Canon EOS R6 Review

August 4, 2020 | Mark Goldstein |

Image Quality

All of the sample images in this review were taken using the 20.1 megapixel Fine JPEG setting, which gives an average image size of around 7Mb.

The Canon EOS R6 produced still images of outstanding quality during the review period.

Thanks to its modest 20 megapixel sensor, this camera produces noise-free JPEG images from ISO 50 all the way up to ISO 12800, with noise first appearing at ISO 25600. The faster settings of 51200 and 102400 display quite a lot of noise, but they're still fine to use for making smaller prints and web images. Even the fastest expanded setting of ISO 204800 can be used at a push.

The EOS R6 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 -6.5EV 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. Support for the new HEIF 10-bit file format is a little thin on the ground, but should offer a degree of future-proofing.

Noise

ISO sensitivity can be set between ISO 50 and ISO 204800 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.

File Quality

The Canon EOS R6 has three different file quality settings - Raw, Fine and Normal. Here are some 100% crops which show the difference.

Fine (13.7Mb) (100% Crop) Normal (8.37Mb) (100% Crop)

JPEG vs HEIF

Compared with the 8 bits (256-level greyscale) of the JPEG format, HEIF is capable of storing image data at 10 bits (1024-level greyscale) or higher, and also supports the Rec. 2020 standard, which boasts an extremely wide color gamut.

What’s more, HEIF is compatible with the HEVC (H.265) codec, which offers a higher compression efficiency in storage compared with JPEG files of the same image quality.

HEIF

Night

The Canon EOS R6'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.

HDR

The Canon EOS R6'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 R6'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 R6'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.
