Someone here described my builds as looking 'like nightmares', and this one probably won't do anything to dispel that, but it's fun. I have a few barrel lenses for 4x5 (-ish) negative size, biased to the wide-angle, so I took a battered Speed Graphic and sawed it a couple ways to Sunday and nailed and glued it back together and got this beast. It'll focus a 6" lens to infinity but nothing longer. It fits in a big, heavy bag with 5 holders and these 3 lenses:
RED is the front element of a 38mm f/4.5 Aerogor. With both halves, this lens misses covering 6x9, but the front alone throws light all over a 4x5 frame, with a sharp center and increasing aberrations further away. Focus is about 90mm at infinity, but coverage is about equal to a 75mm-- I use the VF from a 20mm Russar 35mm lens to get ballpark composition (there's always the GG if I want to lock it down on a tripod.)
BLUE is an old Meyer Gorlitz Weitwinkel 8cm f/6.3 lens, probably from a quarter-plate folder back in the day, as it's dark at the edges but giving it the old college try. The Russar VF more or less works with this too, and I have scale focusing down to 2' 8" (and further with GG).
YELLOW (I wasn't sure this would go on this camera, but it does, and I had already used red, so...) is my Buhl 5.5" f/3.14 projection lens. Focuses down to 3' on the scale; I use my Linhof LF finder for framing but looking for a smaller option. If anybody has modified one of these for Waterhouse stops, please let me know!
