I've searched the forums here and have not much found much info. I just got a Bronica ETRSi and the screen is not very bright. I would like to update the screen. My main questions are: Maxwell or Beattie? I found purchase info for Beattie, but none for Maxwell. Is Bill Maxwell still around and making screens? Will the increase in light affect my meter readings? I have the AEIII prism for my ETRSi. Thanks!
