Good to know
  • APS-C "E" lenses (e.g. E 18-135mm, SEL18135) mount on full-frame bodies but the camera records an APS-C crop, so you lose resolution and field of view.
  • FE (full-frame) lenses work on APS-C bodies with a ~1.5x narrower field of view.
  • Third-party lenses (Sigma, Tamron) are sold in separate mount versions; buy the Sony E-mount version.
  • Not interchangeable with the smaller NP-FW50: the A6400 and ZV-E10 use NP-FW50 while the A6700 uses NP-FZ100.
  • UHS-I cards work in UHS-II slots at UHS-I speed; high-bitrate video modes may need a V60/V90 UHS-II card.
  • Not interchangeable with CFexpress Type B (different size).
