PINSTAX Wide 100 modified. Initial version still needs improvements. Need to calculate adapted exposure chart, due to long exposure the film goes blue. Using warming filter solves the problem. The focal length 30mm is a bit too wide, the exposure is not even. Adding viewfinder would be nice too. Managed to get rid of all electronics and wire in such a way, that the eject mechanism cycles one time after button press.
This is proof of concept that camera can be modified. Future plans to make Mamiya press compatible version, and make a reducing back for large format camera.
Also thinking to strip the camera down even further, and make hand crank version.
