Sounds like dust, get a rocket blower and blow it out. You can rarely see the dust on a sensor, but it will show up at smaller apertures on screen. Don't use compressed air or blow at it with your mouth as both container moisture and you risk making things worse than they are. My old 7D never went for a cleaning and never showed dust, just regular blow outs with a rocket blower.

Done that, and if you hold the sensor at the right angle you absolutely can see dust on the sensor. Granted, given the size of what's showing up, I might give it another shot, but the spots aren't large like the one spot that was on my 7D not too long ago.

I can take out a 5DII sensor, clean it, and put it back in in under 15 minutes. quite easy. But that's a bit of an extreme, I've never had to do it but it is quite easy. 16 screws I think...

I think? Meaning it starts with 18 and you always end up only putting 16 back in? tongue.gif Just kidding sir..

I'm gonna try to take a closer look to see if I can see anything, and give it one more good cleaning with the rocket blower to see if it gets any better. I remembered when I saw the dot on my 7D showing up in my long exposures and I was mortified, but when I opened it up I could physically see the speck of dust and blew it out.

Small amounts of moisture can make dust motes stick to the sensor. I bought one of these kits and it took care of the dust motes which wouldn't dislodge. Cheap and easy.

Only available at the store apparently.. else I'd give it a shot. If moisture could be doing that, what if I left the body upside down on a silica packet for a bit to see if I can get whatever it is to dry out and then try to blow it out again?

Edited to add: Reaper, you selling a 50L on CL Boston for $600 at the moment? Because if you're not and it's legit I'm buying it..

Lol, I feel weird having never had a dust problem. Seems like Canon could come up with something comparable to Olympus's system, but apparently not.

Canon has the same thing, high frequency sensor shake, maybe Olympus shakes a bit harder.
