While there are plenty of digital Leica cameras out in the world, that’s not enough for some people. For example, people like robotics engineer Michael Suguitan, who has used his considerable talents to stuff a Raspberry Pi and High-Quality Camera Module into a Leica M2. It’s called the Leica MPi, and the process is completely reversible, allowing it to turn back into a standard Leica M2 at a moment’s notice.
As an MPi, it has about a 5x crop factor, which limits Michael’s lens options somewhat unless he wants to shoot super telephoto. He has been using it with a Voigtlander 12mm f/5.6 lens in order to get a field of view equivalent to about 60mm on a full-frame sensor.
