With Canon’s introduction of the high-resolution, full-frame 50.6MP CMOS sensor in the EOS 5DS and EOS 5DS R DSLRs, many photographers are wondering which model is best for them. Luckily, there is only one major difference between the two cameras, and that is the implementation of a low-pass filter (LPF) cancellation effect in the 5DS R.
Most DSLRs, including the EOS 5DS, use a low-pass filter to eliminate false colors and moiré that can be created when shooting finely detailed repeating effects or patterns, by splitting the light points before they reach the sensor. The use of this filter makes the EOS 5DS DSLR a good fit for most users, as it is suited to use in a wide range of applications. The EOS 5DS R uses a separate filter to cancel this effect, to capture the maximum resolution and sharpness possible, though at a greater risk of aliasing and moiré. This makes the 5DS R useful for photographers who have complete control over their scene, require the highest resolution possible, and/or have time to spend working on images during post processing.
