Title: clean dust on sensor-pentax
Post by: mtkang on October 05, 2013, 10:42
hi all,

I got quite a lot of of dust on sensor, which is obvious when smaller apertures.

I am using pentax k-30 which i can flip up the sensor and facing the camera downward and use a blower to blow the sensor. I tried it before, and i found that sometimes the dust is blow into the viewfinder.

what you guys use to clean the sensor? i wonder any tool that 'suck' the dust out instead of blow it.

A rocket blower is all I've ever used on my K20 or the K5 I have now. I try to blow the dust "downwards" away from the  prism. Don't blow too hard. I bought some digipads and fluid for the K20 to give it a wet clean and haven't used them yet on either camera.
I might be just be lucky though.
The dust in the viewfinder is usually on the focusing screen. That should be removable to allow for fitting different screens. Fiddly job, and you can end up with more dust. Only use a blower on that. There are plenty of "how tos" on the net.

Copperhill - that's the answer in one word.

It works, it's safe, it's not expensive in the long run.

Rocket blower might work, canned gas might work, and it might just blow the dust around in there or blow new dust onto the sensor. Oil and grease from the shutter and mirror mechanism, doesn't blow away. For a number of reasons, the bulb first and then Copperhill.
