Canon EOS 5DS vs. EOS 5DS R
While sharing the same 50.6 Megapixel sensor the photographic capabilities, the difference between the EOS 5DS and the EOS 5DSR cameras is EOS 5DS R's low-pass filter cancellation effect.
LPF Cancellation (EOS 5DS R)
While the LPF's purpose is to minimize the moiré and false color artifacting inherent in digital imaging, it does reduce resolving power of the sensor. The EOS 5DS R camera's LPF cancellation effect delivers greater sharpness and finer detail, useful in specialized situations, but the possibility of moiré and color artifacting is greater however. Fortunately, there are methods to help eliminate these effects while capturing and during post-processing.
imaging possibilities for photographers who produce large, highly-detailed prints and those looking to do extensive, creative cropping. These two cameras are very similar, but determining which model is right for you largely depends on your application. For most users, professional and advanced enthusiasts alike, the EOS 5DS will be the ideal choice, and is suited for a wide range of applications, including studio, landscape, gallery and fine-art photography, and more. The EOS 5DS R is a specialized version and is intended for photographers looking to capture the maximum amount of detail possible, and is best suited for landscape, commercial work, or other specialized types of applications. Since the EOS 5DS R offers the LPF cancellation effect, the possibility of moiré and color artifacts is greater than with the EOS 5DS.
