Greetings from the Editorial team. This is the review article for the Canon EOS R, full frame mirrorless camera which was launched recently. Review by our guest author Ravi Dhingra.


The wait is finally over, as expected Canon has come up with a full frame mirrorless camera. Canon introduced crop sensor mirrorless cameras around four years back but did not aggressively promote these till EOS M50 was launched sometime back. With the competition increasing in full frame mirrorless category cameras, Canon has come up with EOS R system – Reimagining future. It is almost after 30 years after the introduction of EOS and EF mount, a major change is being brought in with the new R mount.

Canon EOS R Specifications

Continuing with the philosophy of selling cameras which provide excellent image quality, ease of use and durability, the magnesium alloy body with the patented grip and placement of buttons makes this camera not only durable, easy to handle but good looking too. The diameter of mount remains the same at 54 mm. But the distance between the mount and sensor plane has come down to 20 mm. In fact, in future it will help in designing better quality compact lenses with the wider aperture like f 1.0

The programmable ring on lens to control exposure and touch bar with multi-functions on the body are the new, unique and innovative features offered, both of these will make clicking photographs faster with more ease.

Powerful image stabilization (IS) effect of up to 5 stops

The algorithm to detect camera shake is an evolution from that of EOS DSLR cameras. This IS system acquires camera shake data from both a gyroscopic sensor in the lens and image data from the camera’s CMOS sensor. The Dual Sensing IS system can accurately detect and compensate for low frequency (slow) blur. Earlier, it used to be hard to detect with gyroscopic sensors alone. As a result, the camera-shake blur is reduced by the equivalent of a 5-stop faster shutter speed.


Combination of optical and electronic IS systems greatly reduce blur caused by low-frequency camera shake. When a compatible lens is attached, the camera’s combination IS system uses both the Electronic IS for movies (in the camera) and optical IS in the lens. Hence, it significantly improve the performance of 5 axis camera-shake blur compensation.

Right now four R mount lenses have been announced but with the adapter. Therefore, all EF and EFS lenses can be used. The battery of Canon EOS R remains the same as in 5D & 6 D series, LP-E6/LP-E6N. All these features are added advantage for photographers who are already using Canon DSLRs. Also, for new users who are planning to buy one and want to buy the R mount camera as their first body or an extra body.
