What are Sigma camera's file formats?

Please note that X3F is the high-end digital photo format exclusive to Sigma cameras. Besides, Sigma cameras also create DNG image files because DNG files can maintain high image quality. For videos, Sigma cameras usually create MOV files.

The X3F file is a RAW file saved in Sigma’s X3F format, also known as the Foveon X3 format (FOVb). This file format supports image data, thumbnails, preview images, and text properties related to captured photos.
