Shares her personal impressions from the shootings in Taganai National Park in the South Urals. She took her Canon EOS R full-frame mirrorless camera, usa 24-105mm f/4L IS USM lens and EF-EOS R adapter with her, which had to work in the harshest freezing conditions, withstanding temperatures of -25°C

Full review of the Canon EOS R mirrorless camera


I will not list the technical specifications here – this information is enough on the official Canon website, I’ll limit my personal impressions.

What I liked

– After reading the rare reviews of the new camera, I was a little scared of the many innovations I use a simple Canon EOS 6D . But it was easy to figure out the settings, everything was intuitive.

– Autofocus is incredible! Multiple focus points, easy to change. There is an exposure compensation mode that even moonlight is enough(!!! , the focus position is illuminated by the IR sensor. I was able to focus in these conditions IR sensor and moonlight from a distance of about 10 meters. This mode does not show the real picture on the screen, but much lighter – so I displayed the histogram on the screen as a reference point and forced myself not to believe my eyes.

– The lag of the electronic viewfinder is not critical, I got used to it quickly.

– at first the touch screen seemed uncomfortable, because in winter outside without gloves it’s not comfortable to shoot, but the sensitivity of the screen was reasonable and I adapted to change the settings right in my fur coats.


Shot with a Canon EOS R with EF 17-40mm f/4L USM and the following settings: 2 sec, f/22 and ISO 100.

– ISO can be adjusted from 50 to 102,000 !!! , at 6200 is quite workable, I didn’t see any ripples. I have to mention that I turn off all the noise filters in my camera I reduce noise in the editor under the control of my vision

– There’s a new Intelligent Noise Reduction function – t.e. the camera converts four very noisy frames into one not noisy one. I checked – yes, the picture is smoother, but this feature does not work with RAW and in BULB mode. Though if you shoot straight to JPG it might be useful. The camera is very easy to understand in the settings, and was very intuitive to use.k. The total shutter speed will increase.

– The big nice thing is the curtain in front of the lens lowers when you turn the camera off . During shooting, I change the lenses often and I clean the sensor after almost every trip, I even learned to do it myself. In this respect, the shutter is a very nice display of care.


Taken with a Canon EOS R with EF 17-40mm f/4L USM and the following settings: 1/180 sec, f/5.6 and ISO 200.

– There is a timer for BULB mode – with this camera it is not necessary to have a cable, you can set the necessary exposure in a few minutes directly in the camera. And if you’re shooting time-lapses or star tracks, the RS-60E3 cable connector, narrow spout.

– The adapter for EF lenses is handy native lenses work properly through it.

– The usa 24-105mm f/4L IS USM lens is designed like a trombone. For locking the moving parts while walking, there is a useful lock button.

– this lens has a third control wheel in addition to the focus wheel and manual focus for exposure compensation in automatic and semi-automatic modes – greatly speeding up adjustment, easy to use.


Taken with a Canon EOS R with EF 17-40mm f/4L USM and the following settings: &frac14 Sec, f/13 and ISO 50.

– RAW files are just rubbery! Give you the ability to correct serious exposure errors without producing artifacts in areas with smooth gradients.

– And now hardcore may Canon forgive me for my flippant treatment of the novelty the camera was exploited in -25…30°C and nothing froze, froze or slowed down! Tested in Ural winter!

Neutral torque

The electronic viewfinder and many other electronic functions require power. However, the power consumption of the EOS R is no more than that of my EOS 6D when using Live View mode. I often use the power-consuming Live View, so I considered the power-consumption point to be neutral.

On the downside

– I expected the presented mirrorless camera to be smaller and lighter than its DSLR counterparts. And in fact a set of camera EOS R + usa 24-105mm f/4L IS USM and my running set of EOS 6D + EF 17-40mm f/4L USM weighs 1.3 kg and takes the same space in the backpack.

– The old version of Adobe Camera RAW does not see the new CR3 format, so to convert RAW files, I had to take down the old pirate Photoshop and put the new version from December 2018. And in the new version of PS the developers have changed some of the functions on the shortcuts… The minus is indirect, but it will come into your life with the camera.

All in all, solid pluses and only two minuses.

My conclusion is unequivocal – I would go exploring with it!
