Thanks to CameraSize we can now compare the new Sony RX1rIII size with the competition. Some claim that the Sony A7cR is a better alternative to the new RX1rIII. However, if you want the most compact full-frame camera, you can’t ignore the fact that the RX with its 35 mm lens and 2.0 aperture is much smaller than the A7cr with its lens attached:

Sony RX1rIIII vs A7cR with Zeiss 35mm f/2.8 lens (1 stop slower!) and the Sony 35mm f/1.8 (1/3 of stop faster)

The only similar E-mount lens is the Sigma 35mm f/2.0 which is quite a big longer.

The RX1rIII is just as thick with lens as the A7cR with the grip .

Now let’s compare the camera with the FujiFilm X100VI :

The Fujifilm is taller and wider but the lens si much smaller. But don’t get fooled, the Fujifilm uses a much smaller APS-C sensor and the lens is a f/3,1 equivalent in Full Frame terms. This means it has much less light gathering capability.

Here is a comparison with the Leica Q3 :

The Leica is much bigger with the only advantage of using a faster f/1.7 lens.

And here is a comparison with the Fujifilm GFX100RF :

Where the GFX100RF stands out is with the use of a compact lens (although the body itself is thicker). But also in that case they use a f/3.1 Full Frame equivalent lens only).

Wrap up:
All things considered there is no getting around that in terms of size and weight(!) the Sony RX1rIII is the smallest Full Frame camera+lens combo you can get. It is a an expensive niche camera with some “missing” features like IBIS. But there is value in a camera like this that you can easily carry with you all the time!
