Menu item details

Records images in uncompressed RAW format. When [Uncompressed] is selected for [RAW File Type], the file size of the image will be larger than if it were recorded in lossless compressed RAW format or compressed RAW format.

Lossless Comp (L)/Lossless Comp (M)/Lossless Comp (S) *:
Records images with a lossless compression method that causes no deterioration** in image quality and has a high compression rate. The file size is smaller than when [Uncompressed] is selected.
  • You can select L/M/S as the image size. The number of pixels after development using a Sony application is the same as the L/M/S size for JPEG/HEIF images.
  • The L size can be selected only when shooting in full frame. When shooting in the M or S size, the pixel number does not change for full-frame shooting or APS-C-size shooting.

*When the camera’s system software (firmware) version is Ver.1.10 or later

**The M size and S size reduce the image size, so the image resolution will be lower than that of the L size.

Records images in compressed RAW format. The file size of the image will be approximately half of that with [Uncompressed].


  • The [RAW File Type] icons are displayed as shown below.
    • Uncompressed:

    • Compressed:
  • When shooting in the lossless compressed RAW format, the aspect ratio for RAW images is always 3:2. JPEG/HEIF images are recorded with the aspect ratio set in [Aspect Ratio] when RAW images and JPEG/HEIF images are recorded at the same time.


  • You cannot record RAW images with different formats to Slot 1 and Slot 2. Even when [Recording Media] is set to [Sort Recording], each slot has the same setting for [RAW File Type].
