The Sony a7S is an amazing camera for a few, but it’s not the right camera for most people. The sensor separates the A7S from every other camera on the market. It’s full-frame, but only 12 megapixels. That means that each of the 12,000,000 pixels is much larger than other full-frame cameras, and thus gathers much more light. Sony designed a 12-megapixel sensor to optimize it for recording HD and 4k video. As a result of that optimization and the large pixels, it’s simply amazing for low-light video. If that’s what you need, this is the camera for you. If you want low-light stills, just about any other full-frame camera can give you similar results once you scale the images down to 12 megapixels. Another benefit of the a7S is that it has an electronic shutter that allows for completely silent shooting; if you must be silent and work in low light, this is an ideal camera. The Panasonic GH4 also has a silent shutter option; however, the smaller Micro Four-Thirds sensor produces much more noise.

  • Unbeatable low-light 4k video
  • Video has a fantastic dynamic range


  • Generally a terrible stills camera with only 12 megapixels
  • Low-light images are not any cleaner than a D810 or a7 II, and less sharp
  • Requires an external recorder for 4k video
  • Autofocus capabilities are shameful
  • Lacks a touch screen
  • A fully articulating screen would be more useful for video
  • Sony’s native lens selection is more limited than Canon and Nikon
