Sony surprised the camera world by releasing the new RX1R III, as most people thought this series was gone for good. While the new camera doesn't fully meet all our expectations, we're still glad to see it return and impressed that Sony managed to keep it so compact for a full-frame model with 35mm F2 built-in lens.
In this article, we've compared its size to some of its main 'fixed-lens type' alternatives or rivals: the Leica Q3 (full-frame), Fujifilm X100VI (APS-C), and Fujifilm GFX 100RF (medium format). This is followed by a comparison of their specs and key features.
But before getting into technical details, let's look at the prices of each camera first:
