Eventually it will probably happen even taking every precaution to reduce the chance of dust on the sensor. Did a quick search here at mu43. Bit of info regarding the "copperhill method". Reading HDR thread & the link to Jason Odell review I linked to a commercial site: PhotographicSolutions. Anyone use their Swabs and Eclipse solution? What size swab (17, 20, 24mm) would be the better size for the GF-1 sensor?
I bought this kit for my GF1: Amazon.com: Digital Survival KIT - Sensor Swab Type 2 (w/Eclipse): Camera & Photo {} It worked great!
Here's another thread that might be helpful, although I see rpress has very kindly responded quickly! https://www.mu-43.com/f43/dust-sensor-gf1-help-1346/
Copperhill works. I don't like the Pec pads as they can smear..... Work slowly in 1 direction and you'll be ok.
