photolandscape Posted October 26, 2013 Share #1 Posted October 26, 2013 Advertisement (gone after registration) Compared to my M8 or M9 bodies, in the first five months I have had my M240 its sensor seems to attract dust particles like a cow pie attracts flies. I shoot mostly outdoors, and do change lenses frequently. I try to swap lenses quickly and avoid doing so in dusty or windy places, but compared to my previous bodies, I am spending an inordinate amount of time cloning spots and specks. Wondering whether the M and its CMOS sensor produce a static charge that attracts dust particles? Link to post Share on other sites More sharing options...

StephenPatterson Posted October 26, 2013 Share #2 Posted October 26, 2013 Actually I was considering just the opposite today. Even though this Fall season is dry and windy, and China is not exactly the cleanest or most dust free environment, I have gone a couple of months with only a few specs to clone out. I probably change lenses 2 to 3 times per day, although I am careful when doing so, holding the camera body facing down and trying to only change lenses indoors or in a taxi.

Overland Posted October 26, 2013 Share #3 Posted October 26, 2013 ... my M240 its sensor seems to attract dust particles like a cow pie attracts flies ... After half a year of use and repeated procedures of sensor-cleaning, dust in my M was no longer a serious problem. Probably there was internal dirt. Even my M9 and the M Monochrom showed this effect. So have some Patience. Maybe it helps ... Link to post Share on other sites More sharing options...
george + Posted October 26, 2013 Share #4 Posted October 26, 2013 I've been pretty lucky so far. But I try to avoid outside lens changes. Link to post Share on other sites More sharing options...
2wk Posted October 26, 2013 Share #5 Posted October 26, 2013 Yea, my MM was (it seamed) splattering its sensor with oil or something internally. I didn't even change lenses and it was crazy how much the sensor got covered. I sent it back and it came back problem solved. Link to post Share on other sites More sharing options...

I was just thinking that, in comparison to the Monochrom, my M is relatively dust free. Yes, I have to clean the sensor, but not often a wet cleaning. My Monochrom is ridiculous.

250swb Posted October 26, 2013 Share #7 Posted October 26, 2013 Advertisement (gone after registration) All sensors attract dust, in the early stages often it's oil as well. But it calms down, if you clean it. Don't let your M240 become a dominatrix to call you a bad boy for changing lenses when and where you want to. Take charge and clean it when it needs cleaning.

Peter H Posted October 27, 2013 Share #9 Posted October 27, 2013 Like John above, I've been pleased with the fact that my M seems to be relatively dust-free, and after a few months and several thousands of shots and very many (too many) lens-changes both in the house and out in the dirty old world still hasn't needed a sensor clean, unlike my always-specky M9. I don't imagine there's any physical reason for this in terms of the camera design or properties. Just chance, I expect. This may be yet another small reason, less easy to explain than many, why my M makes me happier than my M9. Link to post Share on other sites More sharing options...
Guest borge Posted October 27, 2013 Share #10 Posted October 27, 2013 The M240 should be less prone to sensor dust than the M9/MM. The CMOS sensor requires much less electric power than the CCD, and thus it won't have the same amount of static electricity as the CCD sensor, which again will result in less dust being "sucked on to" the sensor due to the static electricity. Seems logical. Link to post Share on other sites More sharing options...
brill64 Posted October 28, 2013 Share #11 Posted October 28, 2013 every sensor I've owned seems to attract dust equally & it's usually better after vacuuming out my camera bag. Link to post Share on other sites More sharing options...
Ecar Posted October 28, 2013 Share #12 Posted October 28, 2013 My M240 requires much less frequent sensor cleaning than the M8/M9. Link to post Share on other sites More sharing options...
Overgaard Posted October 28, 2013 Share #13 Posted October 28, 2013 A single dust spot in the middle of the sensor during a video take. But that's all, and it blew itself away. No problems with stills. Link to post Share on other sites More sharing options...

albireo_double Posted October 28, 2013 Share #15 Posted October 28, 2013 Well, the sensor in the M240 attracts as much dust as the one in the M9, in my observation so far. And is equally difficult to get rid of, if not even more. I use the sensor clean swabs with Eclipse for wet cleaning, and a rocket blower to get rid of any loose particles.

edwardkaraa Posted March 10, 2014 Share #16 Posted March 10, 2014 Sorry to revive an old thread, but thought I would add my own experience with my 2 weeks old M. When I first got the camera, it showed 5 dust specks, but 2 weeks later and around 250 shots, it is showing over 20 specks. I used just one sensor swab plus, and the specks are down to 2, but a couple of shots later, there are more specks again. I think like others have mentioned that the shutter must be spitting some oil on the sensor, and from my experience with the M9, I think it will take over a 1000 shots to get better.

viramati Posted March 10, 2014 Share #17 Posted March 10, 2014 Well remember you need to keep the lens back, dust caps and lens chamber clear of dust otherwise it will just migrate straight back in again especially if you use LV a lot. I have a blower with a dust filter in it and am always blowing dust off all these areas. It helps Link to post Share on other sites More sharing options...
