I'm sorry for creating new thread and this topic was discussed lots of time, but now I want to look at it from other perspective. Now I have some dust on sensor and I have Pentax O-ICK1 and Giottos Rocket Blower. I get dust very frequently (all time when use tele lenses) so I think its not very good to touch sensor every two weeks. Now I'm considering to use Giottos, but I'm concerned about the new dust. Somehow I think that I will blow more dust inside than blow out from sensor. Am I wrong ? Maybe you have some special technique of blowing out dust with Giottos ? Please share it with me and maybe with other members
Originally posted by foxglove I have a rocket blower, and it does a pretty good job at keeping the dust down so I don't have to wet-clean the sensor that often.
I generally face the camera more or less lens opening down and puff up at a slight angle, theory being that it'll dislodge the dust which will then fall out of the camera. So far it seems to work for me! I predict that you'll get every possible opinion on this...

What Julie said.
Use the sensor shaker first. Followed by the blower. You can buy a brush (some use a soft makeup brush) to dislodge some of the more static dust, using the same method as the blower. Then use the I-OCK1. If none of those work, then it's time for a wet clean (I use the sensor swabs and Eclips2).
There is one here who will swear by Canned air. If you use it, make sure to give a test blast to make sure it doesn't expel any propellant or other moisture before aiming it at your sensor.
Keep your lens mounts clean as well as the rear Caps. Clean out the mirror box once in awhile to help keep migrating dust down.
The last time I did a wet clean was on my first K10d, over 2 years ago. I found that the K20d and the K7 are far less prone to holding on to dust for dear life.
Good luck..
