Thanks ,i am not sure the G20 has enough improvements over the G10 to worry much,I shall probobly go with the XA10 hopefully.i don't actually recall seeing volume control of any kind on the g10 but it wouldn't surprise me that it has some LCD type of control. however, if you've ever done much shooting you know that very quickly sound can change from one level to another and a dial is a real PLUS
as far as formats i think this is what i saw . . 1920 x 1080 at 60i, 30p, 24p and there was one other i believe. there might have been more but that was all that i was interested in for our purposes. hope that helps. perhaps another g10 - xa10 user could jump in here. as i say, ive only had them in my hands to work with a few times, the g10 for like 3 days, and therein i am waiting to see if there will be a xa20 or whether to just go ahead and get the xa10's once i hear all the reviews of the g20 and see if the wait would even be worth considering.![]()
