Ok, I'm moving to a 20D from my 10D for various reasons, (one of which that since the release of the 30D, secondhand 20D prices have fallen
).
Anyway - I was wondering - on the 10D there is a switch to lock the control dial on the back. In the dpreview review of the 20D (http://www.dpreview.com/reviews/canoneos20d/page3.asp
) it states
"Canon has combined the power switch and the quick control dial lock to a single switch."
Surely, that just means the control dial is locked when the camera is turned off? Well, it would be anyway, cos it's turned off, so the dial would do nothing anyway, or am I being simple, and it's a 3 position switch?
