Such widely different viewpoints expressed and different experiences reported. Leica M's of course don't have lots of the technology the big manufacturers use. We all know that. Fine by this amateur. Others may prefer more of course. I appreciate the approach of best possible optical path, absolute minimum of material in front of the photo sites. I don't do any of these special precautions. My camera always has a lens mounted so I can use it immediately. I just pull the next lens from the bag and take off its rear cap, twist the mounted one off and swap. A couple of times a year I spend 10-15 minutes to brush off the sensor then use one or two wet swabs. If the air was full of dust or blown sand/spray then I wouldn't. No one is paying me to get those shots. I don't use my cameras hard in hostile environments. Incidentally Nikon just told me that my D600 may develop excessive spots on the sensor and that I should return it to a service agent if so! Fancy that. cheers Geoff On 25/03/2013, at 6:46, Cedric Agie <cedric.agie at gmail.com> wrote: > There must be a problem of stattic electricity, certainly with a new > camera containig electronics.
