I picked up my 7D a few months after you purchased yours.. My sensor is just as clean. I've never really had any dust issues. This is a testament to the sensor cleaning system. When I had my 10D, I had to wet swab the sensor once every four months on average. I've never touched the 7D sensor.

Yes, you do have some specks as seen in the shot by MakisM1 above. To get the screen he has shown you, use auto-levels in Photoshop. You might want to try something like the Rocket Blower to try blowing off the specks, but if you can't see them at f/32, then you probably can wait on doing a more thorough cleaning.

In some cases you can use the Equalize option to really bring these out too. :)

What seems odd to me is how there seems to be layers of exposure from the f32 shot, almost like the cleaning was too aggressive and layers of the AA filter or sensor was removed? On a properly cleaned sensor, you might get some dust bunnies, especially around the edges if you aren't careful, but I never get those graduated sections.

I think the 'layers' that we see have to do with how the 'Equalize' boosts different values of contrast ;)

Thanks, I only used the camera's sensor cleaning. Never had it cleaned with 3+ years of ownership.

It's not too bad, I wished mine was that clean now. Rocket Blower does wonders for you lens and mirror.

I suggest you leave it alone until you find there's something that you can see in a shot. Then do something about it. Leave good enough alone. Just my two cents

I agree, wait until you actually see them in a normal sky shot
