THE 50 MEGA PIXEL
CANON 5DS R
So what is the main difference between the Canon "straight" 5Ds vs. the 5Ds r? It all esentially boils down to the low-pass filter in front of the sensor (chip). Without geeking out over the technology that goes into the process, the low pass filter was introduced years ago on DSLR technology for the main reason of reducing the moire' pattern on fabrics, patterns, etc. As you know, moire' (please pronounce properly..."mwah-ray" and NOT "more-ay") patterns are caused when the bayer pattern of the chip interferes with the pattern on "lined" materials such as clothes, fabrics and even printed, or screened, images. As photo sites on the sensor, improperly called pixels, were reduced in size they became small enough that the lenses did not pick up the patterns on such a small scale and were somewhat...softer. This softness helped break up the pattern and hence moire' issues were reduced. It should be noted that placing micro filters also helped this fact as well.
Be it known that NO single shot digital camera can claim 100% moire' free capture, it seems that the 5DS R with its 50.6MP sensor has a natural moire' cause based on photo sites alone. With the absence of the low-pass filter images appear to be sharper due to the lack of another piece of glass that filters the image.
If you find yourself with a moire' situation change the factors by getting closer or further from the subject. You may find that changing the angle of view will also help reduce moire' patterns as well.
Canon 5DS R
New 50.6 Megapixel Full-frame CMOS sensor
The EOS 5Ds r camera features Canon's newest full-frame CMOS sensor. At 50.6 Megapixels, it's the highest resolution sensor in the history of EOS. It captures 8712 x 5813 effective pixels, delivering images with an unprecedented level of realism perfect for large-scale commercial printing, fine art, significant crops and any number of other high-end applications. Thanks to this amazing sensor, engineered to work in concert with dual DIGIC 6 Image Processors, the EOS 5Ds r is a remarkable, high-resolution camera with impressive performance.
Low-pass filter effect cancellation
For photographers wanting the ultimate in high resolution capture, the EOS 5DS R camera has a low-pass filter* (LPF) effect cancellation. While a low-pass filter is useful to reduce color artifacts and moiré typical with digital capture, it also reduces detail at the pixel level. With the LPF disabled, the EOS 5DS R takes full advantage of the original resolving power of the camera's 50.6 Megapixel sensor. More detail is captured and retained in the original image, perfect for landscape and commercial applications where pixel-level detail is scrutinized and when the sharpest possible image is needed.
1.3x and 1.6x crop shooting
For still photography, the EOS 5DS R camera features the flexibility of a cropping feature that extends the shooting effect 1.3x and 1.6x. With 50.6 Megapixel capture, cropped shots are possible with plenty of resolution to spare. Images recorded at 1.3x (APS-H) are approximately 30.5 Megapixels (6768 x 4512) Large/Fine JPEG, while images recorded at 1.6x (APS-C) are approximately 19.6 Megapixels (5424 x 3616) Large/Fine JPEG. Image cropping can be displayed in the viewfinder either masked or overlaid with an outline showing the cropped area and spect ratios can also be defined, with the EOS 5DS R shooting in 1:1, 4:3, and 16:9 ratios, in addition to the default 3:2.
New Fine Detail mode in Picture Style
Taking advantage of its sensor's high-resolution capturing power, the EOS 5DS R camera has a new Picture Style called Fine Detail mode. Fine Detail emphasizes fine edges and patterns or textures by setting the camera's Sharpness sub-settings, fineness and threshold to their minimum and by lowering contrast settings as well. Prioritizing minute details in the image allows for better gradations, more detailed textures and fine edges for smoother, more polished photographs.
Time Lapse Movie function
An EOS first, the EOS 5DS R camera even has a time-lapse movie feature that takes still photos at set intervals and joins them to create a silent movie. Perfect for showing the moving clouds across the sky, growth of a plant, changes in scenery, the flow of people walking and more, the EOS 5DS R's Time Lapse Movie function creates professional-quality movies, in camera, without the need for a computer, saving precious time when out in the field.
