There is a rift running through the photographing community, a rift between amateurs and press photographers on the one hand, who want a picture perfectly sharp, with colours as natural as possible and maximum depth of focus. Others, let's call them the artists, want to control every aspect of their exposure, and may be more open to post-production manipulation. Both, of course, have certain priorities in common. Fast start-up times and high exposure frequencies are on that wishlist.
This rift is not reflected in the current marketing strategies for cameras. Models are not sold separately to the two groups, and cameras come with a plethora of modes, an easy-to-use all-manual one often being absent. And there are other niceties that I can't seem to find - how about, for instance, an SLR camera whose lens automatically opens when you pick it up (or not if you switched off that feature)?
