| p.1 #4 · Weird dust particles on the Leica sensor?? |
But I donīt know where oil drops (not only the big one in lower right corner of the image) come from in almost new camera. When he looks at the sensor closely under a light, he don't see these particles on the sensor surface. The sensor literally looks perfect when examining under a film loupe.
Which sensor cleaning swabs&fluid would you recommend to use?
Oil comes from the moving parts including the shutter blades, even in brand new cameras.
Film loupes may or may not be adequate for seeing what's on the sensor's surface, that's why you need a dedicated sensor magnifier to know for sure what's actually there. But even with that, some oil/lubricant is very hard to see compared to common dust specks. A wet-cleaning with a solvent like Eclipse will remove all dust and oil spots, though it may take several swabbings.
Everyone here knows my company sells sensor cleaning materials, the only 2 other companies I would recommend are Photographic Solutions and VisibleDust. Stay away from all the rest, they are a complete waste of money.
