Canon EOS R Review

October 8, 2018 | Mark Goldstein |

Image Quality

All of the sample images in this review were taken using the 30 megapixel Fine JPEG setting, which gives an average image size of around 10Mb.

The Canon EOS R produced still images of excellent quality during the review period.

This camera produces noise-free JPEG images from ISO 50 all the way up to ISO 6400, with noise first appearing at ISO 12800. The faster settings of 25600 and 51200 display quite a lot of noise, but they're still fine to use for making smaller prints and web images. We wouldn't advise using the fastest expanded setting of ISO 102400 though.

The EOS R proved to very capable in low-light, with the maximum shutter speed of 30 seconds and the Bulb mode allowing you to capture enough light in all situations and the camera's -6EV rating successfully auto-focusing even in near-dark conditions.

The different Picture Styles and the ability to create your own are a real benefit, as are the HDR settings and multiple exposure mode, all of which can be previewed before you take the shot.


ISO sensitivity can be set between ISO 50 and ISO 102400 in full-stop increments. Here are some 100% crops which show the noise levels for each ISO setting, with JPEG on the left and RAW on the right.

Low Light

The Canon EOS R's maximum shutter speed is 30 seconds and there's a Bulb mode for even longer exposures, which is excellent news if you're seriously interested in low light photography.



The Canon EOS R's HDR Mode captures three different exposures and combines them into one, retaining more shadow and highlight detail, with an Auto mode, three different strengths and several types of HDR style available.







Multiple Exposure

The EOS R's multiple exposure mode allows you to take between two and nine images and merge them into a single photo in-camera.


Picture Styles

Canon's Picture Controls are preset combinations of different sharpness, contrast, saturation and colour tone settings. The EOS R's seven available Picture Controls are shown below in the following series, which demonstrates the differences. There are also three User Defined styes so that you can create your own look.
