Canon has announced the development of the EOS-1DX Mark III – the latest in its line of top-tier professional EOS-1 cameras. While affirming its commitment to its professional DSLR range, Canon has also announced two essential professional L-series telephoto lenses in RF-mount for its EOS-R line of full-frame mirrorless cameras.

RF85mm f/1.2L USM DS

The RF85mm f/1.2L USM DS improves upon the previously-released RF85mm f/1.2L USM with an additional Defocus Smoothing (DS) coating. Ideal for portraiture, the bokeh on the wide aperture f/1.2 lens is further optimised with a proprietary vapour-deposited coating technology.

This ensures perfectly soft bokeh balls with smooth gradients, avoiding harsh rings that can detract from an artful image.

RF70-200mm f/2.8L IS USM

Completing the trinity of RF-mount zoom lenses, the RF70-200mm f/2.8L IS USM gives users of Canon’s full-frame mirrorless cameras access to a wide, constant-aperture telephoto zoom, perfect for portraits, nature, wildlife and sports.

In addition to built-in multi-modal Image Stabilisation (IS) that prevents shake by up to five stops (CIPA rated), the telephoto zoom also sports for the first time dual ultrasonic motors (Nano USM), allowing for quicker, quieter and more efficient focusing while maintaining a compact form. It is 27% shorter and 28% lighter than its EF-mount cousin.

Dual Nano USM also allows a minimum focusing distance of 0.7m, down from 1.2m.

It will have nine circular aperture blades and a total of 17 elements in 13 groups with two aspherical elements, one super UD (ultra-low dispersion) and four UD elements. Water and dust resistance prevents ingress of foreign material while its extendable design keeps the build compact.


With Canon’s EOS-1 series of flagship professional cameras at its 30th anniversary this year (2019), the brand has announced an update to the EOS-1D X Mark II released back in April 2016.

Few details are shared, but the EOS-1D X Mark III will feature a new proprietary CMOS sensor and image processor with greater sensitivity for better flexibility across different shooting conditions. It will support 10-bit HEIF still images, along with internal recording of 10-bit 4K 60p footage at 4:2:2 chroma subsampling with C-Log and RAW format.

Autofocus and auto exposure tracking will be supported at up to 16fps and 20fps via OVF and live view respectively. Live view stills photography will now be available with electronic shutter for true silent shooting in sensitive situations.

An improved buffer will also allow five times the maximum number of images captured in RAW.

AF has been improved in terms of speed and sensitivity with 28 times the effective pixel density at the middle of the sensor while shooting via OVF, with AF functioning down to lower light levels in both OVF and live view. With 100% vertical and 90% horizontal AF point coverage, a total of 525 are available for automatic selection.

These changes are augmented with software improvements such as a new deep learning algorithm that improves tracking performance.

Tethered shooting has been a challenge for professional photographers who need to access their captured images as quickly as possible, and the new Wireless File Transmitter (WFT-E9) in development at Canon aims to take this to the next level in conjunction with the EOS-1D X Mark III.

Improved from the WFT-E8, the wireless file transmitter improves on file transmission speed by more than two times, while providing a more seamless usage experience with improved UI.

Other thoughtful features aimed at the diverse needs of professional photographers have also found their way on to the EOS-1D X Mark III. On the rugged magnesium alloy chassis are back-lit rear buttons perfect for nighttime photographers and astrophotographers. The AF Start button has been redesigned to enable quick AF tracking setting without requiring the user’s finger to be released

Storage has been upgraded from CFast 2.0 to CFexpress with two memory card slots, and the LP-E19 battery will last longer with a revamped power management system.

On display at Photoplus at New York City between October 24 – 26 2019, the launch date and pricing of the EOS-1D X Mark III has yet to be announced.
