Canon Joins the Full-Frame Mirrorless Game: Announces the EOS R

  By Kaitlyn Kerr


Canon has announced their entry into the full-frame mirrorless world: the brand new Canon EOS R.

The latest EOS mirrorless camera features a brand new full frame sensor with 30.3MP, a DIGIC 8 processor, and a Dual-Pixel AF system with 5655 selectable autofocus points.

The camera features a fully articulating LCD (same as the 6D Mark II), an EVF with 3.69 million dots and a brand new “Fv” exposure mode. Canon has also done away with their typical aperture dial to help keep the body small, instead choosing to build a custom ring into all their new RF lenses and one of their new adapters that can be used to control aperture. They have also implemented a new touch-bar, which can be customized to change ISO, white balance and more. Current Canon shooters will also be pleased that the camera uses the same LP-E6N battery as much of the EOS lineup. A grip (BG-E22) that takes two batteries will also be available.

The EOS R will be fully compatible with both EF and EF-S mount lenses. The mount’s design has the same 54mm inner diameter, but a shorter flange distance, allowing RF lens designs to have fewer elements and better control over aberrations and extremity performance, in addition to making the body smaller.

Four lenses will also launch with the camera, including a 24-105mm f4 IS (smaller than the same focal length EF lens), a 35mm f1.8 IS Macro, a 50mm f1.2, and a 28-70mm f2. Both stabilized lenses are rated for 5 stops of stabilization.

There will be three different mount adapters available as well. The most basic will allow use of EF, EF-S, TS-E and MP-E lenses. Another also has a customizable control ring (similarly to the RF lenses, that can be used to control aperture), and the third will allow you to drop filters in between the lens and the body, allowing you to own a single set of filters (polarizers and NDs) and use them with all lenses without the worry of filter thread sizes. This filter adapter will be available with a choice of a polarizer or variable ND filter.

The video specs indicate that the camera can record 4K/30p with an output of 4:2:2 10-bit via HDMI, and supports C-log right from the box. An integrated headphone and mic jack will also be welcome for video users. The camera still has a pretty heavy crop in 4K mode (1.67), but uses a more manageable MPEG codec (compared to the MJPEG codec used in the 5D IV).

Other specs:

– Native ISO range is 100-40,000, expandable to 50-102,400
– 8fps in AF-S, 5fps in AF-C (which drops to 3fps if put in tracking priority)
– 1/8000 max shutter speed
– Built-in time lapse mode
– 5655 selectable autofocus points with 88% vertical coverage and 100% horizontal coverage
– Single UHS-II SD slot
