CANON EOS 5DS R
When Canon announced the release of the 5DS, it came in two versions, the EOS 5DS, and the EOS 5DS R, the latter being one without a low-pass filter for optimum resolving power. The headlining feature for both cameras is of course a new 50-megapixel sensor, which essentially puts medium format level resolving capabilities in a 35mm format DSLR.
Compared to the Nikon D810 and the Sony A7R II, the EOS 5DS R feels a bit more solidly built, but is actually a bit lighter and smaller overall than the D810. The interface will be very familiar to Canon users, and while slightly less intuitive than that on both the D810 and A7R II due to the extra number of presses needed, offers the handy Q menu that lets you easily adjust all the main settings.
Canon has included ‘M-RAW’ and ‘S-RAW’ capture formats that essentially give you a down-sampled version of what’s captured by the camera. However, it doesn’t seem as though shooting in these formats speeds up the camera in any way. The top continuous shooting frame rate remains at 5.0 fps regardless, so there doesn’t seem to be an advantage to shooting in either of the smaller RAW versions other than the fact that you’ll gain more storage space on your card if needed.
The Auto ISO function is now similar to what’s in the 7D Mark II, so you can pre-set a minimum shutter speed to allow before the ISO is increased, or set it to Auto and bias the selection to pick a faster (or slower speed). The camera uses the 1/focal length formula for choosing shutter speeds, so we’d recommend adjusting that in the settings if you go with Auto.
You’ll also find a slightly different slew of connectors on the side of the camera from the previous 5D Mark III, as the 5DS R gains a USB 3.0 port at the expense of a headphone socket. This probably affects movie makers more, but you do gain the ability to take time-lapse movies thanks to the implementation of an intervalometer.
The M-Fn button can be a little difficult to reach without looking.
