Panasonic Lumix DC-S1R review at Dpreview:

Dpreview published the full Panasonic S1R review:

The Panasonic Lumix DC-S1R is an impressively well-built full-frame mirrorless camera with lots of resolution, well thought-out controls and ergonomics and competitive video quality. Unfortunately its burst shooting speeds are simply outdone by the competition and for less money, and it falls slightly behind in overall image quality and autofocus performance as well. But the fact remains that the S1R is enjoyable to use and is worth a look for those that want a well-rounded high-resolution professional camera.
