Canon EOS R5 Performance

The performance section is where we look at the image quality performance of the camera. Additional sample photos and product shots are available in the Equipment Database, where you can add your own review, photos and product ratings.

 

Canon EOS R5 Sample Photos

Sample Photos - The camera gives Canon's signature colour reproduction, with quite neutral colour reproduction. For more punch, you can under-expose and adjust the picture style used. Images can look a little over-exposed at times, however, this is fairly typical behaviour for Canon cameras, and can easily be adjusted to your own personal tastes. Face and eye-detection autofocus work well, and AF performance was generally good, although could miss moving rapidly people at times. AF tracking was impressive, and there are multiple options to customise how the camera responds to moving subjects. Animal recognition works, to detect dogs, cats, and birds.

Lens correction is built-in to the camera. The 24-70mm f/2.8 lens performs well, with sharp detailed images. We didn't spot any issues with vignetting, purple fringing, or chromatic aberrations. We didn't spot any lens flare. The lens gives reasonable close-up performance, able to focus on small subjects, such as bees and other small insects.

The camera supports HEIF files, which aren't currently supported by Adobe Photoshop or Lightroom, which can be a pain if you end up shooting HEIF images. In-body image stabilisation works in combination with lens-based optical image stabilisation (OIS) if the lens has this built-in. This can help give great results at slower than expected shutter speeds.

 

Canon EOS R5 ISO test images

ISO Noise Performance - Noise is very low and detail highest, at the lowest ISO speeds. Noise starts to appear at ISO3200, and fine detail starts to drop, with this continuing as you go up the ISO range. Images are still usable at ISO speeds up to ISO12800 and ISO25600 depending on your needs. ISO51200 shows the highest levels of noise, and the lowest levels of detail, and this speed is best avoided unless you have no other choice but to use this speed. ISO102400 is also best avoided, although it's worth noting that colour saturation remains quite good. 

 

Canon EOS R5 White-balance test images

White Balance Performance - Auto White Balance (AWB) gives a warm result under tungsten/incandescent lighting, with the "Cool" option giving a slightly more neutral result. The tungsten preset does a good job producing a whiter image, which will be useful for product shots. AWB performs well under fluorescent, and natural lighting. The fluorescent preset gives a colour cast.

 

Canon EOS R5 Digital filters

Digital Filters - The Picture Styles can be customised with options for sharpness (strength, fineness, threshold), contrast, saturation, and colour tone. We've shown the built-in styles, and there are a further three customisable user-defined styles.

 

Video - With such high video specifications available, it's worth noting how much space you'll need to record at the higher settings.

8K video recording is storage intensive, so a 128GB memory card will give you just over 12minutes of video recording. If you're shooting 8K RAW the camera is outputting 2600Mbps (6minutes on a 128GB card), 8K ALL-I is 1300Mbps (12minutes), and 8K IPB is 470Mbps (35minutes). High-quality 4K lets you record 33 minutes on a 128GB card. Some of the 4K modes also use very high data rates, with 960mbps. You'll need a seriously beefy computer, and appropriate software to edit the best of these.

The longest time you can record one clip is 29 minutes, and Canon has more details on recording here.

8K DCI recording is possible at 30/25/24fps, and has a 17:9 aspect ratio, while 8K UHD has a 16:9 aspect ratio, with a maximum recording time of 20 minutes. You'll need to use a CFexpress card to use the highest recording options. The camera also supports 4:2:2 10-bit recording.

High-speed 4K video can be recorded at 120fps, for playback at 30fps, giving you 4x slow-motion (without sound), with a maximum recording time of 15 minutes. High-speed FullHD video is also recorded at 120fps.

Recording 4K 60p, there's a time limit of 35 minutes (due to heat concerns), and at 4K/30p there's no limit due to heat. The 4K High-Quality mode records at (up to) 30fps, using an 8.2K oversampled image for improved detail, and there's a 30-minute heat limit. Once you've reached the time limit, you then need to wait a certain amount of time for the camera to cool down. (This may all change with future firmware updates).

If you do hit the heat-related time limits, you could quickly find this camera very frustrating to use, especially if you need to record video again, and don't have the time to wait 20 minutes for it to "cool" down. Once the camera has cooled down, then the recording time available is limited further.

Image stabilisation works well, and with a combination of in-camera sensor-based image stabilisation and optical image stabilisation in the lens, we got some very steady footage, even though we were simply holding the camera, without the use of a tripod. Auto-focus performance was good, and using AF tracking meant the camera successfully tracked the subject. You can also record 8K or 4K time-lapse video.

Video quality is excellent, autofocus performs well, exposure is reliable, and colour reproduction is particularly pleasing (with a little exposure compensation).
