marcoma Posted October 5, 2009 Share #1 Posted October 5, 2009 Advertisement (gone after registration) Hi, So I decided (with the help of this forum) to get the M8.2 with a 28 Elmarit (ASPH), 35 Cron ASPH and a Zeiss 50/1.5 - Not sure if I should keep the 28 as I don't see that much difference between it and the 35 but that's a different topic. Murphy didn't forget about me and after about 100 frames I noticed little blobs on ALL the images on the same spot... the lenses (dust on the back glass) were easily taken care of, but I noticed a large 'Blob' of dark matter (about 1mm in diameter) on the sensor... a good puff or careful brush movements didn't do anything to it... in fact, at first I thought the sensor had scratches on the surface... but when (in desperation) I used more force and a microfibre cloth, I could actually rub it off and it has been fine ever since. So here the question: Since it was a new camera, could it have been oil spilled from the shutter release? And what is the best way to clean lenses and sensor? I am assuming dust is relatively easy brushed off, but should I use a microfibre cloth, a light brush, air (not compressed in a can... I know)? What is the best long term approach as I don't want to rub off any coatings... I'm not worried about buying a new filter every once in a while if I rub of the coating there... but several thousand dollar lenses are a different matter... Experiences, suggestions, ideas?

Nicoleica Posted October 5, 2009 Share #2 Posted October 5, 2009 After recovering from the shock of reading that you had cleaned your sensor vigorously with a microfiber cloth, might I suggest a more gentle method in future? There are several brands of cleaning kits available that use a wet swab system. Other readers will suggest specific brands, but most are quite effective. Please try not to rub your sensor with a cloth, or even touch it with a brush unless you absolutely have too. They are quite delicate, and easy to damage. If a puff of air from a blower doesn't remove all debris, then try something like the Arctic Butterfly, which employs a slight static charge to attract the dust. If that fails, then a wet cleaning is required. Try to always change lenses with the camera pointing down, this reduces the change of dust falling into the camera. Don't leave lenses or the camera without rear/body caps in place. And ensure that the camera is switched off before changing lenses. It is also important to ensure that your lenses are clean, as these are a great way to transport dirt and dust into the camera if you are not careful. (Don't keep bare lenses or lens caps in your pocket for example.) With a new camera, spots of oil from the shutter mechanism do seem to be quite common, but this should ease after a short while, as any excess lubricant soon makes a bid for freedom.

marcoma Posted October 5, 2009 Author Share #4 Posted October 5, 2009 Ahh... the 'search' would have been my friend again - apologies I wasn't maybe as vigorous as it might have come across with the sensor - but it did need a few swipes across it at more pressure than I'd have liked initially... had another 400 or so shots after it and it seems pretty perfect... one of the things I found on finding little spots in the first place is to expose a frame without a lens attached... it just produces a whitish / grey picture that is great for going over on a big monitor if no pure white space (white wall, paper etc.) is available in the first place. Thanks for all the suggestions... I am sometimes even a bit too delicate when it comes to sensor cleaning, but I never experienced those spots on the sensor with my DSLRs - at least not to the point where I needed to 'rub' instead of just blow or swipe... Thanks again for the suggestions... I'll leave the Microfibre for the Lenses... Link to post Share on other sites More sharing options...
