      Photography Features

      Cameras are equipped with BIONZ processor.


      Lens Mount

      Cameras have Sony A lens mount. Due to their APS-C sensor their crop factor (also called lens multiplier) is equal to 1.5x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.


      In-Body Image Stabilization

      The cameras have a built-in Sensor Shift in-body image stabilization (IBIS). This means that you are still getting vibration reduction when cameras are paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.

      Connectivity, Battery and Storage

      USB Inputs and HDMI Outputs

      Both models have USB 2.0 (480 Mbit/sec) inputs for data transfer. Both cameras have HDMI connector for video signal output.
