Took my 40d into a very reputable camera repair shop in Seattle to have sensor cleaned. When I picked up the camera it was all wraped up in a plastic bag. They informed me that I should always keep the camera in a large zip lock bag to help keep dust out, even while stored inside my gear backpack. My concern with this suggestion is that moisture or condensation would occur and really cause problems. What is your thinking on this topic zip lock bag plus gear bag or just gear bag or some other method of storage to help reduce dust problem.
Thanks
