The advent of the high-quality version of the Raspberry Pi camera has given experimenters a good-enough quality camera system that they can use it to create better devices than mere snapshot cameras. It’s been used by experimenters for some exciting projects, but so far, very few of them have broken away from the Pi camera’s C-mount lens system. [Tom Schucker]’s Pieca is an interesting departure then, because it takes the Pi HQ camera into new territory by using Leica rangefinder lenses.
There are enough Pi camera projects that by now the process of setting one up should be pretty well known. This one is a bit different in its use of a focal length reducer, mounted inside a 3D-printed Leica lens mounting plate. The result is that the Leica lens is better matched to the much smaller size of the Pi camera sensor compared to a 35mm frame.
The camera’s aesthetic design is on the chunky side, probably because of the choice of a Pi 4 rather than a Pi Zero. It remains very usable though, and produces photographs with a distinctive feel. You can see more in the video below the break. Meanwhile if you aren’t lucky enough to own a stable of Leica lenses, perhaps you could think about adapting more common optics? We’ve seen it before with the original Pi camera.
