Use an Arctic Butterfly brush first to pick off the loose dust (otherwise the blower will just puff the stuff somewhere inside the camera) - you don't need to touch the sensor with it, it picks off the dust by static electricity. 2) Test shots 3) If you still have dust blobs, try the blower and follow it up with the Arctic Butterfly again 4) Test shots 5) If you still have the dreaded blobs, try a wet clean - I use VDust Plus fluid and swabs. 6) Test shots again 7) Second wet clean - if necessary There are also fluids specially designed for the removal of oily spots from sensors. A look at the Visible Dust website will show you everything you could ever need for sensor cleaning. I've often found that the first wipe doesn't get rid of everything, but the sensor is generally spick and span after the second. Some people also use an illuminated loupe for finding the dust or grease spots - I think it's a waste of money, because the procedure above gets rid of them without you having to know where they are If I remember rightly, a spot at the top of the frame is at the bottom of the sensor and that left and right are inverted, so if you do have a very stubborn spot, you know where to look for it if need be. Here's part of the cleaning sequence (5 to 7) in pictures: Picture showing distinctive "blobs" http://gallery.leica-users.org/v/DMS/Bits+and+Pieces/Spots.jpg.html "Blob" remaining after the first wet wipe (to the right of the bottom section of the lattice tower, about half way up - probably moved there by the first wipe) http://gallery.leica-users.org/v/DMS/Bits+and+Pieces/First_wipe.jpg.html Clean enough for me http://gallery.leica-users.org/v/DMS/Bits+and+Pieces/second_wipe.jpg.html Cheers Douglas On 05.08.2011 14:52, Kenneth Frazier wrote: > Folks, > > I noticed some dust blobs on several of my landscape shots last night, > checked the lens, it's good, and read up on sensor cleaning. > > > I used my Rocket Blower and tested it this morning with some sky shots. > That seemed to take care of 95% of the problem. > > Question: How often do you M8/M9 users have to clean the sensor, and is > there a better (safer) method? > > TIA > > Ken > -------------------------- > Kenneth Frazier > kennybod at me.com > kennybod at mac.com > > > > > > _______________________________________________ > Leica Users Group. > See http://leica-users.org/mailman/listinfo/lug for more information >
