diopter dial but the OVF spots inside the autofocus squaures remain blurry. When the diopter dial is turned clockwise then the OVF display goes further out-of-focus. I currently have the diopter dial turned fully anticlockwise, and it won't rotate any further.
I use the spots in the OVF to help focus using manual focus mode. When the red dots flash then I know I'm focussed on the targetted subject.
I wear glasses, if that makes a difference.
What could cause my OVF spots to be blurry?
