Fuji GA645 is the answer to what you seek. i, w, or Zi variants are avaialble. I have all 3. You can think of them as the Stylus Epic of the Medium Format world - light, fast to deploy and operate, and deadly sharp lenses. Built in metering, super accurate autofocus even in very dim light (use an advanced dual active IR/passive rangefinder system), and data imprinting on film edge are all benefits. Best of all is the price - around 500usd.
The 645i has a fixed 35mm equiv. FOV lens, the w a 28mm equiv FOV, and the Zi a 35-55mm equiv. zoom lens.
Biggest drawback for me is the max shutter speed is only 2 seconds, so no small aperture, long exposures in dim light on a tripod.
