Model scope, caveats and source dates

Sony α7 IV (ILCE-7M4) only. Do not substitute a similarly named reader, later revision or regional bundle.

  • Recording format, bitrate, card speed class, firmware and exact-card suitability remain separate checks.
  • Selecting Slot 1 does not reserve or configure it; the worksheet does not read or change the camera.

No automatic USB handoff. Camera direct transfer, USB4 negotiation and alternate or captive upstream topology require a separate documented workflow.
