Step 3 - Setup of Canon EOS M
With all the hardware put in place, you want to put your camera into the manual mode of operation or aperture priority mode (depending if you lens come with a aperture ring).
You would also need to set focus mode to manual before enabling the “Release shutter w/o lens” in the custom function of the camera.
You are now all set to begin using your Nikkor lenses on the Canon EOS M! Remember, the Canon EOS M does not offer focus peaking and hence will require a brighter screen setting to enhance your ability to confirm focus.
My personal preference would also be to flick your Canon EOS M to the multi-shot mode to improve your images’ keep rate!
