Last evening when I was out filming with the XTR, I was attempting a shot (on a tripod) which was looking straight up at the top of building (camera almost parallel to skyscraper).

After I changed lenses in between shots, I suddenly noticed that the image that I was looking at through the viewfinder was somewhat blurrier (the focus had not changed at all) than on the previous shot.

I tried all four of my different lenses--to no avail--the image is still blurry...maybe I'm crazy, but it seems even more blurry today than yesterday.

I was thinking that maybe a drop of water got on the mirror or something happened to make it foggy, in between the lense change...cleaning the mirror hasn't seemed to help...

I'm at a little bit of a loss...any ideas?

Thanks

It is not clear what you mean when you say "the focus had not changed at all". Focus of what? The lens or the viewfinder? I am just wondering whether the diopter setting has moved. This could easily happen if the locking screw has worked loose. So, simple check first ... have you checked the diopter setting?

My bet would also be on Diopter.

Thank you for your quick responses.

I got it figured out.

For anyone else using the Aaton, make sure to be aware of the diopter on the XTR--the lock for the diopter ring is not the best and it can come loose pretty easily.

I have an Aaton XTR and I just got a adapter for C-mount lenses (PL - C-mount).
Just tried the C-mount lens with the adapter and it's all blurry. Diopter is correct so it's not that.
I've never used this camera before, recently got it. Any ideas?
I got the adapter here:
