What mode is your camera most often in? Why?

Because the first 'automatic' (film) camera I ever owned was actually just an aperture priority mode. It was essentially a manual camera that had the one setting where it would automatically select a shutter speed. Aperture was manual (on the lens) and focus was of course manual. ISO was whatever film I put in, usually 400. I had one 50mm prime most of the time, tho eventually did get a 70-200 zoom...

Ah, those were the days. I still think my film shots were better than anything I've taken digitally, but then I was younger then and my eyes were a lot better
