Years ago I did publish a couple of patents about a modular Olympus camera (Click here to read the patent that shows 8 different modular bodies). Of course this is now a dead project. A source shared some insights on this “experiment”:

• Unlike the Ricoh GXR solution were sensor and lens were part of one single unit Olympus developed a fully modular system were every single part can be replaced.
• The very cool thing is that you could rotate the sensor, and also use different sized sensors (!).
• LCD and EVF were detachable (you can control the camera via wireless using the detached LCD).
• It was meant as an open concept, it means third party companies could make single parts for the system. The Olympus prototype camera for example used both Kodak and Panasonic sensors.
• The main body of the camera was mirrorless but you can attach a special adapter with included mirror to be able to use Optical View Finder.
• It was a very advanced camera and that is probably also the problem of the whole project. To make it work flawlessly you have to work on many details. I have been told that engineers were facing many problems.

Old times folks, now Olympus is gone and we have to see if JIP will have the guts to try something new…
