Review Excerpt

Superb image quality at low, moderate ISOs; Improved high ISO performance; Fast continuous shooting speeds; Very impressive hybrid autofocus; High-quality 4K UHD video; Rugged camera body.
Multi-selector joystick can be awkward to use; No EVF live view at fastest burst rate; Buffer clearing is slow with no UHS-II support; 4K UHD video isn't as full-featured as E-mount counterparts.
Read our Sony A99 II Review

20MP sensor; Better per-pixel sharpness; Very good, slightly improved dynamic range and high ISOs; Stellar 4K video up to 60p with no crop; 6K Photo; Dual UHS-II SD slots; Good battery life for its class.
Buffer is deep, but slow to clear; Expensive; Menus still confusing; No optical low-pass filter means greater risk of moire; No built-in flash.
