I've had my 1D for 4 or 5 years now and my 1D.2 for almost 2 years. I have never done any sensor cleaning other than a hand blower. I think L glass helps keep the dust out more than the body does. That rubber gasket on the L lenses' mount is what helps.

I shoot mostly wide open which helps to minimize any dust and it's usually when I'm off hiking taking pictures at f/16 or f/22 that I come back and realize I've got dust. Then a few blows takes care of it.

I take no great care in changing lenses and even had my 1D fall lens mount first, no lens attached, into the sand at the Tempe AVP Open one year. I had just changed lenses and apparently didn't get it on all the way. It was at the end of the day so I just went home and blew it out and had no problems with dust.

But, I'm sure I'm the exception.

Can I ask those of you using DSLRs how often you are finding it necessary to clean the sensor? After only week of (fairly heavy) use, I just had my first instance of sensor dust. The manual-recommended method with the rubber bulb blower solved it, but I just wonder how much I need to overhaul my lens-changing technique, or if this is a fairly common occurrence no matter how careful one is. Do the 1 series DSLRs have less of a problem with sensor dust?

TIA
