I have a a65 as well, its a fine camera also, currently using it as a second camera for some of my assignments. Image quality looks similar, control wise of coz a77 will have the edge(shutter speed of 1/8000, double dials, ISO50 option, vertical grip, direct buttons, extra fine jpeg setting), however slightly limited by its overall sluggish response at this point of time, expecting the release of a more compatible firmware. I also notice on the a65 its has better UI response(Not much lag when you are navigating the menus) compared to 77.
No problem I would be glad to answer to some queries pertaining to the new alphas. However still kudos to qystan for his kind effort of moderating this thread.
