Some additional pictures of the Fujifilm GFX XΩ modular medium format mirrorless camera prototype that was presented during the recent X Summit. This specific design never reached production because the shutter mechanism was too large:
"Here are the three main modules - a grip component, the main body of the camera, and a removable EVF. The spirit of the Omega lives on in the design of the GFX 50S's viewfinder, which can be removed to make a slightly smaller, lighter camera.
The main reason why this even more modular design never saw it to production is simple - the shutter mechanism for such a large sensor was simply too large for the concept. That doesn't mean we'll never see a modular GFX, but we might have to wait for global shutters to become a practical reality first."
