Ahh, the Technika Press aka Press 23 -
Pretty sure it was standard filter threads
My dad swore by the lenses on Linhof MF cameras, but hated the cameras (Linhof had select pick of Zeiss lenses) - the Press 70 is heavy and unreliable http://www.arnecroell.com/zeissoberkochen.pdf Cool article about Zeiss MF and LF lenses
Just getting familiar with the thing and doing some tuneups. The dark slide was rusty in places, the viewfinder was cloudy, thought the film advance release slider was kaput (it's not), loosened up the stiff focusing helix, and loaded a roll of film. This thing is over the top in build strength, size, and weight. The mother of all beasts.
I'll trade some weight for build strength. There's more than a little satisfaction w/ quality & precision. I don't have experience w/ resurrecting cameras, but I love it when a noble old war horse gets some love & continues to amaze with performance. 'Can't wait to see stuff from it.
