Yes, most Canon stuff is shutter priority, the AV-1 was the oddball at the time The A-1 and Program offer AV, TV and P. I really prefer the older fully mechanical bodies but perhaps that's just me... my AE-1's battery crapped out on me today while my FTbN kept on shooting, just something to remember with the A and T-series: the shutters need battery power. Still very easy to buy in Lithium and Alkaline 6V but keep a spare in your pocket to warm up in this winter, why didn't I remember that this morning???
