Sugeestions/comments on Mamiya 645 Pro

  1. I'm looking into stepping up to medium format, I have done some research and would like to buy a 645 pro, I dont know what prism is best for the money, the AE that is being sold with a package at a good price, or spend a little more and purchase their Pro AE with TTL, can some one give some advice. Thanks...
  2. As far as I know, the AE prism that comes with the SV pack is a cheap prism. You lose about 11/2 or 2 stop. Better opt for the true PRO AE TTL. I uses an ETRSi myself as I found that I needed the shutter leaf lenses. If you decided to use a shutter lenses for the 645 Pro, it will cost you considerably more than the lens for ETRSi. Just my 2cents.
  3. As far as I know, the prism in the SV pack is not a glass prism.
    It is composed of mirrors, just like the "prisms" in cheap 35mm
    SLR cameras. The only advantage of such a construction is the
    reduced weight.
    The SV prism does not have built-in spot metering and exposure compensation. It has center-weighted metering and aperture-priority
    exposure control, but you can4t see the selected exposure time
    in the view-finder.
    If you can afford it, go for the more expensive AE prism finder
