Canon EOS R vs R6
The EOS R was launched in 2018 and inaugurated Canon’s full frame RF system.
Two years later we got the EOS R6 with more promising specifications. How do they compare?
The two cameras are similar in size and weight. The R6 has a few extra buttons (including an AF Joystick). The EOS R has a small LCD on top and a touch bar on the rear.
The EOS R has a single SD card slot (UHS-II) whereas the EOS R6 has two UHS-II SD slots.
Viewfinder and LCD
They have the same viewfinder, except for the faster refresh rate on the R6 (120Hz). The touch LCD screen is slightly larger and has more resolution on the R6.
The EOS R has an older full frame sensor with 30.3MP whereas the R6 has 20.1MP. The R6 has a vaster ISO range topping out at 204,800 ISO. The EOS R stops at 102,400 ISO.
With the R6 you can take HDR photos (HEIF format) using the HDR PQ gamma curve, which delivers more tonal range than the standard JPG file.
Both cameras use Canon's Dual Pixel CMOS AF. The R6 has a new version that includes deep learning technology and can track the body, face and eyes of animals.
The EOS R can shoot at 8fps with Single AF, or 5fps with C-AF (3fps if you want focus priority). The R6 can do 12fps (mechanical shutter) or 20fps (electronic shutter).
Unlike the EOS R, the R6 features 5-axis IBIS with a maximum compensation rating of 8 stops (CIPA) when paired with select lenses.
The EOS R can record 4K up to 30p but with a heavy 1.7x sensor crop. The R6 has a minor crop (1.07x), and goes up to 60p with 10-bit internal recording.
The Canon EOS R can be found for $1800, £1880 or €2000. The R6 starts at $2500, or £2500 / €2800. (Prices as of January 2021)
The R6 has many characteristics that make it superior to the EOS R, and more competitive against the likes of Sony and Nikon.
