Got to play with a working Alphatron EVF last night. There are still a few bugs in the firmware to be ironed out, but boy oh boy, what an improvement over the Cineroid or Zacutto. If you think the viewfinder on an EX3 is good, wait till you look into one of these. The resolution is right up there, crisp clear images that can be focussed without the need for a ton of peaking. Longer review will follow.
