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.
