Compatibility

The MC-11 is designed for full-frame Canon EF lenses. It works on any Sony E-mount body — both APS-C and full-frame. On APS-C bodies, full-frame EF lenses will be subject to the crop factor. Note that the MC-11 does not support Canon EF-S lenses, which are physically incompatible and could cause damage to the adapter or camera. Also worth knowing upfront: the adapter does not include in-adapter image stabilisation, so you'll be relying on whatever stabilisation your lens or Sony body provides.

Who is it for?

The MC-11 is a practical pick if you're switching from a Canon EF system to Sony and want to keep using your existing glass. It works especially well with Sigma's own EF-mount lenses but is also widely used with Canon EF glass. If you already own fast primes or telephoto lenses in EF mount, this second-hand adapter lets you carry them over to your Sony body without selling everything.
