Fuji-X focusable 3D stereo lens

thingiverse

Required: 2x 40mm achromats - I used these here: https://www.surplusshed.com/pages/item/L2010.html What: This is an early attempt at a stereo camera lens that I can use with my Fujifilm XE-3. It re-uses a previous design I had for the body mount (see here: https://www.thingiverse.com/thing:4981367) and resurrects one of my old focusing ring designs. The lens chassis has several pins which fit into grooves coming perpendicular out of the lens body; these pins then slot into spiral grooves in the focusing ring. Turning the focusing ring moves the chassis forward without rotating it; any rotations would break the stereo. I've added some baffles at the back of the lens to crop the stereo image so the left/right pairs don't interfere with each other (loosely derived from a great design from geo.moua over on IG). Note that the baffles drop into the camera body itself so BE CAREFUL! It worked for me on my XE-3 without colliding with anything, but your mileage may vary. The stereo baseline on this is teeny tiny (17mm); I have a plan for trying this again but with mirrors to get a decent stereo separation. Printing: As detailed as you can get it; I used a 0.1mm layer height and it worked out great.
