Conceptual Diagram of Low-Pass Filter Effect Cancellation5DS manual is here at Canon Europe
On the EOS 5DS R, the image of the subject is first separated in the vertical direction by Low-pass Filter 1, after which the separated images are merged again at Low-pass Filter 2. In the case of the EOS 5DS, the subject image is separated in the horizontal direction by Low-pass Filter 1, and in the vertical direction by Low-pass Filter 2.
A newly-developed full-frame CMOS sensor is employed on both models, but they vary significantly in the structure of the low-pass filter that is located immediately in front of the image sensor. As with the other EOS models, the EOS 5DS prevents false colours and moiré effect from occurring by separating the subject image using the low-pass filter effect. In contrast, the EOS 5DS R separates the subject image with the low-pass filter, but merges them again using a technology uniquely developed by Canon. Doing so successfully cancels the low-pass filter effect to achieve an apparent resolution that is similar to that when a low-pass filter is not used. Other than the optical LPF feature, the EOS 5DS R and the EOS 5DS are basically twins with no difference in their functions and mechanism. Various measures have also been introduced on both the hardware and software of the two models to address camera shake, an issue that may become more pronounced with a high pixel count that exceeds 50 megapixels. In the following, let us take a look at these two cameras with “super high” image quality.
Shutter time lag can be set manually
Unlike conventional models, the shutter time lag after the mirror is locked up can be set manually. By selecting an interval setting, both the mirror lockup and shutter release operations can be performed successively with a single press of the shutter button, thus helping to reduce camera shake.
both beneficial to getting ultra sharp images. I am keeping a close eye on this camera, I have not yet decided if I will pull the trigger on it, or a new lense. I will keep you posted when news and reviews become available.
