My wife has rheumatoid arthritis and an associated lung disease and can no longer handle her D300 and would like a good point and shoot. Something with a decent zoom, excellent IQ, IS I suppose if possible and something which doesn't require 10 seconds to shoot the image after you press the shutter button. Is there anything specifically you folks might recommend? It will be for casual landscapes, people and perhaps a flower of neat pile of rocks along the shore some times...nothing horribly high tech. Any recommendation would be greatly appreciated. Price isn't a huge concern.
