Hi all,
I just bought a brand new Eos 85 1.8 EF and popped it on one of my my Eos 3 bodies. The lens focuses fine through the viewfinder and images appear to be in sharp focus; however, when I inspected the negs they are not even remotely in focus.
Frames shot close up, say 1-2 metres show the camera is focusing behind the subject by about 5-6cm and when I shot at a target about 100ft away, correct focus was about another 50-70ft behind that (the subject area looked like the bokeh and what should have been bokeh was sharp)! Infinity subjects looked like the camera was focusing way beyond infinity because as blurry as they were, closer scenery was even worse!
For subjects at about 1m, the blurry images gets WORSE as I stop down in many cases.
I have not used this Eos 3 body for a while, but have never had problems with it. I am inclined to think the issue is with the lens. The problem is that I am away from home and will be for months so cannot test it on another body. The only option I have would be to return it and get a replacement by post.
Is it possible for a lens to *appear to focus* thru an SLR viewfinder but actually be miles out due to a lens (rather than body) fault? As it stands the set up it completely unusable at any aperture or distance. Images don't even look remotely in focus and I am getting much less resolution on the film than I am wide open through the viewfinder. The body remains in very clean condition and has had no knocks. I just inspected it and cannot see any damage, but of course I cannot be sure...
Any thoughts? If the lens, I don't get how it could appear to be focusing but registering very badly on the film. My instinct suggests a body problem, but this body has been perfect in the past and I am unaware of it suffering any damage.
This is a huge pain in the ass as I brought the body out here to augment the Ms for a particular project. I ordered the lens, did a quick test and now have no idea whether the lens or camera is the issue...
