5D MkII Focus Screen dropped randomly?!

[Grant]

This was a shock, I was out shooting today, and I was swapping a lens over with a friend to see if it fit. Turns out it didn't, anyway, as it was an EF-S lens that wouldn't attach to my camera.

I re-attached my 50mm f/1.8 and looked through the viewfinder to see the most horrifying thing! A mash of random reflections and what not. So I opened it up and realised instantly that the ground-glass screen had dropped down onto the mirror >_<!

Is this due to me trying to attach the EF-S lens? Or is there a bigger issue hiding here? It's never happened before, or since.

Cheers!

the ef-s lens shouldn't have entered far enough into the mirror box to any damage due the the alignment lugs being in a different place.

EF-s lenses do protrude further back into the camera body though, is it possible you could have been off square with it.

My gut feeling is that it wasn't clipped in place properly, did you refit it ok?

I've had this exact same situation and I completely cacked it. Don't worry though, it's just the focus screen, it just needs carefully popping back into the frame and the lid closing. Run a search for replacing a focus screen

Yeah I've already done all the business with focus screens before. Swapped them for architecture photog/etc - Was just worried that I may have caused some serious damage. It was popped back into place with the help of a cafe spoon and all is good so far!

So Tomas, you say this happened to you with trying to fit an EF-S Lens on a FF?

Nope, only dummies do that!
Only jokin
I bought a second hand 1Dmki and during delivery the focus screen fell out into the shutter chamber. Cacked it and the nice folk on here told me to chill and helped me out.

hehe, I don't even know why I tried it. My friend wanted to see what a cropped frame lens would look like on FF. My Tokina was cropped, and fit. didn't realise the EF-S was an entirely different mount.

Wow, so weird I had the exact same thing happen to me when I tried to fit an EF-S lens on my 5D! I totally freaked out, but then was relieved and surprised to find out from a google search that this happens to a lot of 5D users. Does Canon intentionally loosely fit the focusing screens before packaging?

If the EF-S protrude further inwards to the mirror, there is possibility that the lens base touching the focusing screen release clip to cause the focusing screen falling off...

just my 2 cent.
