The A7S II is certainly more of a specialist's camera than its sibling the A7R II. I think the latter is a better all-round performer and a superior buy for the more general shooter, but if you're looking for a compact system camera that offers class-leading low light performance and...

Superb video quality; Great in low light conditions; Metal-bodied toughness

It's really expensive

When Sony launched the Alpha 7 and Alpha 7R two years ago, the manufacturer was looking to target two different types of photographer. While the Alpha 7 was out to appeal to enthusiasts looking for a full-frame camera with an ‘all-round' level of performance, the Alpha 7R was aimed at landscape and...

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.

Superb video quality; Great in low light conditions; Metal-bodied toughness;

It’s really expensive;

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

At the "core" of the Sony Alpha A7S Mark II is the same full-frame 12 megapixel CMOS sensor from the A7S, which offers an extended ISO range of ISO50 up to ISO409,600 (Native ISO100 to ISO102,400).

Improved handling and design; Excellent image quality; Excellent ISO range; 4K video can be recorded internally; MicroUSB charging / power; 5-axis image stabilisation; Wi-Fi and NFC; Sony PlayMemories Apps; Dual-axis electronic level

12 megapixels may not be enough for stills photographers; Camera video fussy about memory cards; Shorter battery life than previous model; Focus struggled in low-light at times

We didn't get to review the original Sony ILCE-7S (α7S) camera, which was released in April 2014 so it's nice to receive its successor, the α7S Mark II, which was announced on 11 September 2015. The updated camera improves on its predecessor in several important ways.

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 , and at the other is the 12-megapixel Alpha 7S II ($2999.99, body only).

Full-frame 4K video recording; Incredible high ISO image quality; 5fps burst shooting; In-body image stabilization; Hinged rear display; Sharp EVF; Dust- and moisture-resistant design

Expensive; 12-megapixel resolution can be limiting; Omits PC sync socket; Overly sensitive eye sensor; No built-in flash

Really the only choice for poor/low light Video or shooting stills in the dark. Very clean at ISO 6400+ New 1080P120 is exceptionally even with internal codec. Very smooth and detailed. It can keep up with most action. Also good for slow motion that I do not use.

Most highly recommend ! You will not be disappointed!

Just about everything; I have a GH-4 I use for 4K Video and this I also use for video, but the stills are amazing; Low Light King ! Exudes quality in every aspect! Great Price

Battery Life No fully articulating touchscreen The menu system should be a little more intuitive Not many native lenses, but many more coming; Soem G Master Series just released
