i am finally getting around to building a working prototype with the cine lens. i have taken the flash, capacitor and battery box off the front of the circuit board. this is because the lens need to get quite close to the sensor and moving the whole board forward is easier than relocating the sensor.

this frame will hold the lens in relation to the circuit board. i will then encase the whole thing in a vac-formed plastic shell. the threads on the lens mount dont go right up to the flange and so dont grip the thin metal. on the left you can see two plastic nuts to thread on from behind.

as you can see i went for the thinner, red nut. i just drilled the hole slightly too small and  worked it on slowly.

the lens held securely in place.


here you can see the electronics hels in the frame. the screws are in slots rather than holes so i can adjust the flange distance to get it just right. i intend to place the camera a measured distance from an object and set the lens to that distance. then i will move the sensor in relation to the lens until the object is perfectly focused.

another view. you can see that the lens is miles over to the left and quite high. that is the down side of using donor cameras. but building from scratch just wont happen in my timeframe.
