Sony Alpha 7S II
The Sony A7s II is again primarily aimed at filmmakers, who can enjoy a full-frame sensor with "only" 12 megapixels resolution, which ensures extremely low noise at high ISO. In comparison to its predecessor, an integrated 4K recording is now also available.
We generally recommend SDXC memory cards (64GB and more) with an UHS-I-interface and a SD Speed Class from U3/V30 or above, if you're using a Sony Alpha 7S II. Extremely expensive UHS-II-cards or just faster UHS-I-cards do not offer any advantage in terms of speed (burst shooting) or video capabilities.
