Скачать или смотреть Sony A7s II vs A7r II review : 4k noise compared

Review: http://www.cameralabs.com/reviews/Son...

My second comparison compares 4k noise levels between the Sony A7s Mark II and the A7r Mark II. Again I filmed a scene with the three 4k UHD modes: A7s Mark II with its full-frame coverage, the A7r Mark II in its APSC crop and the A7r Mark II again with its full-frame option.

This time all the clips were filmed in 24p at sensitivities starting at 1600 ISO and going up to the maximum values: 25600 ISO on the A7r Mark II and 409600 ISO on the A7s Mark II. Once again I've presented the unscaled footage from all three on a 4k frame by cropping them, although this time horizontally; the vertical height is untouched. As before I used the FE 16-35mm lens (closed to f5.6 here), and adjusted the zoom on the APSC footage to match the field-of-view of the full-frame versions. Picture Profiles were off here - this is footage straight out-of-camera, although I have also posted samples on my review you can download with PP8 for grading tests.
