That was freakishly bright, I forget what screen it had, but it had the LED's.? F2S I think, not the F2AS.? It was really bright. ________________________________ From: Marty Deveney <benedenia at gmail.com> To: Leica Users Group <lug at leica-users.org> Sent: Saturday, July 14, 2012 8:02 PM Subject: Re: [Leica] Was WTB: Nikon AR-1 soft release now finders Sure, I was only commenting on using modern AF SLRs for manual focus work, not on your observations, which are entirely valid. Your F2/3 cameras are ~30-40+ year old technology and screens do deteriorate with time.
