Noobie here, may be a stupid question but would really appreciate any input.
I got a heck of a deal locally on a 5D mk i with a rokinon 14mm lens. It was untested and didn’t come with a charger. I bought a charger and when I finally powered the camera up, the viewfinder only displays a tiny circle, and it’s bordered in black. I can see the aperture open and close, but it won’t open fully. I’ve attached a photo.
Cheers
