How many lenses?
Let me preface this by saying I'm not yet using ANY of them! I get involved in simultaneously building & disassembling multiple cameras, mutating existing lenses (holding up a piece of ground glass & squinting), etc, so I never get to usig them. I decided to expend my effort and film on 6x9 folders (Moskva V & Kodak/Nagel Vollenda 620 w/ uncoated 105/4.5 Schn. Xenar) & a 35mm pinhole conversion until I learn what I'm doing before moving into LF.
-----------------------------------------
Schneider Xenar 135/4,7 in Compur (CLA'ed & attached to a 4x5 Crown Graphic)
Tominon 127/4.7 in Copal Press
Barrels
Helioprint (Agfa) 150/9 (opens up one click more than f/9...f/8 maybe?)
Helioprint (Agfa) 210/9 (opens up one click more than f/9...f/8 maybe?)
Probably use with road-kill Speed 4x5 Graphic when I build a back for it someday.
Ilex Process Paragon 376/9
Autologic Idiotar (my nomenclature; unknown origin) 6.5" f/2.3-8 very close back focus, heavy yellow filter on both sides of elements & rainbow fringing, 8" long, 4" diameter front 5" rear, removed scratched front 16" f.l. element; now has rear focus distance of about 5"! Maybe a monochromatic lens, maybe for a phototypesetter? Might continue tearing it down for large iris & barrel.
Ednalite coated triplet copy lenses, 150 mm & 170 mm f/?
Idio-gon 10" copy lens with scarlet reflection, pale green view thru lens. Likely green monochromatic for photoconductor drum in copier. Seems to be very wide field, made a frighteningly sharp telescope with a Schneider Xenon back cell - intended for my daughter in a cardboard tube, I kept it & bought her a pocket one! This will get glued onto an Ilex #3 electronic shutter/iris with hacked homebrew controller.
27" f/8-13.5 (or 16?) Opti-Copy 'Beastar', 35+ pounds, 11" long, 8" diameter. Monochromatic but 'color corrected, one at a time', (hunh?) color separation lens for 40x60 'blowbacks' onto 15"x21" film for book publishing. Used with green filtered pulsed Xenon light source and sometimes yellow filter on lens. Certified horrendously non-APO (up to 1" focus shift for different color light) upon attempting to use as an LF lens, might cover 8x10 @ infinity. Plan is to use with 420 nm marine fluorescent lamps as cold head enlarger (11x14 maybe?) & graded paper.
Box o' Rodenstock-Ysarex 127/4.5 (Polaroid 110B? ) front cells (various condition, neg. cell, roughly -4.7 diopter (-24.7 + 20), from my crude experiments
Other
