The Canon EF-M is a strictly manual focus camera that uses the Canon EF (auto focus) lenses. It is the only manual focus camera in the whole EF lens lineup. Want to use modern EF lenses but have no interest in letting the camera do any of the focus work? This is the camera for you. Otherwise, the EF-M works very similarly to the Canon EOS 1000. It is capable of full manual exposure or full program, with aperture and shutter priority in between. The split prism focusing screen is often sought after for installation in other Canon EOS cameras. It has a few other features, such as exposure compensation, but the EF-M is a simple, stripped-down body meant to be sold inexpensively for the export market.

Canon EF-M
Here's a rare bird for you: the Canon EF-M. It is the only camera in the Canon EF lens mount family that is not auto-focus. That's right, manual focus only with that collection of EF lenses you've got lying around. Why? Well, we're not quite sure and it seems many other photographers were also confusing by this, as the camera didn't last on the market for too long. ⠀
A couple of other odd points to add about this camera is that, while it does have a bulb mode, it does not have a cable release socket. The camera uses manual dials for shutter and aperture control. One last fact, the Canon EF has a split prism focusing screen that Canon users love to remove and install in their auto focus EOS cameras.
