Is the sony rx1r good in low light?

The Sony RX1R is a full frame camera, so its sensor has a real low-light advantage. The sensor guide puts full frame at roughly one stop ahead of APS-C at the same framing and f-number, which means cleaner high-ISO files.

Its fixed 35mm f/2 lens is fast enough for dim scenes, but the camera has no stabilisation, so you'll need a faster shutter speed or a steadier grip when light drops. Full frame gives you the cleaner files, while the lack of stabilisation limits how slow you can shoot by hand.

If you want the full details, see the Sony RX1R page.
