So I see a small insect crawling around in my viewfinder.
Not sure how it got there, since the 7D is pretty well sealed. I guess a few hours at the beach with a 40mm pancake (unsealed) will do it....
Anyway, I thought it was just under the focusing screen, so I figured I'd just follow a replacement guide to remove it (http://www.katzeyeoptics.com/files/install_12.pdf), and give it a clean.
However, once I removed it, I realised it wasn't on the screen at all. I *THINK* I saw the bug, but it seemed to be INSIDE the glass. How can this be?
Is there a pane of glass above the focusing screen? Or is it directly the the pentaprism? Is it possible the bug is on another area of the penta prism and it's just projected onto the face that I can see once I removed the screen?
I'm still curious as to how a bug got up in there any way...I guess it could've entered the mirror chamber via the lens, and then crawled it's way into the prism box.
Is sending it in to a Canon centre my only hope? I really can't afford a repair/service at the moment...
Oh one last question for those that have removed focus screens, in general, or more specifically for the 7D: there's a gold shim frame that acts as a spacer I imagine that sits with the focus screen. I swear I saw two of them when the focus screen dropped down. According to the above link, it seems there's only one? Does anyone know if I'm just mistaken, and I only saw a backing plus the shim? Or if there are two shims, that one should lie on each side of the focus screen, or the metal wire clip pins the screen directly and the shim sits *above* the focus screen?
