Canon’s cinema lineup has so far been dominated by EF-mount offerings. The only cinema cameras in the list with the mirrorless RF mount are the EOS C70 and the EOS R5 C since the C300 and the like still stick with EF.
Glass has up to this point has been exclusively using their SLR mount—until today. Canon has just revealed new full-frame CN-R series of cinema primes that builds upon the classic lens lineup with a native RF mount.
The good folks at B&H Photo Video have gotten an early preview of the new RF-mount cinema glass and put together a nice, quick overview that is worth checking out.
There are going to be seven lenses in the RF lineup:
You’ll notice this closely matches the existing EF-mount lineup. All the lenses are relatively fast for their focal lengths and have matched locations for iris and focus gearing as you would expect from a series like this.
Getting into the new details, you’ll probably figure out that the biggest difference is simply the native RF mount on the new lenses.
The lenses are still of very high quality with the ability to resolve up to 8K resolution on modern full-frame systems. This is helpful since cameras like the R5 C are likely to be used with this glass.

That RF mount is a bit more special than the EF mount. Thanks to increased bandwidth on the connection, these lenses can “talk” to the cameras with more data and take advantage of newer features.
This includes in-camera distortion correction as well as existing features like aberration correction.
Consistency is key and they are designed to match the EF versions closely. They have the same length, except for the 14mm and 135mm due to their designs.
The filter thread is matched at 105mm, except for the 14mm which has no filter thread.

All the lenses have markings that can be viewed on either side of the lens for easier operation and all the markings are phosphorescent so they can be seen in the dark.
It’s nice to see Canon bringing native glass to the RF mount. It does mean that Canon now offers lenses for RF, EF, and PL mounts.
What do you think about these new lenses? Worth picking up over the EF-mount versions?
