In February 2015, Canon announced the release of two new models, "EOS 5DS" and "EOS 5DS R", both boasting the highest pixel count in the EOS series. I will, in a series of four articles starting from this one, unravel the appeal of the two cameras. (Reported by: Ryosuke Takahashi)
Both the EOS 5DS and EOS 5DS R are developed based on the EOS 5D Mark III model. In the following, I will, by comparing with the EOS 5D Mark III, highlight the more favourable and enhanced specs. I will leave it to you to determine the ways in which the camera has evolved.
Double Card Slots
Format / Recording Media
CF card (Type I-compliant, compatible with UDMA Mode 7), SD/SDHC/SDXC memory card
* Compatible with UHS-I cards
As with the EOS 5D Mark III, the EOS 5DS and 5DS R both come with double card slots that support CF and SD cards. While the recording method remains the same as that of the EOS 5D Mark III, taking into consideration the huge data size, some additional features that will come in handy are [Record separately] for recording in the RAW or JPEG format, and [Auto switch card] to switch to the other card and continue recording seamlessly.
Dual DIGIC 6
Format / Image Processor
Dual DIGIC 6
Data output by the CMOS sensor with about 50.6 megapixels is processed at high speed by two DIGIC 6 processors that are placed parallel to each other. High-definition images are generated by the digital signal, which maintains a broad gradation of 14 bits after A/D conversion. While achieving a high resolution of about 50.6 megapixels, high-speed continuous shooting at a maximum of about 5 fps is also possible.
CMOS with about 50.6-megapixel
Image Sensor / Format
A new miniaturisation process that supports a resolution exceeding 50-megapixel has been employed. Despite the smaller pixel size with the increase in pixel count, the aperture ratio of the photodiode is enhanced, and gapless micro lenses compatible with the new sensor are also built in to achieve high-definition image quality with only a low level of noise.
Recording Format / Crop/Aspect Ratio
Supports crop shooting or shooting based on the aspect ratio setting
Full-frame, 1.3x crop, 1.6x crop, 1:1 (aspect ratio), 4:3 (aspect ratio), 16:9 (aspect ratio)
Both models are equipped with a crop function that enhances the telephoto effect by about 1.3 times (equivalent to APS-H format) and about 1.6 times (equivalent to APS-C format). A crop frame or mask corresponding to the respective magnifications appears on the viewfinder, which allows you to grasp the resulting image while shooting. Cropping is applied after the data of all pixels are read.
Image Processing during Shooting / Picture Style
Auto, Standard, Portrait, Landscape, Fine Detail, Neutral, Faithful, Monochrome, User Defined 1 to 3
A new menu option, [Fine Detail], is added for the first time to the preset Picture Style effects. This option reduces the [Fineness] and [Threshold] of sharpness, and excels at faithful and delicate expression of the actual object with a relatively subtle [Contrast] setting (compared to the [Standard] contrast).
AWB (Ambience Priority)
Image Processing during Shooting / White Balance
Supports Auto (Ambience priority), Auto (White priority), Preset (Daylight, Shade, Cloudy, Tungsten, White fluorescent light, Flash), Custom, Colour temperature setting (approx. 2,500 to 10,000K), White balance compensation, White balance bracketing
* Supports communication of the flash's colour temperature information
Scene detection ability is further enhanced on the EOS 5DS and EOS 5DS R. [Auto (Ambience priority)] and [Auto (White priority)] are newly added to the AWB menu. In the [Auto (White priority)] setting, influences from light source colours, such as that of tungsten light, are eliminated to enable reproduction of white colour in white.
Exposure Control / Metering Mode
Uses an RGB + IR metering sensor with about 150,000 pixels for 252-zone TTL full-aperture metering
EOS iSA (Intelligent Subject Analysis) system
- Evaluative metering (supports all AF points)
- Partial metering (approx. 6.1% around the centre of the viewfinder screen)
- Spot metering (approx. 1.3% around the centre of the viewfinder screen)
- Centre-weighted average metering
The AE system uses an RGB + IR (infrared) metering sensor with about 150,000 pixels for 252-zone TTL full-aperture metering, and it supports the EOS iSA system. These features help to boost the basic performance of the camera including its AF. Besides support for colour tracking and anti-flicker during shooting, metering accuracy under artificial light sources is also enhanced.
Custom Quick Control
Customisation / Custom Quick Control
Users can customise the Quick Control screen according to their preference. Items can be selected and pasted, and you can also alter the position and size of the icons. The customised screen is saved separately from the default layout, so you can choose which screen to use according to your needs.
