At frame sizes of 1920 × 1080 and 1280 × 720, you can choose an image area using the [Image area] > [Choose image area] option in the movie shooting menu. Select [FX] to shoot movies in what is referred to as “FX-based movie format”, [DX] to shoot in “DX-based movie format”. The differences between the two are illustrated below.

  • The sizes of the areas recorded in FX- and DX-based movie formats differ. The differences are shown below.

    Format

    Area recorded

    FX-based movie format

    Approx. 35.9 × 20.2 mm

    DX-based movie format

    Approx. 23.5 × 13.2 mm

  • Movies shot with a DX-format lens and [On] selected for [Image area] > [Auto DX crop] in the movie shooting menu are recorded in DX-based movie format.

  • Image-area selection is not available at frame sizes of 3840 × 2160 and “1920 × 1080 crop”. Image area does not change when a DX lens is attached.

  • Enabling electronic vibration reduction by selecting [On] for [Electronic VR] in the movie shooting menu reduces the size of the crop, slightly increasing the apparent focal length.
