Sony today unveiled the new a7S II, a full-frame mirrorless camera that’s designed for amazing low light performance: its ISO range is 100-102400, expandable to 50-409600.

Inside the camera is a 12.2-megapixel full frame CMOS sensor, which is designed to optimize dynamice range while minimizing noise. Like the original a7S, which is itself a highly-regarded low-light powerhouse, the a7S II opts for less megapixels in order to have each pixel on the sensor be larger and more sensitive.

Here’s a video that shows what the camera can capture in 4K from ISO 100 up to ISO 409600:

On the back of the camera is a 3-inch, 1.23-million-dot tiltable LCD screen and an electronic viewfinder with 2.36 million dots. The XGA OLED Tru-Finder features the world’s highest viewfinder magnification of 0.78x.

Many of the still photography specs (including ISO range) are identical or similar to the original a7S, but the a7S II has a number of improvements on the video side of things, including internal 4K recording (the original a7S could only recording 4K externally).

For filmmakers, the a7S II can shoot internal 4K video in with full pixel readout without pixel binning in XAVC S. There’s also uncompressed HDMI output that lets you use an external recorder for clean 4K recording with 4:2:2 sampling. High-end movie features include S-Gamut3.Cine/S-Log3, 14-stop latitude in S-Log3 gamma, new Gamma Assist Display, enhanced Zebra Function, Full HD 120fps recording and 4x/5x slow motion recording.

Other features of the a7S II include 169 AF points (up from 25 in the original a7S), 5-axis image stabilization, a friendlier redesigned physical interface, a durable magnesium-alloy body, 5fps continuous shooting, and Wi-Fi and NFC.
