Mamiya RAW (MEF) is a raw camera image format (or family of formats?) used by some Mamiya digital cameras.

Format

At least some MEF files use DNG format, or something similar to DNG. The first IFD (refer to TIFF) contains a thumbnail image, and is expected to have three sub-IFDs. The first sub-IFD contains the full-resolution image, and the others contain reduced-resolution images.

There is also an Exif IFD. It includes a MakerNote with no signature, which appears to be an integrated or embedded IFD.
