The Konost FF is a full frame digital rangefinder camera that is currently seeking funding opportunities. The prototype shown has an optical viewfinder with electronic frame-lines and a focusing patch:
With a 20.0 megapixel 35mm full-frame image sensor, the Konost camera delivers image quality on par with any modern camera. Our analogy is to think of it as driving a 800hp manual Ferrari.
There are only a handful of digital rangefinder cameras on the market today, a domination held by Leica Cameras. The Konost camera is unique in that instead of using rotating mirrors and prisms in the rangefinder mechanism, it uses a secondary image sensor and image processing algorithms to display the rangefinder patch in the viewfinder. This allows the camera to be all-digital, decreasing manufacturing costs, and does not require high maintenance or re-callibration.
