What is a MEF file?

MEF is a RAW image format used by Mamiya digital cameras, particularly in their medium-format product line. It stores unprocessed sensor data along with camera-specific metadata for high-end photography workflows.

This format preserves all the original image information, allowing for precise post-processing adjustments. MEF is designed for professional photographers who demand maximum image quality and detail.

How to open MEF files

MEF files can be opened with Mamiya’s own RAW converter software or third-party tools such as Adobe Lightroom and Photoshop. Other programs like RawTherapee and Capture One may offer partial or full support depending on the camera model.

To improve compatibility, you can convert MEF files to formats like JPG or TIFF using AnyConv.
