Mention Canon and 4K in the same sentence and you're likely to upset some videographer in your vicinity. That may be about to change, however, as it looks like Canon will be bringing 4K to their next mirrorless camera.
The good people over at Canon Rumors are reporting that Canon's upcoming mirrorless camera (likely being announced this month), the EOS M50, will have 4K video capabilities. While specifications beyond that are not known, it's an important step forward for Canon's mirrorless line. The camera will use the EF-M mount, but that mount can accept EF and EF-S glass with an adapter. How well Canon's lauded DPAF will perform with an adapter and the new camera remains to be seen, but with some good manual focus aids, it could be an excellent, small 4K option for filmmakers. Canon's EOS M5 was the first indication that the company is taking mirrorless seriously, and reviews have indicated good autofocus performance with adapted EF lenses. Canon's advantage over the far more advanced mirrorless options from Fuji and Sony is their extensive lens library, and if they can start creating bodies to match, they'll retain their lead. 2018 will be a very interesting year for the mirrorless market.
