The EOS 5DS R camera offers the potential for even greater sharpness and fine detail for specialized situations. It features the same Canon designed and manufactured 50.6 Megapixel sensor, with the low-pass filter* (LPF) effect cancelled to provide even more fine edge sharpness and detail for critical subjects such as detailed landscapes, and other situations where getting the sharpest subject detail is a priority.
LPF (Low-pass filter) effect cancellation takes full advantage of the original resolving power of the 50.6 effective megapixels CMOS sensor, delivering even higher resolution images.*
The key difference between both the 2 cameras is that the Canon 5DS-R introduces another low pass filter to cancel the effect of the first low pass filter. This is called the Low Pass Filter (LPF) Cancellation Effect. This will reduce the incidence of false color. This feature is not available with the Canon 5DS model which adds a little bit of blur to its photos.
This filter is located just behind the IR filter. It realigns original pixels that were shifted by the first filter and in turn, provides us with a sharper high-quality image even further without blur. For photographers who need a sharp, crisp images such as the landscape photographers and fine art photographers, this camera is the relevant choice.
