Anatomically correct way of cleaning the D30's innards

[Luc Bouvrette]

I know, been covered before, but let's look at it anatomically speaking. Here's a diagram of a typical D30:



Now, the 64 000 $ question about dust cleaning. Aside from the CMOS sensor, what part should DEFINITELY not be cleaned by anything other than pure pressurized air-although from a hand pump-ette or your friendly auto-body's blaster? I know this is still debated, I still go for the rubber enema foot pump... ;-)

Don't I risk blowing dust around closer to the sensor if I air clean the mirror and focusing screen (right underneath the pentaprism) by air or could they simply be both dry cleaned by, let's say, an Optex lenspen ? I feel that blowing air in there mostly causes it to mill around and eventually reach the sensor area.

Whatcha guys think?

Thanks!

Luc, I wondered about just spreading that stuff around in there and after seeing the diagram it looks much worse. I think we should design a vaccum attachment that would have a Canon lens mount on the end of the nozzle. ;^)

I'm thinking (am on the waiting list for the 1D), only thinking, you have to start with clean air. This means you gotta make where you are working on this beast (no offense) a "clean room" as much as possible. So I'm going to purchase a negative ion generator from sharper image. It's called the ionic breeze and it can condition the room by causing all the airborn dust to just drop out of the air (no joke). I've used one of these before. It works.

You do a bit of pumping (away from the camera) with whatever blower you are going to use, to let it "breathe" out the dust that's in it, and to let it inhale the dust free air, and then, with the lens mount facing the floor (so dust can obey the gravity rules), you give it a soft blast.

Then pour yourself a mug old-fashioned root beer for a job well done.

Seriously, everything I've read on this says you gotta do a lot of cleaning of the outside around the mount, and of the part of the lens which sticks into the camera, because if those areas aren't also clean, you're wasting your time. NOT sure if this as big an issue with a CMOS sensor as it is with a CCD.

my opinion, of course, and my .02

I think I'll stick to my cotton buds!

LMAO

Thanks, I needed that!
