on the other hand, the Pentax SuperProgram is also pretty small and can be either shutter or aperture priority.
Canon seemed to into shutter priority for a while, but I don't know canons very well so I'll let somone else dug up specifically which ones. As mentioned at the top, the Canonet was, I also remember the the AE-1 SLR was, but that not quite pocketable (unless you have big pockets.)
