ppolla Posted January 18, 2010 Author Share #61 Posted January 18, 2010 Advertisement (gone after registration) Went to the Leica authorized service this morning, and they cleaned it. Apparently it was dust....which I don't agree but anyway...it is clean now. He said I should not be doing this myself, but that while in guarantee period I shoudl bring to them. He also said, that the "dust" was not on the sensor but on the IR filter that is above the sensor. Very strange....dust that doesn't react on wet method, and that doesn't move while blowing air on it... I hope this chapetr is now closed. I will test it tonight at home.

jaapv Posted January 18, 2010 Share #62 Posted January 18, 2010 Some dust, like pollen, can be very sticky. Or it can be statically charged. Link to post Share on other sites More sharing options...
thrice Posted January 18, 2010 Share #63 Posted January 18, 2010 As per the copper hill website, you should follow your initial clean with another wet clean a couple of days later, as the methanol in the cleaning fluid breaks down any bonds the more stubborn spots may have on your cover glass. Yes you are cleaning the IR filter/coverglass, as the sensor is directly underneath it and sealed. This is the case with every digital camera with interchangeable lenses.

wlaidlaw Posted January 18, 2010 Share #64 Posted January 18, 2010 It sounds as if you were sold a faulty unit. As I said earlier, the LEDs and lens in mine are certainly bright enough to allow the dust to be seen very easily. The Visible Dust sensor loupe is absolutely the best thing in the world for helping to remove splinters. Even tiny metal ones, which hurt the most and are the most difficult to see, spring to sparkling life under the Sensor Loupe. Wilson Link to post Share on other sites More sharing options...

ppolla Posted January 18, 2010 Author Share #66 Posted January 18, 2010 Well......I did a test tonight in the very low light taking an image of my wall...and guess what... The spots are still there...so I am not sure what the Leica certified technician did...! He was busy for 60 minutes...not sure what he did at this time... Unbelievable! It's not about the photo...its about the spots...they became smaller but still very visible...wall is clear and no spots on it... Link to post Share on other sites More sharing options...
250swb Posted January 18, 2010 Share #67 Posted January 18, 2010 Advertisement (gone after registration) The dust is still there...., well a lot of people have said to do it yourself, and I dont' think they were wrong. You give a simple job to somebody else and you become a victim if it doesn't work out. It looks like the technician just shifted some dust around. Eventually you will need to do it yourself, so what better time than the present? On the other hand the dust looks remarkably sharp in the photo. Is the lens stopped down all the way to f16 or f22? You may find you don't see the dust at all if you work at the best apertures for the lens which would be f4 to f5.6. Of course if you need increased DOF this doesn't help except to say that if the dust is over an area of detail it may not show up. Steve Link to post Share on other sites More sharing options...
Rick Posted January 18, 2010 Share #68 Posted January 18, 2010 ppolla... I suspect that what I'm going to write isn't going to help you, but I'm not sure if I have ever had a completely clean sensor for any length of time. I consider LR and CS4 spot healing much the way I used to consider cleaning negatives. Just a fact of life. And, I have to say that a few small dust spots or blobs really don't bother me much because most aren't noticeable and those that are usually can be found in the sky of a pictures and they are a snap to fix. When they eventually add up, they will bother me too, I have a slightly different routine than most: I tend to feel that the glass cover over the sensor is just glass. After I've done the usual test, taking a picture of a light background, stopped down. I then look for the blobs and spots on my computer. Then, I use a strong light and find the blob on the sensor with a pair of surgical loops, like the ones your dentist might use. Once I identify the spot on the sensor I use some isopropyl alcohol or windex or water on a synthetic q-tip (or heaven forbid, my light breath on the sensor) and wipe the spot away. If the fluid leaves any streaks, I lightly polish with another dry q-tip. For the most part, it is just glass, and maybe has an antireflective coating, that should be robust enough to take the fluids mentioned. Find that spot and just wipe it away. I've never damaged a sensor, yet... Link to post Share on other sites More sharing options...
jonoslack Posted January 18, 2010 Share #69 Posted January 18, 2010 I'm with Rick I've never had a completely clean sensor. OnTheOtherHand, when my M9 went for a CleanLubeAdjust recently, the lady who did it said that it was the dirtiest leica she'd ever seen . . . with the cleanest sensor . .. When I got home the sensor wasn't clean anymore! Learn to do it yourself, and learn how many spots matter. all the best Link to post Share on other sites More sharing options...
theendlesshouse Posted January 18, 2010 Share #70 Posted January 18, 2010 Take it back, have it cleaned again, but I would keep the cleaning to a minimum if possible. if you are stil unhappy talk to the dealer who sold it you. Link to post Share on other sites More sharing options...

diogenis Posted January 19, 2010 Share #72 Posted January 19, 2010 I had to go to Cuba for leisure. Therefore before going there, I decided to clean the camera thoroughly before so I don't have to mess with dust. I tried everything: clean, wet wipe everything. After every cleaning I was testing by photographing my white walls f16 oof. Specs went as low as 1-2, My last clean was to hunt down those last dust specs, but I never took another photo. There is no way to kill all dust spots. Usually after a good wiping, your sensor is real clean. Anyway I did my job, packed everything and went to Cuba. I shot some 800 photos, then I fell on my camera hitting it in concrete, camera bumping.. then shot another 400 photos, came back and I realised there was a gust spec. Well you can clean this last spec easily in iphoto, Aperture, LR easy.... Dust specs create a shadow in the sensor, and that is what you see, so you must capture a somewhat light sky or wall that is sufficiently lit, or sheets as Jono says, but at the smallest aperture. Use dust aid platinum, buy a good flash torch to inspect with a cree Led, and you will never lose. Also, don't forget it's not just the sensor glass. It is also the camera dark room, the lenses and surrounding walls, everything in there that can capture dust and release it randomly. And this is where those blowers suck: they just rearrange dust, this is where an arctic butterfly is usefull: in capturing and removing dust Link to post Share on other sites More sharing options...
