Canon A70 How do I expose dust shutter mechanism to clean?

Hi

The dust shutter gates/barriers get stuck.
I think it is probably some dirt and would like to remove the front plate which covers the
mechanism.

Can anybody help on how the front is opened?

Thanks

It's a time consuming job and not easy. Unless you are a serious
hobbyist, "if it ain't broke (or it still partially works), don't fix
it". If you have the time, a 000 screwdriver, and a lot of confidence
this may help.

Thanks.

I have looked at the exploded diagrams.

Do you know if the front barrel cup (item 1 on page 4) is pressed in and can be prised out or does
it have a thread and need to be unscrewed?

I would not like to dismantle the whole camera and approach from the rear if I can clean the
mechanism from the front.

Thanks

Sorry, I don't know how that part is attached. It looks too thin to have
threads. My guess is it is either stuck on with double stick tape or
snapped on.

Try a little compressed air first. Then cycle it on/off a few times.

I have had some success but there must be a piece of dirt that gets blown around rather than blown
out. Camera operates through about 6 cycles and then the shutter either doesn't open fully or
doesn't close. Tried blowing out in all positions.

I'll keep trying.

Hi,
I do not have any problem with my A60, and can't help Roger,
but I am happy to have this pdf in case.
Thank you Tom.

PS: good luck to you Roger
