50.6 Megapixels Ultra High Resolution image
- Approximately 50.6 megapixel ultra-high-pixel Full-frame Canon CMOS sensor
- EOS 5DS R is designed with the effect of optical low pass filter cancelled¹, maximizing the sharpness and clarity of the ultra-high-pixel resolving power
- Dual "DIGIC 6" digital image processors
- Standard ISO range from 100 to 6400 (expandable to L:50 and H: 12800)
- 5FPS High Speed Continuous Shooting at full resolution

New designs and functions to ensure sharpness and details in ultra-high-pixel image 
- Adoption of new Mirror Vibration Control System (MVCS) which suppresses camera-shake blurring due to mirror motion in ultra-high-pixel image
- The rigidity of the tripod socket and surrounding parts have been improved to reduce camera vibrations caused by mirror motion
- New Picture Style ‘Fine Detail’ has been added to emphasis fine edges and material textures brought by the ultra high resolution
- Sharpness setting with ‘Fineness’ and ‘Threshold’ parameters in Picture Style for fine adjustment of sharpening effect

61-point AF system and EOS iTR AF to achieve high AF precision in ultra-high-pixel resolution
