| I recently bought the rocket air blower to clean dust off my sensor glass. I didn't know that you're supposed to activate mirror lock before using it. Is it damaging that I've been blowing it inside the camera without the mirror lock? What are my risks here? thanks |

| Can't answer your question, I just use the built-in sensor cleaner. |

| Without locking up the mirror all you're doing is blowing dust off the mirror. |

Virtually none..
Two things - make sure you have a fully charged battery (you don't want the thing going dead and slamming the mirror down on the blower, and two, don't actually touch anything inside the camera..
Other than that, you're pretty much good to go..
Oh - FWIW, I've used much higher pressure air sources, and they didn't do much.. I've found the Copperhill method is about the only thing a person can do in the battle against sensor dust...

Visible Dust products are another option. They have different tools for different methods.
The blower is great for blowing stuff off that isn't stuck. You need something like Copper Hill or Visible Dust to get the stubborn stuff off the sensor.
Even with the auto clean available on a lot of cameras now you'd be surprised at how dirty your sensor is. |

| But you can SEE the sensor dirt, if not ttl then on images. I clean my sensor during each photo session, and (so far) no regular specks of crap turning up on images. Once I had to use a blower to get some cat hair off sensor. Made sure camera completely vertical, no lens on it, then used mirror lockup/blower/auto sensor clean. NOTHING. Eh wala. |

As discussed before...you were just blowing the mirror.
Are you sure you have sensor dust? Did you try the auto cleaner on the d90? |

Just out of curiousity, have you ever really stopped down (say f/28 or so) and taken a picture of something solid colored and bright? Then knock up that contrast in post... it'll show every speck of anything on your sensor...
I try to wet clean my sensors once a month or so,, still they have dust on them, in the desert it's just a fact of life that we try to deal with the best we can.. |

If you're shooting wide open or close to it you're images won't show much if anything at all. Where you will see it is at very small apertures. Try shooting a pinhole image (aperture of ~f100+). |

| ....and...Don't sweat a little sensor dust. I used to FREAK OUT and wet clean my sensor every time I "thought" I saw a speck on a photo. Just use your built in cleaner unless it is REALLY bad. |
