I recently bought the first camera I've ever had with an "A" on the shutter speed dial, and I'm sold. It's f/4 and A most of the time, except where it's f1.4 and A. :-) Like some of the others, I've been doing this for 50+ years, but when I look at my recent film compared with 30 years ago. . . well, the camera is doing a lot better than I did. And I was such a Luddite back then!
