Hello,
This is a follow up to my previous 5x7 build (found here).
Again, it's a non-folding/wide-angle design to primarily fit the very beefy Super-Angulon 165 f8. It can also acomodate a 210mm lens focused to about 5 feet. I improved many things, mainly the lever driven spring back, added front-shift and front-tilt movements and (hopefully) refined the design. The bellow frames are held in place with neodymium magnets, as is the rotating back.
All wooden parts are made from Bubinga, (almost) all metal is 6061 aluminum, the black rods/tubes are carbon fiber, the ground glass is hand-ground and laser scored 1/8" acrylic, the back leaf-springs are cut from phosphor bronze and the bellows are made out of the Thorlabs BK5 fabric.
Thoughts and suggestions are very welcome.
JP
