It has been stated in the past by conventional photographers that no one needs more than 12 megapixels. But when Nikon reignited the megapixel race with the D800, and with 250-megapixel cameras, pixels came back in the horizon once again. The Canon EOS 5Ds is the most awaited response from Canon to the new generation of super-high resolution full frame cameras like the Sony A7R and A7RII along with Nikon D800 and D810.
One thing which will amaze the user of 5Ds is just how quiet the shutter is. The lack of noise is actually a result of Canon re-designing the mirror vibration control system to help reduce mirror bounce and camera shake that keeps those 50-megapixel files sharp.
Gizmag said Canon EOS 5Ds tops out a continuous shooting speed of 5 fps (frames per second). It has a remarkable feat considering that it can do 510 JPEGs or 14 RAW files. Although this isn't a sports camera, there's nothing to stop you in capturing action with the 5Ds.
Canon photographers around the world were happy to learn the announcement of EOS 5Ds along with its identical twin, the 5Ds R. These are the highest resolution 35mm format DLSR cameras ever produced. The difference between the two is that the "R'' incorporates an optical low pass filter effect cancellation which is negating the effects of the low pass filter.
The Digital Picture reported that Chuck Westfall of Canon USA further explains the difference: "The EOS 5DS uses a conventional low pass filter design in which a single point of image data entering the filter is first separated into two points and ultimately into four points by the time the data reaches the image sensor. By comparison, the EOS 5DS R uses a different low pass filter design in which the single point entering the filter is first separated into two points and then the two points are merged back into a single point by the time the data reaches the image sensor."
