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.
  • Does not fit NP-FZ100 bodies (A7 IV, A7C II, A6700, A1, A9 III).
  • UHS-II cards fit and work in UHS-I slots but only at UHS-I speed.
