Canon EOS M RAW Files: Open, Cull & Edit .CR2 Free

Canon's first mirrorless camera, bought mainly as a compact travel companion by existing EOS DSLR owners. Autofocus speed was modest at launch, which meant many users shot multiple attempts per subject to guarantee a sharp frame. That habit makes duplicate detection a natural fit for cleaning up early EOS M archives.

Editing EOS M files with imagic

imagic opens .CR2 files from the Canon EOS M natively on Windows and macOS. Point it at a card or shoot folder and it builds previews, scores every frame for sharpness, closed eyes, and composition, and groups near-duplicate bursts — so a full shoot collapses to its keepers before you edit anything.

Processing runs through the bundled RawTherapee engine, entirely on your machine: batch-apply one look across the keepers and export JPEGs in a single pass. Nothing uploads, which matters at about 18-22 MB per frame. The 7-day trial is full-featured and needs no card; licenses are one-time, from €19.
