Canon EOS 5DS R Review : Performance

Canon EOS 5DS R 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.

Speed - We took a number of shots to test the camera's responsiveness, from switch on to first photo, shot to shot, focusing speed etc. We take a number of shots and then use the average to ensure accurate and consistent tests, making it easy to compare with other cameras.

Shutter Response 0.05secs
Wide - Focus / Shutter Response 0.3secs
Full zoom - Focus / Shutter Response 0.15secs
Switch on Time to Taking a Photo 0.8secs
Shot to Shot without Flash 0.35secs
Shot to Shot with Flash N/A
Continuous Shooting - JPEG
(shots before slow down)
5fps (26 shots)
Continuous Shooting - Flash N/A
Continuous Shooting - RAW 5fps (12 shots)

Tested with the 16-35mm lens, with lens aberation correction enabled and disabled (with the same results), and a Toshiba 1066x UDMA7 EXCERIA PRO CompactFlash card, as well as a high speed SD card (with the same number of shots possible before slowdown on both cards the same).

Canon EOS 5DS R Sample Photos

Sample Photos - The camera produces photos with good colour, pleasing skin tones and lots of detail. Exposure is reliable and dynamic range is reasonably good, although to boost shadow areas you can adjust the "Auto Lighting Optimiser" setting. Using the HDR mode there are a number of options available, from natural to artistic, or alternatively you can process the raw files to recover any lost highlight or shadow detail. 

Canon EOS 5DS R Lens test images

Lens Performance - Using the Canon EF 16-35mm f/4L IS USM, Canon EF 50mm f/1.4 USM, and Canon EF 135mm f/2L USM lenses, we were able to take sharp detailed images. Built in lens aberration correction will correct for peripheral illumination (vignetting) plus chromatic aberration for Canon lenses where the camera has correction data available. As a result vignetting and chromatic aberration / purple fringing is very low and should not cause any problems. JPEG images range in size between 15MB and 28MB, and raw files can be between 60MB and 73MB, and a large and fast memory card is recommended.

Canon EOS 5DS R ISO test images

ISO Noise Performance - For the lowest noise and best detail possible we would recommend using ISO50 to ISO1600, as images have low levels of noise and good levels of detail. For lower light situations ISO3200 still provides good results, although noise increases and detail is reduced. At ISO6400 noise levels become strong and we would recommend avoiding this setting if possible, although results may still be useful if resized and used on the web. ISO12800 is best avoided as noise is high, and detail is reduced. Shooting using the extended ISO mode of ISO50 results in an image with lower dynamic range making it easier to experience blown and overexposed highlights. 

Canon EOS 5DS R White-balance test images

White Balance Performance - Auto White Balance (AWB) performs well under tungsten lighting, with the tungsten preset giving a more accurate result. AWB performs very well under fluorescent lights, with the fluorescent preset giving a slight magenta colour cast. Options include Auto White Balance Ambient and White priority. 

Canon EOS 5DS R Digital filters

Digital Filters - There are a number of preset picture styles available, along with three custom picture styles that can be setup with your own preferences. The options available include Sharpness (strength, fineness, threshold), contrast, saturation, and colour tone. Auto lighting optimiser boosts shadow detail, and there is a "Highlight Tone Priority" option to avoid blown highlights. A built in HDR shooting mode is available that combines a number of shots for enhance dynamic range, and there are several options available for a more natural effect, or alternatively for a more artistic result. 

Video - The Canon EOS 5DS R has a number of video options, including Movie Servo AF, AF tracking, Grid display, Time code, Silent control, Time-lapse movie, Microphone level, plus Wind filter / attenuator options. The highest ISO available in video mode is ISO6400. For professional video recording, you may be better off with the Canon EOS 5D Mark III, as this has a headphone socket as well as clean HDMI out. Canon explain that clean HDMI  wasn't included with the 5DS and R due to an increased chance of moire and skewing.

I own this camera and have been using it for a month. I find it exceedingly comfortable and familiar though the menus are extremely detailed..more than I want and I essentially shoot the way I,would have with a film camera of days past with shutter priority and central 9 point focussing as I have been at this a long time. I do have definite and certain comment about lens quality. Because the sensor produces a huge raw file dimension of somewhere around 19 by 28 inches at 300 dpi it OS as of one has a contact print right out of the camera and therefore I have found lenses have an easy time of it resulting in extraordinary optical quality with every lens I own from the Al lenses down even to a Sigma 125-400 zoom which was. To known for super resolution but competent. I have tested all my assorted lenses with this camera. They are all flcussing well and since I work as a standard as a resized 24 byn36 inche 300 dpi image I can attest I have seen only improvements in the files from all the other canon cameras heretofore used. Rather than the lenses failing under the unblinking eye of a high resolution sensors quite the opposite is the result. The low level,of needed re sampling for me gives me a jaw dropping crystalline clarity and detail never seen from any of my lenses before. Further extremities of cropping result in images that were like an unresampled 5 D Mark II full frame images!!! Astonishing it is...I presumed I would have to upgrade some lenses or another but no! The soft mirror response has made handholding of this camera even with a long lens a no brainer so long as it has image stabilization. This was not always the case with my 5D Mark II.
Conclusion is, don't sweat feeling the need to replace your lenses in the purchase cost of this new camera. It is a wonderful breakthrough.

Not sure I would agree about the noise based on your test images. Despite having 5x as many pixels the image at 12,800ISO looks far less noisy than my 40D does at 1600. Sometimes I think you guys are spoiled by todays ultra low noise sensors...

Elsid any camera in the world would at 12800 compared to 1600 it's plus 4 stops .. so it's not even a comparison it's like saying my vw beetle pulls away faster than the ferrari when your in first and the ferrari starts in 5th ...
