the dark black spots are likely to be oil spots, but the white ones looks to be a symptom of sensor coating surface peeling off. it will usually look like a spit spot when you look close up, but this many....did you recently do a series of very long exposure shots?

Did you do a wet cleaning of your sensor? It looks like bubbles that were build when you are using to much cleaning liquid. When the liquid drys then you can see the edges of these bubbles as white rings on the sensor. Try to get a sensor magnifier. I think you will see the white rings. To clean the sensor use a wet cleaning swab like the ones of visible dust but use not so much cleaning liquid.

Bernd hit it, I think. To add, Eclipse2 is prone to levee a hard to remove white deposit when used in excess, especially if you use an older bottle. If I were you I would have a good firm do a professional sensor clean before panicking.

It looks to me like someone sneezed on the sensor :D

 

But seriously, I think this could be tiny oil droplets, either from the shutter or from the bulb blower (some are internally oil coated to keep the rubber from cracking).

Mysterious indeed. It triggers my imagination. Your username makes me think of Thailand. Just my guess: Could it simply be due to condensation? Did you take the camera out in the heat from an air conditioned room or car and maybe also change lens before letting the camera adjust to the heat? If so, the spots should go away once the body has dried out.

 

An intriguing mystery. Please let us know when you find the correct answer!

so i took the camera to the dealer and the problem is the coating on the sensor is peeling off. so sensor replacement is needed under warranty...

 

Thank you for posting back Thanakorn. This is the second case of sensor coating peeling off I heard about this week. Doesn't look good.

like i said. how do i know? my M9P is on vacation to Solms right now for sensor replacement from this symptom.

So this is the 3rd case I hear of, and they're all in Bangkok. Does anyone know the cause of this peeling? Is it caused by hot and humid climates?

a friend of mine has his sensor replaced twice now, but he lives in New Zealand. from what i've gathered, it is due to long exposure shots causing the CCD to heat up beyond the threshold of the coating (not sure if THIS actually is the cause, but i also suspected so since i do a lot of long exposure shots too)

If indeed that is the reason, no wonder Leica is limiting the long exposure time on the new M.

The M is also a lot noisier on long shots, at the limit you can see more noise than on the M9 at the same exposure time.

 

A shame really, it's the only thing that's not improved.

 

I also do a reasonable of long exposure, and often several shots in a row, but I'd not had the sensor coating peeling problem on my M9 (yet).
