Canon EOS 5Ds (R) press release
The big thing here is the use of a 50.6 MP sensor, enabling higher reolution images to be obtained when using good technique and good lenses. Apart from the sensor resolution, there's nothing really new here in terms of EOS 5D camera features. The 5DS R is capable of the highest resolution due to the effective removal of the low pass filter in front of the sensor. It doesn't actually have the low pass filter removed, rather it has a second filter installed the cancels the effect of the low pass filter. I believe this is the same strategy that Nikon used in their high resolution D800E. I'm guessing that this is because the low pass filter is actually bonded to the sensor, so it's easier to use a second filter to cancel out it's effect than to remove it. The point of doing this is to increase resolution (though at the risk of introducing more moire effects on high frequency detail).
Although there is no price listed here, prices have been quoted on other european sites. The 5Ds was listed at 3400 euros and the 5Ds R at 3699 euros. By comparison the current EOS 5D MkIII is selling for around 2500 euros. Since the 5D MkIII price in the US is around $3000, it looks like the 5Ds should retail for around $4200 here if the same relative prices hold. That would suggest that the 5DS R will probably be closer to $4500.
UPDATE
Well, the US prices are even lower than I'd estimated. The price at release will be $3899 and the price will be $3699. Delivery should start in June. As of June 2017, the price of the EOS 5DS-r is around $3700 and the 5DS is around $3500, so prices are holding up well!

Canon revolutionises resolution with the EOS 5DS and EOS 5DS R
London, UK, 6 February 2015 – Canon today transforms the EOS system with the arrival of the EOS 5DS and the EOS 5DS R – a new breed of ultra-high resolution full-frame DSLRs.
Breaking the boundaries of 35mm sensors,the new cameras offer the highest megapixels ever seen in a full frame sensor, an astonishing 50.6MP. Delivering unparalleled quality, the cameras provide an exceptional combination of resolution, responsiveness and durability, whether shooting landscapes, architecture, high fashion or portraiture, either personally or professionally. When nothing but the sharpest image is expected, the EOS 5DS R also features a low pass cancellation filter to maximise the sensor’s resolution and visible image quality.Alongside the new DSLRs, Canon also introduces the EF 11-24mm f/4L USM, the world’s widest-angle rectilinear zoom lens(1), the perfect companion for landscape and architecture photographers.
Establishing new standards for full-frame DSLRs
Setting a new benchmark for full-frame cameras, the EOS 5DS and EOS 5DS R combine fast, instinctive DSLR handling with the newly-developed 50.6MP CMOS sensor, providing the flexibility to shoot a wide range of scenes and subjects, making it ideal for large format mediums, such as advertising billboards and magazine covers, where every pixel matters. The sensor’s advanced architecture provides
ISO 100-6400 sensitivity, further expandable to 50-12800, ensuring high quality images with low noise, accurate colours and wide dynamic range.
For added flexibility, the cameras’ resolution enables three new in-camera crop shooting modes–1.3x, 1.6x and 1:1. Visible through the viewfinder, the crop modes deliver outstanding results, with stills at 19 MP even when cropped to 1.6x. Built to withstand the most demanding shoots, the EOS 5DS and EOS 5DS R’s dual DIGIC 6 processors provide the rapid performance and responsiveness required to deliver first-class images with exceptional colour reproduction. Both processors are designed to comfortably manage huge levels of image data from the 50.6MP sensor, whilst simultaneously reducing image noise and providing the freedom to shoot at five frames per second.
Automatically exceptional
Created to ensure every detail of your exquisite landscape or high-fashion studio shoot is in focus, the EOS 5DS and EOS 5DS R feature an advanced 61-point AF system, with 41 cross-type points, delivering incredible levels of image sharpness and accuracy across the frame.
Both cameras comfortably maintain focus with moving subjects, using EOS Intelligent Tracking and Recognition AF (iTR) to track both faces and colour. To reduce image blur, Canon’s Mirror Vibration Control System uses cams to drive the cameras’ mirror up and down in a highly controlled fashion, avoiding all sudden stops and softening the shutter-release sound. Additionally, the EOS 5DS and EOS 5DS R’s 150k pixel RGB+IR metering sensor with Flicker Detection ensures images can be captured with consistent and accurate exposures under varying lighting scenarios, including fluorescent.
Incredible detail and unrestricted creativity
Putting unrivalled image quality at your fingertips, the EOS 5DS and EOS 5DS R include a number of customisable modes and settings to ensure stunning results every time. A new Fine Detail Picture Style maximises the level of detail that can be achieved from the sensor, enabling advanced sharpness adjustment without the need for edit ing software. Popular creative modes, including Multiple Exposure and HDR, provide instant, in-camera creativity, while a built-in timer allows you to shoot over long periods and create stunning time lapse videos, without being tied to the camera or needing advanced software and excessive kit.
First-class professional construction, customisable features
The EOS 5DS and EOS 5DS R have been expertly constructed to allow you to operate quickly, regardless of the environment you’re shooting in. The 100% viewfinder with electronic overlay makes framing vital shots easy and can be customised to your preferred style. The large, 8.11cm (3.2”) Clear View II LCD screen, with an anti-reflective structure, minimises reflection or glare when reviewing shots and also acts as a visual and accessible dashboard of the most commonly used settings. The cameras’ new Custom Quick Control screen means that the type, size and position of icons are also easily customisable to the user or shooting scenario. Both cameras utilise Canon’s iconic design DNA–a highly durable body constructed from high-grade magnesium alloy to provide weather resilient shooting – ideal for landscape photographers who are dedicated to getting the perfect shot, whatever the weather.
EOS 5DS R: Engineered for the ultimate in DSLR image quality
When nothing but the absolute maximum level of detail possible will do, the EOS 5DS R features a low pass cancellation filter to ensure the sharpest possible results. Great for landscape photographers, where patterns are very often organic, the camera’s low pass cancellation filter produces the stunning level of detail required to turn a great shot into an incredible shot.
Optical Expertise: Introducing the EF 11-24mm f/4L USM
The EOS 5DS and EOS 5DS R are compatible with Canon’s extensive EF lens range, spanning 71 models(2). Today Canon unveils the world’s widest-angle rectilinear zoom lens (1), the EF 11-24mm f/4L USM. Perfect for photographers shooting landscape and architecture, the EF 11-24mm f/4L USM is designed to open up an entirely new world of creative opportunities, thanks to its super wide 11-24mm focal range. Boasting a newly designed optical structure, the lens features three aspherical lenses including a ground aspherical element, which maximises image quality and delivers minimal levels of distortion, while the body is rugged and robust enough to be employed in extreme weather conditions.
