Where can this lens be adapted?

The Canon EF-M mount has a flange distance of 18 mm. A plain adapter fits a camera whose flange distance is at least 1.46 mm shorter. How lens adapters work

  • Native lenses set the aperture, and often the focus, electronically. On a plain adapter they do not work. Use an electronic adapter made for this pair; for many pairs nobody makes one. Fully manual lenses are the exception.
  • Nikon ZAdapter · 2 mm

    Covers APS-C: it can vignette on a full-frame sensor.

  • Canon EF-MNative

No plain adapter reaches infinity focus on: Sony E, Canon RF, Fujifilm X, L-Mount, Micro Four Thirds, Fujifilm G (GFX), Canon EF, Nikon F.
