  1. Dear sir
    I’m an Iranian documentary filmmaker.. I recently bought a Sony a7s iii camera, but I am in the process of choosing a memory card compatible with 4k video recording. Please introduce me the memory card and RAM reader compatible with this camera. Thank you. A.A.Valadbeigi

    1. Greetings A.A.
      In my opinion there are two good options. For the very best performance and access to all recording codecs and modes the very best cards on the market are Sony CFexpress Type A TOUGH Memory Cards with a max write speed of 700 MB/s.

      But CFexpress Type A cards aren’t cheap. So if cost is a major factor, consider Sony SF-G Tough Series UHS-II SDXC Memory Cards with a 299 MB/s max write speed which will still give you very good performance at a much lower price.

      Either way, Sony MRW-G2 CFexpress Type A/SD Memory Card Reader is my card reader of choice.
