Pointcolville Posted April 20, 2007 Share #1 Posted April 20, 2007 Advertisement (gone after registration) I'm on my third new M8 in a month. All three arrived with spots (not dust) on the sensor (that is not why I returned the first two; they had other issues). Here is a full crop from shot number 8 from the current camera, dust near the top and a few spots lower down. I am used to cleaning dust from DSLR sensors but have never scrubbed off spots. Searching this forum I saw one post theorizing that the spots are machine oil. I am curious about three things: Will the standard sensor swabs take off the spots? Do the spots recur? And, what are they? Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

bradreiman Posted April 20, 2007 Share #2 Posted April 20, 2007 i use swabs and liquid. very easy and usually only takes one swab accross. when i got my m8 it had grease spots like yours and it took me several swabs. now i rarely need to clean it anymore...b Link to post Share on other sites More sharing options...
marknorton Posted April 20, 2007 Share #3 Posted April 20, 2007 Swabs with an organic solvent like Eclipse will be fine, though I'd get away from the idea of scrubbing: 1. Apply fluid to the swab so that it is damp, not wet 2. Single, slow, deliberate wipe, 3 - 4 seconds 3. Use the swab only once Link to post Share on other sites More sharing options...
ChrisC Posted April 20, 2007 Share #4 Posted April 20, 2007 S......... Eclipse will be fine,....... Mark - Can you buy it in the UK? I have not come across Eclipse here and have been wondering which cleaner I should get. ..................Chris Link to post Share on other sites More sharing options...

marknorton Posted April 20, 2007 Share #6 Posted April 20, 2007 Chris, I think you can get it from warehouse express; I bought mine from MicroTools in Germany as part of some other stuff. Link to post Share on other sites More sharing options...

Pointcolville Posted April 20, 2007 Author Share #9 Posted April 20, 2007 I call it "Sky without interesting detail." It is part of my upcoming "Close eyes/press shutter" exhibit at the Community center for the blind. Link to post Share on other sites More sharing options...
Pointcolville Posted April 21, 2007 Author Share #10 Posted April 21, 2007 Two sensorswabs and eclipse did the trick. The spots looked more formidable than they were. Following guidance here, I did not "scrub," I simply swabbed. Link to post Share on other sites More sharing options...

wlaidlaw Posted April 24, 2007 Share #12 Posted April 24, 2007 It is about three weeks since I cleaned my sensor and knowing that I had been doing quite a lot of lens changing over that period, thought it was time for a sky check. Sure enough the sensor needed a clean. After puffing with a Giotto rocket, I used a swab plus Eclipse, retested and still were a few spots. Re-swabbed with a new swab and still there are a few spots. I am reluctant to keep on at this - any suggestions anyone. I am waiting for my local camera shop to get me some iso-propyl alcohol to replace the Eclipse, which I believe is mainly methyl alcohol.

jaapv Posted April 24, 2007 Share #13 Posted April 24, 2007 I had some spots on the sensor that needed swabbing. Using the Visible Dust sensor cleaning fluid, two swipes per sensor, after blowing of course, and it took me less than 5 minutes to clean both sensors. Spent some five minutes cleaning my Canon after that. Ten minutes in all and everything spic and span. Link to post Share on other sites More sharing options...
wlaidlaw Posted April 24, 2007 Share #14 Posted April 24, 2007 I spoke to the people I get my sensor cleaning stuff from in the UK. He said that if I am like most of the people he sees cleaning a sensor, I will be moving the swab far too quickly over the sensor - probably guilty. He thinks it should take close to 30 secs for each direction. For persistent spots like I had, he said that if you twist the swab just the very tiniest bit from side to side as you are swiping for the first direction swipe but do the return normally, that should remove them. I did one last swab following those instructions to the letter and hey presto - 100% clean sensor. Wilson Link to post Share on other sites More sharing options...
