Canon EOS 30DPosted By Dan Avnet |
Hi Greg,
The sensor cleaning function on the 20D just locks the mirror up so you can gently with a bulb blower air the dust away from the sensor. Basically a 20D with nice tweaks and I've heard a lower price. I think it's a bargin. But for astro work the 20Da is the way to go IMHO. Looking to get one soon myself.
Best,
Dan
