Chasseurs d'Images magazine has an interesting article this month. As most people can't read French I thought I might share it with you.

CdI tested dust-removal mechanisms available in different DSLR's. They deliberately exposed the camera to a dusty atmosphere and and checked to see how well they did:

- Olympus E series did very well with it's special high-frequency shaker
- Canon 400D/XTi was fairly effective at avoiding dust sticking on the sensor, but once it was there, the shaker was only moderately effective at getting it off
- Sony and Pentax systems with a low-frequency shaker were not very effective at all
- Nikon and Canon software solutions (Capture NX and Digital Photo Pro) were very effective

Bottom line = in most cases a physical clean is still necessary from time to time.

Anybody got any thoughts on this?
