Thanks for the tutorial!

How much dust fell into the body cavity during this procedure? Did any stubborn ones end up on the sensor/filter screen?

How would you measure it? :)

Seriously, it doesn't take much longer to change out the screen than it does to change a lens. Besides, the mirror and the shutter are still covering the sensor during the whoe procedure.

You mean you don't have a "dustometer? :p

Even thought the mirror and shutter would protect the sensor filter at that point in time, any dust that gets inside the body cavity could eventually wind up on the sensor filter with all the flapping and moving parts that happen when capturing an image.

I guess one should treat the focus screen operation just like a lens change--be in a conducive environment and take precautions.

Plus, any dust that does settle in is going to be the kind that the blower blows right out of there.

Or, you could just change lenses (or screens) and not worry about it too much. :)

Wouldn't distilled water be preferable? :-)

Na, not necessary. The little screen inside the faucet catches all the big stuff anyway.:lol:

I use carbinated water. I figure the bubbles help loosen the tough stuff. :D

The Katz Eye looks nice, but that's really too expensive unless you're used to using split image. I'm liking my Ef-S screen, and have since I first installed it on the first day I received the 40D. Maybe in the future I'll get the Ef-D, but I'm thinking that's more suited for a full frame body like a 5D.

71SBeetle, thank you for sharing your quick and easy cleaning technique. If the 50D is sealed better like they say, draining is going to be a big issue. Maybe that's another reason to sit out this round.

Haha, i was actually thinking the reverse...waiting to get the precision matte screen for when I got a FF cam...but I got the EF-S for my 40D today, and I'm liking it
