"Useless" Dust removal
« on: March 26, 2007, 10:13:09 AM »
I just noticed this post about the (in)effectiveness of the automatic sensor cleaning in most DLSRs.  It's not hugely scientific but the Sony A100 came out with a "useless" rating, which makes me feel a little better about only owning the 5D!

i must admit the shaky sensor thingy didn't remove the dust I had. A rocket air blower worked fine though. Doesn't bother me really, as long as the anti shake works I'll use the blower to clean things up inside the camera.

I always suspected vibrating the sensor about didn't do anything of note. This proves it to me all the more. Even the Olympus anti-dust feature looks pretty pointless. It's all or nothing to me, you see. Even if 80% of dust is removed it's still not much good, you've got to clean it to near 100%.

Admittedly, though, they dusted those sensors to the extreme. I mean, it looks like they left the camera open in a sawmill or tipped a bag of flour inside. In reality a few spots here and there is what you get. :)
