I just purchased a brand new 5D2 and noticed a small dark spot on all my pictures. Anyone know what it might be? Is it just a dusk particle that can be easily removed or is it a flaw of some kind? Does it need to go back to Canon to fix?

The first image was shot using a 17-40L at f/8. The 2nd is the same but at f/16

Thanks for any help.

Dust or excess mechanical lubricant.

Most likely dust on the sensor.

I'll vote for something on the sensor - probably dust or maybe a bit of mirror lubricant.
Don't worry about it.
It won't be the last bit of grot you get on your sensor.

Yep, just a bit of crud on your sensor, nothing to worry about. They throw some in free with every purchase, all my DSLRs had some when new.

LOL, if one dust bunny is driving you crazy, you are going to either suffer OCD and become very well practised in sensor cleaning, or end up in an asylum. :lol:

Both of my T2i's came with a nice gift thrown in. A quick mirror lockup, blow with a rocket air blower and bam, just like brand new, except without dust.

Try a air blower (Giottos AA1910 Medium Rocket Air Blaster) like the type you can get at photoshop first and if it does not come off then try the wet sensor swab method; make sure you get the ones for the full size sensor.
