Justin Dise put the new Sony A7R II through its paces for B&H Photo. "Ever since it was first announced," Dise writes, "the a7RII is a camera that I couldn't wait to get my hands on, as it is the first in the a7 family to record 4K (UHD) video internally; a feature that many a7S owners—myself included—would love to have. The camera seemed almost too good to be true, offering internal 4K (3840 x 2160) recording in full-frame and Super 35 modes, S-Log2 gamma, 5-axis in-camera stabilization, and the promise of good low-light performance despite its 42MP sensor.
"While on paper, the a7RII has most of the boxes checked off with the features I’m looking for in a compact cinema camera," he continues, "I was eager to see how it performed out in the real world, to see if it truly lives up to the hype. In my opinion, it absolutely does. But alas, no camera is perfect, and neither is a7RII. It is not without it quirks and caveats, including the familiar foe that the a7S and DSLR/mirrorless shooters oft fight against: rolling shutter."
Dise goes on to enumerate the pros and cons as he saw them in the piece and to demonstrate, he posted this video.
