I flipped open the flip mirror (properly of course) on the 5D MkII and CAREFULLY wiped over it with Bintel's UHTC cleaning fluid. IT improved it SOMEWHAT, but still some mote artifacts in photos (NOT apparent during day shots - only extreme contrast shots).
So, go at it again with thefluid, or is there a better way? I am VERY reluctant cleaning the sensor platen /IR filter...
Opinions and suggestions HIGHLY appreciated,as I am tired of having to stamp out the motes in photoshop  |
I had a similar problem with my 450D. Only noticed it when imaging the Venus transit. There were a few "extra" sunspots. It took me a few goes with the fluid to clean the IR filter/sensor cover. I suspect that microscopic water droplets had got in at some stage and some mould spores had grown. I always try to avoid touching glass surfaces with anything ,but what else can you do?
