Canon has introduced the Canon EOS 5DSi and Canon EOS 5DS R Digital SLR
cameras. These new EOS models incorporate a newly designed Canon 50.6
megapixel full-frame CMOS image sensor and Dual DIGIC 6 Image Processors for
high image quality and processing speed.
Maximising the potential of the new 50.6 megapixel sensor – for the first time in an
EOS camera the low-pass filter effect in the EOS 5DS R model is cancelled. The
cancellation of the low-pass filter helps deliver sharp images, squeezing the most
out of every pixel.
Sharpness
In addition to the 50.6 megapixel full-frame image sensor and Dual DIGIC 6 Image
Processors, both cameras include a 61-Point High Density Reticular AF array
including up to 41 cross-type AF points and EOS iTR AF for high precision autofocus.
They also include the EOS Scene Detection system featuring a 150,000-pixel
RGB+IR 252-zone metering sensor that provides enhanced precision and
performance.
In support of such a high-resolution imaging sensor, the EOS 5DS and EOS 5DS R
cameras were designed to minimise camera shake and significantly improve
stability via a reinforced chassis, baseplate and tripod lug to improve rigidity.
Canon also re-designed the mirror vibration control system to help reduce mirror
bounce and camera shake. To help maximise stability and minimise vibrations,
Canon added a new Arbitrary Release Time Lag Setting in Mirror Lock mode in both
models. In addition to the standard setting (press the shutter button once to lock
the mirror, then again to release the shutter), the EOS 5DS and EOS 5DS R cameras
offer new setting intervals of 1/8, 1/4, 1/2, one and two seconds, releasing the
shutter after the selected preset delay, allowing potential camera vibration to
dissipate before shutter release.
A new picture style called “Fine Detail’ has been added to enhance the sharpness of
JPEGs and EOS Movies with three new settings: Strength, Fineness and Threshold.
With such resolution on each sensor, both models also provide two cropped shooting
modes, while still delivering high-resolution images 30.5 megapixels for the 1.3x
mode and 19.6 megapixels for the 1.6x mode. The available crop options are visible
as a mask or an outline in the viewfinder; so shooters can know exactly where to
frame their subject.
Capturing
Like the EOS 7D Mark II, the EOS 5DS and EOS 5DS R cameras feature an advanced
AE system that can detect and compensate for flickering light sources. When
enabled, this anti-flicker system automatically adjusts shutter release timing to help
reduce disparities in exposure and colour especially during continuous shooting. And
new Auto White Balance settings include Ambience Priority and White Priority (for
use when shooting under tungsten lighting).
Photographers and cinematographers will appreciate improved custom controls
including a built-in intervalometer and bulb timer to enable the capture of time-lapse images and long-exposure images. These features are ideal for recording
fireworks, star trails, sunrises and more.
Both models feature Intelligent Viewfinder II providing approximately 100 percent
field of view, while adding the ability to display cropped shooting frames and
superimpose a customisable selection of camera settings and data such as dual-
mode electronic level display and grid, as well as exposure, white balance,
metering, drive, image quality and AF modes.
The EOS 5DS and EOS 5DS R cameras continue the EOS Movie tradition with the
ability to shoot in 1080p Full HD up to 30p or 720p HD video up to 60p. A creative
Time Lapse Movie function, a first for EOS cameras, takes a continuous series of
still photographs and automatically combines them in camera into a Full HD movie
file. Interval adjustments can be set from one second to 99 hours, 59 minutes and
59 seconds. The number of shots possible range from 2 to 3,600 with a maximum
of two minutes and 30 seconds of playback time. In addition, high-speed continuous
shooting up to five-frames-per-second (fps) at full 50 megapixel resolution allows
users to capture fast action.
The EOS 5DS and EOS 5DS R cameras feature dual card slots for CF and SD
memory cards, including Ultra High Speed (UHS-1) SD cards. Built to last, the
cameras also feature a shutter durability rating up to 150,000 cycles, the same as
the EOS 5D Mark III.
