Review: Dust removal systems / sensor cleaning

"Sensor cleaning is becoming a standard feature on modern digital SLR cameras.

While the manufacturers may use different techniques to get rid of the dust from

the image sensor, they all promise clean, dust free images. Do they all work

equally well? Can we throw our air blower away?"

"We had four different cameras from four different manufacturers: Canon

EOS-400D, Olympus E-300, Pentax K10D and Sony Alpha A100."

Interesting test, perhaps manufacturers should start building blowers into their cameras...

 

the Olympus results look a bit dubious as they look to be shot at a larger aperture than the rest?

I guess dust removal won't get factored into my decision to buy my next camera.

Olypmpus probably had the same aperture. The author addressed the dubious looking dust. He claims the smaller sensor and possbily the larger separation distance between the dust layer and the sensor might be the reason why the dust particles more less aparent on this body.

Auto Sensor-cleaning, schmensor-cleaning...

 

It'll never beat the low tech approach, e.g., Visible Dust Brush system, that is transportable across all camera manufacturers.

 

And as for in-body I.S. (totally a consumer level gimmick anyway), Canon is backing all the way the obviously better lens-based I.S. system (and I'd bet money Nikon will stay the course with their lens V.R. system).
