Sony Alpha 7 II
The Sony A7 II was presented just about a year after the initial Alpha 7 and differs technically little from its predecessor. Biggest changes are an integrated 5-axis image stabilizer as well as a modified case.
We generally recommend SDHC and SDXC memory cards with an UHS-I-interface and a SD Speed Class from 10/U1 or above, if you're using a Sony A7S. Expensive UHS-II-cards or just faster UHS-I-cards do not offer any advantage in terms of speed (burst mode) or video capabilities.
