Why would I want to do this ? I hear you ask, well after five years of hard graft with this camera and trying in the last three years to clean the dust and rubbish that accumulates out of it. Not necessarily the right way. I found I had made little scratches that were even more annoying than the original dust and hairs that seem to find their way into this very, apparently, tightly sealed area!
Next Question? Why so long before doing this? well for a long time Canon have been saying that if you do anything to your camera in invalidates their warranty. Secondly that you couldn’t change the focusing screen on a Canon 70D, and that really didn’t make sense as had I sent it to Canon for changing, they could do it!
So as I do from time to time, I look on the internet and see if anyone has found a way to do this themselves. Imagine my delight when I saw a video on You Tube of a Canon 70d Focus screen being changed, step by step. By a guy called JS. Not that hard is it?
Well before you even think about embarking on this type of activity there is something you need to think about. The quality of what you are putting back into your camera.
So I trawled the internet again and found DHcamera an American camera spares and repairs company selling spares. Great and they would post to the UK! Even better, because although I am currently living in Thailand it is still easier for me to get things sent via the UK.
So via the UK , Via my Daughter, this arrived today. It took bout two weeks t arrive in the UK and then another 7 days to get to me.
So armed with my blower, my small screwdriver set, rubber gloves, tweezers and spot lamp, i started the process of dismantling the inside front of my 70D. As per video. Just so you know, I watched the video several times until I was happy with what order i was to dismantle and reassemble in. I still had my laptop on standby , video poised at any point to help if i got stuck.
All went very smoothly and about half an hour later, although it felt like longer, I had a nice new shiny, blemish free focusing screen back in my viewfinder, and oh what a joy! No annoying little bits of dust and debris, and definitely no Scratches!
This is the Screen…….
and the little plastic tool is for clasping the little protruding leg to handle it by so you don’t damage it again on the way in!
