Hi all
I'm interested in experimenting with faster lenses for portraiture and I'm considering the Schneider Xenar 180mm f4.5 and 210mm f4.5.
I'm happy with simply covering and uncovering the lens with a hat/cap/hand instead of a proper shutter, at least at the beginning; with a Graflex Speed Graphic being a consideration for purchase in the future.
However, I'm having difficult finding information on the mounting-thread size, in order to plan what size the screwable(threaded) hole in the lens board will need to be machined to.
If someone could provide this information, it would be greatly appreciated. (Do these old lenses have special thread spacing [threads per inch]?).
Or please merely to direct me to where information on these thread sizes.
Regards
