I used this guide to fix my 600D (Rebel T3i), and it worked like a charm.
The middle lens of my viewfinder had popped out of its plastic holder. it is now back in place, thanks to this guide.
I have added a couple of marker, to make it just that little bit easier to spot the screws and ribbon cables.
Thanks again!
I used this guide to fix my 600D, and it also worked like a charm.
The front lens of my viewfinder (the one closest to the eyepiece) has popped out of its plastic holder.
Thank you so much for this guide. The viewfinder lens of my 1100D came loose some days ago and this guide served perfectly.
Just a heads-up to the newbies like me: Take a lot of care with the focusing screen (the one with the focus points printed on it), I tried to clean it and ruined it. Fortunately, the replacement is not expensive, but still, better not touching it with anything.
