Dpreview chose the Sony Alpha a7R II as their #1 Semi-Pro camera of 2016 over Leica, Nikon and Canon in their 2016 round up.
“The Sony α7R II wins this group for many reasons: it is arguably the most innovative, most improved, and houses the most features of any camera in this category. 399 PDAF points offer the largest frame coverage and truly challenge full-frame DSLR AF. We were in disbelief at the incredibly high AF hit rates we observed across multiple shoots, so we baselined the system against DSLRs in a slew of continuous AF tests to find that, sure enough, the α7R II challenges some of the best DSLRs, even in low light. Continuous Eye AF is a boon for candids of even moving subjects, and better-than-DSLR AF accuracy ensures critical focus for shallow depth-of-field applications. Many of these AF benefits disruptively carry over to 3rd party lenses when using electronic adapters, an industry first.
“In-body stabilization and electronic shutters allow you to worry less about handheld and mirror/shutter-induced shake, a benefit over high-resolution DSLRs. Internal 4K recording is a first for this segment, as well as BSI technology on a full-frame camera, which gives the α7R II class-leading low light image quality and continues Sony’s tradition of high dynamic range Raw imaging. The α7R II overcomes inherent issues of many DSLRs and especially the shortcomings of its predecessor, and the sum total of innovations and features help get the camera out of the way, allowing you to focus on image-making. While we still have concerns over ergonomics, and mirrorless cameras still have shortcomings for sports photography, one cannot deny the sheer photography-accelerating technical prowess of the a7R II.” –DPReview.com
