my canon t70 doesn't have aperture priority mode (i really don't know why) and that's been annoying me since i have a lens that does f/1.2 now and i want to do f/1.2 but then I realized since the t70 does have safety shift in shutter priority mode that setting it to Tv and maximum shutter speed is actually equivalent to setting it to Av and maximum aperture (which is 90% of the reason I ever use Av mode anyways)
the more i shoot around on the t70 the more i'm getting convinced that the canon a-1 being good was a complete accident and canon didn't make a microprocessor camera that was good on purpose until the t90
