Overall, despite its very high price, we love the Sony A7S II and for users who want a superb compact mirrorless camera for low light video and photo shooting, we pretty much can't recommend a better device.

Absolutely superb nigh and low light shooting ability; Excellent EXMOR full-frame sensor; Robust build; 169 AF points; Massive ISO; Remarkably crisp 4K and Full HD video quality

Expensive; very expensive; Could use better organized touchscreen menu controls

So far, we're expecting pretty much more of the same–excellent high ISO results, great focusing, but not incredibly detailed images since this is just a 12.2MP sensor. But that's what the A7 Mk II and the A7r Mk II are for.

Read various reviews of whining on small buttons and difficult menus, but I myself think that the menus, you learn that at any other camera at any time, and the buttons feel solid and distinct. Coming from Canon or Nikon, you learn about, nothing more to it.

I have used the A7SII for over a year and stunning says it all. From stills to video, especially in low light, the system performs as advertised. Have shot in all conditions with no complications save that the sensor is a dust magnet and must be cleaned from time to time.

Bringing its line of full-frame interchangeable-lens mirrorless cameras up to six models, Sony launches the last of the Mark II updates: the A7S II. The upgrades to the video-focused A7S II mostly bring the design and features introduced with the A7R II , but they're pretty important -- some might say essential -- changes for this model's intended user. At its core, however, the A7S II retains the same large 12.2-megapixel, high-sensitivity sensor.

Sony's full-frame Mark II hat trick concludes with an update to its low-light and video-optimized mirrorless model.

Sony continues to take a three-camera approach with its second-generation full-frame mirrorless system. At one end of the spectrum sits the high-resolution, 42-megapixel Alpha 7R II ($1,198.00 at Amazon) , and at the other is the 12-megapixel Alpha 7S II ($2999.99, body only). The low pixel count goes a long way to improve image quality at extremely high ISOs—the camera can be set as high as ISO 409600—and also improves the quality of 4K video. Our Editors' Choice for full-frame mirrorless cameras is still the Alpha 7 II ($1,198.00 at Amazon) . This third musketeer in the group features a 24-megapixel image sensor, a low price, and solid all-around performance, but it doesn't support 4K video capture. DesignThe Alpha 7S II shares the same physical design, interface, and controls as its two twin siblings. For information on how the camera handles, you can refer to our review of the Alpha 7R II.
