    To be honest I only spent $100 on the camera, I'm not looking to send it to a shop and I'll live with the off centre AF lights if necessary. I was wondering if anyone else experienced this and if it's a common problem or not.

    The focusing screens are the same as for the EOS 1V, and seven are still available. Check them out. They're only $32.

    That is exactly what he was talking about, and I also agree with his prognosis. The screen is not sitting properly in its place, likely because its place is tweaked.

    Indeed. However, the ones that were introduced after the EOS 3 (such as the type S) will cause the camera to meter improperly, so if you use your in-camera meter, take care to get one that works with the 3's meter.

    Personally, I got the S screen anyhow, since I don't ever use my in-camera meter. Works like a charm.

    You make a very good point, one that I had not considered. The focusing screen is frameless, therefore a new screen would likely do no good. It would almost have to be the seating in the camera body. Best have a pro look at it, if it's something you care about. Personally, that sort of thing would drive me nuts, and I would be delighted to spend whatever (within reason) getting it fixed.

    Pretty sure it's not to do with the screen. I reseated the screen, tested a different screen, reseated the different screen, removed the screen entirely, nothing changes the skewed position of the AF point lights.

    The AF points are superimposed onto laser-etched markings on the screen matched to emitters lined up directly above, and of course, any misalignment of the screen will be very obvious. I think a more sinister proposition is that the camera has received a severe knock that has bumped the superimposition emitters out of alignment, but at the very most, such misalignment would manifest as only a little more flare — that is to say, flare that is significantly more noticeable and adverse than normally occurs during the illumination process. The effect has been seen in several well-used and battered EOS 1/1N bodies where the screen has been frequently interchanged.

    Warped screen frames are the most common problem where changes have been made hurriedly, clumsily or incompletely — it is a delicate operation with the potential for damage to the screen especially from slippage with the tool, or damage to the frame by forcing an incorrectly seated screen. Irrespective of how much you paid for the camera, a bench examination by a qualified professional is called for now that everybody here has proferred as much as can be without actually physically inspecting the body.

    The screen of the EOS 3 has no markings for the AF points. They are simply projected on the screen. The 1 and 1N have different screens with markings.

    In the 1N, the markings are etched into the prism (not the screen). On the 3, neither the screen or prism has any etching - I think the AF lights are projected like a reflex sight. Presumably the only thing that could misalign them is the projecting device being off then? Which would be deep inside the camera body - I think I'll just live with it!
