Originally posted by drewdlephone Just curious... I'm sure this is a noob question. I'm meticulous with my camera equipment... whenever I assemble my bag of goodies for a trip here or there, I pull everything apart and give it a once-over with some air to get rid of dust. This, however, becomes slightly impractical if you're on the go with more than one lens, and need to switch frequently, which would introduce dust anyways. I've been doing this a little more often now that I can play with my Takumar collection.
My question is thus: how much dust on the lenses is too much? And should I be particularly worried if it takes me fifteen seconds to get the first lens off and the second lens on. I'm almost worried about "exposing" the interior of the camera.
You can have an amazing amount of dust on a lens before it becomes a problem. I just don't worry about it.
Dust in the camera is more of a problem, but still not a big deal. If you are using a camera with dust reduction on start up it seems to keep the sensor quite clean, and if you get something stubborn on the sensor, it isn't difficult to blow it off.
