Lately it's been a Nikon F50 with 50mm & 28mm af-d lenses and a Minolta XG 1 with 50mm f/2 Rokkor.
Both have good size viewfinders and accurate metering. Neither are top of the range cameras (quite the opposite) but they both do what I need them to do which is mostly nothing tricky, just walkabout stuff.
It's odd but I do have better specified cameras (F3, F100) yet rarely use them as they seem 'too good' to use on the sort of pics I mostly take. No I don't understand it either!
