( not just an addition > To aperture priority) Trick question since by your wording you exclude cameras that have manual mode in addition to auto. You don't get to do that. Aperture preferred was technically easier to do, which was why it was done. It was easier at the time to control the shutter electronically than it was to stop down the lens mechanically. More pictures are compromised by slow shutter speeds than too little or too much depth of field, so you cannot make a case that depth of field control is more critical than blurry pictures from slow shutter speeds. So a few cameras that offered shutter preferred but not aperture preferred automatic: Note that they all offered manual exposure control as well, they were not crippled meter cameras like the Pentax MV and it's ilk, or the Nikon EM, or Canon T-50. The Mamiya/Sekor Auto XTL had shutter preferred auto, as did the Canon AE-1 (arguably the most popular SLR of it's day), as well as the earlier EX EE and EX Auto The Nikon F2s was able to be adapted to shutter preferred automatic. With the Canon F1, if you bought a particular viewfinder, then you got aperture preferred auto, if you bought a motor drive, you got shutter preferred auto, so it was possible to have an F1 with shutter preferred auto but not aperture preferred auto.
