I recently released my second project under the name of CONFLICT.

Its a self contained rangefinder module, in the spirit of Kalarts etc. rangefinders that could be added to basically any camera.

It digitalizes the link between the camera & the rangefinder, so you can easily adapt it into wide range of cameras. And also use it on multiple cameras.

You can calibrate & store multiple lenses into it, the focal length range is 135-250mm on 4x5" film.

Though that might change, as i have not yet tested longer lenses. Not sure how small the frame lines would be.

Max close up focus distance is 55cm.

It has digital framelines that enable accurate & fully corrected framelines customized for the lens & camera combo you are using it on.

And for the film size you are using, so custom formats like 6x12 can also be easily used with accurate framelines.

Semi spot light meter and automatic bellows extension calculations etc.

It also calculates and shows graphically the depth of field in front & behind the focus point, so you can quite easily find hyperfocal etc. based on your needs.

Here is a short video clip through the viewfinder : https://www.instagram.com/p/CaGIykpjYQJ/

It uses the same tech as my AF45 project.
