    Looking good! It will be really interesting to see a portrait, when you have it complete.

    A DIY 177mm f/8 Cooke triplet for 4x5 from off-the shelf lenses that YOU can build

    Thanks.

    Flange focal length (distance from the outside mounting flange to image plane) measures ~ 165mm. Reversed, focal length measures 200. Very rough measurements of course. Maybe I'll have a 2-step zoom

    Next I'll either pull the optics to machine the slot for the waterhouse stops, or make a lensboard to mount it to my camera. Slow and steady, or go for broke? Decisions, decisions...
