I'd put program mode on my list of over-rated features. Whenever I've tried it, I invariably find myself becoming frustrated and putting it back to Av or M. It feels a little strange saying that, because one of my favourite take-anywhere cameras is the Yashica T5, which only has program mode.
Autofocus used to be on my ORF list, until I bought a Contax N1 ; I like the Contax system of five AF points strategically placed in rule-of-thirds positions, and the thumb-operated joystick control to switch from one to another (I prefer it, to my slight surprise, to the technologically slicker eye-operated focus point selection on my Canon EOS 5/A2). I suppose my view on autofocus with this camera is influenced by how stunningly beautiful and sleek it is. I ought to add that most of my photographic interests don't need autofocus, so in many respects, it solves problems I don't particularly have.
Like a few members here, I was brought up in an era when the over-rated feature list probably only had double-exposure prevention in it, so manual-everything is default mode for me. I've a camera that has more ORFs than I know what to do with : modes for taking pictures of fireworks, taking pictures of fish tanks, taking pictures of people with ice creams at the beach, that sort of thing.
There are times when I've had enough of everything, and take out my old Box Brownie No.2 Model F. (Even that's got a swing-out lens for portraits!)
