Verdictwhich should you buy?

A6600 — Hybrid Photography, Travel & Video On Sony Aps-C: The APS-C Sony that has everything — IBIS, real-time Eye AF, excellent battery life, and 4K/30p in a weather-sealed body.

A7S II — Low-Light Video, Documentary & Available-Light Filmmaking: A landmark in mirrorless history — the first Sony with IBIS and internal 4K, its low-light video capability still impresses today at a used-market price.
