[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I used my M8 for two years and about 9000 frames with no difficulties with routine cleans. This is nothing more than a procedural hiccup. I've found one brand and method that's perfect for me. It doesn't do to stress over this stuff! I certainly wouldn't recommend that anyone not use their M or consider that the need for sensor cleaning should deter anyone from using ANY digital camera with interchangeable lenses. My personal prefernce is for Leica's sensor and its very precise calibration within the body rather than any vibrating system. Your cyclic rate may vary, people ;-) Cheers Geoff http://www.pbase.com/hoppyman On 3 March 2010 15:55, Jim Nichols <jhnichols at lighttube.net> wrote: > Much as I envy the M8/M9 users, these recent cleaning tales make me more > pleased every day that I am using a couple of Oly E-thingies.
