Sony Alpha 7S Review

 

The a7S is the third model in Sony's full-frame mirrorless lineup, a 12MP camera that puts as much emphasis on its movie capture capabilities as its still image prowess. While the a7S is a capable still shooter, Sony has emphasized that its real focus...

Impressive image quality Superb, detailed, essentially moiré-free 1080p footage Outstanding 4K (UHD) video when used with external recorder Useful, high resolution electronic viewfinder Completely silent shooting available Microphone and headphone...

Limited to contrast-detect AF, while a7/II siblings have on-sensor phase-detect AF Lower dynamic range and resolution than immediate competitors Sony's Raw compression scheme can lead to posterization at high contrast edges Small battery can be...

The Sony a7S is an interesting departure for a camera company: a model where possibly more of the emphasis during the design process has been placed on video capture, rather than stills. This is made easier to see by the existence of its sibling...

Sony Alpha 7S

 

The Sony Alpha 7S full-frame mirrorless camera offers incredible performance in low light, but you'll need an external recorder to take advantage of its 4K video support.

Amazing high ISO capability. Full-frame image sensor. 5fps burst shooting. Sharp, tilting rear LCD. Excellent OLED EVF. Great control layout. Compact, dust and moisture-resistant body. Vertical shooting grip available.

4K recording requires external recorder. No PC sync socket. No built-in flash. Limited native lens selection. Overactive EVF eye sensor.

The EVF is an OLED panel with a 2,359k-dot resolution, similar to the one found in the APS-C Alpha NEX-7. It's one of the best you'll find in a digital camera, although we give slight preference to the LCD EVF in the Olympus OM-D E-M1. The LCD tends to...

Sony α7S

 

Joining a growing family of full-frame image sensor cameras -- including the α99, VG900, RX1, α7 and α7R -- Sony has announced the α7S, or Alpha 7S. Along with its two Alpha 7 siblings, the α7S is the world's smallest full-frame interchangeable lens...

Sony Alpha a7S Compact 4k Camera Review

 

Last year, Sony really tried to do something different when they unveiled the first true full-frame mirrorless cameras. The A7S is a follow-up to the A7 and the A7R, a series that began with a simple principle: put a heavy pro-grade DSLR into something...

Good for 4K ; Extremely good ISO range at 100-409,600 ; Large grip ; Very good in low-light situations ; Silent and digital shutter

No way to see 4K footage well, just yet ; Menu button location ; AF misfunctions on moving subjects ; Drains battery very fast

If you are looking for a DSLR with a light weight, the A7S is your camera. It is full of a lot of features that are not on most DSLRs, and if not for that 4K external issue, it would be ideal.

Sony A7S Review

 

The Sony A7S is a 35mm full-frame compact system camera with a 12.2 megapixel sensor that provides an incredible ISO range of 50-409,600 and high dynamic range. Other standout highlights of the A7S include 4K movie recording (24p and 25p), XAVC S Full...

If low-light shooting is your thing, then the Sony A7S should be right at the top of your shopping list. Offering a killer combination of massive ISO range, 15-stop dynamic range, sensible 12 megapixel resolution on a full-frame sensor, truly silent...

Sony A7S Review

 

With a unique 12-megapixel 35mm sensor, the Sony A7S able to shoot in very low light with impressive high ISO performance up to ISO 409,600! The sensor is tailor-made for 4K video for excellent detail, plus very wide dynamic range. XAVC S high bitrate...

Outstanding high ISO performance; excellent dynamic range; 4K video recording (via uncompressed HDMI); XAVC S option for HD video; Slightly improved battery life over A7/A7R; Built-in Wi-Fi & NFC connectivity

4K video requires expensive external recorder; Sluggish startup time; Loud shutter; Silent Shooting mode hurts image quality; Lacks a built-in, pop-up flash; Limited selection of native Sony FE lenses

Sony A7S II Review

 

The Sony A7S II takes the A7S to the next level. The redesigned camera body, improved autofocus, and bevy of new features make the A7S II a very capable full-frame mirrorless camera no matter the lighting conditions.

Comfortable and surprisingly compact camera body; Improved low light performance; Built-in image stabilization; Wide range of usable ISOs; More sophisticated autofocus performance; Excellent video capabilities.

Relatively low resolution; Mediocre continuous shooting performance; No built-in flash; No losslessly compressed RAW option.

Sony A7s Review: The New King of Full-Frame Video

 

Sony's moves in the field of consumer electronics can seem genius at times, and baffling at others. Its new full-frame mirrorless camera, the A7s, is a little bit of both. It's a camera that looks and functions exactly as previous A7 models, but with a...
