I am currently travelling and my sensor has a large bit of gunk on it. I expect it has come from the shutter itself, as it is sticky in nature rather than dust. I am travelling until January 2015 so cannot ship my camera for repair to Olympus - I am on the move constantly from country to country and currently have no home address anyway! I've tried using a rocket blower and a can of compressed air, but it does not shift at all. Is it visible in my photos? Well, you be the judge (link). I've lost a large number of otherwise fine photos because it is not easily removable via Lightroom's Spot Removal. I am trying to compose my photos around it but this is a stop-gap. I am in Egypt from next week and can easily envisage the frustration of losing lots of great tomb photos because of this. Has anyone here personally wet-cleaned their EM-5 sensor? If so, can you explain how you went about it, what tool(s) and methods you used etc. Any help appreciated. Anything information on using something other than Sensor Swabs would be good, simply because they appear to be difficult to source in most places around the world. Thanks!
