Cleaning the focus screen EOS 5D MKII

Not logged on here for a while, so just noticed the site change. Nice...

The other day I had a bit of fluff on the focus screen which a blower removed. Now when I look at the focus screen it has a (tiny) monster spot of something. I tried blowing it off, no joy.

I may have two options, both scare me.

1.Remove the focus screen tweezers latex gloves etc then clean with a lint free cloth/alcohol
2. Use a kit - I have one with sterile paddles and alcohol

Which of the two methods (or any others) can anyone recommend.

I can't actually see the spot of dust on the screen but it irritates intensely when composing a shot. I know it's there and I want to kill it.


The reason I ask for ideas, is that I tried replacing spotty/dirty a focus screen in my old EOS350d, and although it seemed to go back in ok. the red focus lights never seemed to appear again on it.

Any suggestions appreciated.

cleaning the focus screen is no that critical when you take your time and work in a clean environment. The dust may also be in the viewfinder but I can't speak on it. Do you have any pics ?

I'd clean it gently with a kit specific for that

on an other note, cleaning a sensor (usually with a swab) is quite more complex

I personally would leave this to a professional (aka, someone insured).

There's nothing to it. Just be careful that you won't scratch it, or add more dust bunnies onto it.

They sell especial kits and especial swabs. I've used Eclipse, since I don't have any of those kits.

i'd say it's one of those things that if you're a hands-on, technically inclined DIYer, it's totally something you should do yourself.

if you're not, then it's not.
