According to the Egami Blog, Canon has filed an optical formula patent for an EF 1000mm f/5.6 DO lens.
Incorporating diffractive optics into a 1000mm lens sounds like a match made in heaven. The patent details mention Tokyo's Oympic Games in 2020 which seems to indicate Canon's anticipated launch window for the lens.
Note: The printer comes bundled with Canon Photo Paper which qualifies it for the $250.00 rebate. The retail price of the printer will drop to $299.00 with the promo code applied, making the final purchase total only $49.00 after rebate.
That works out to roughly $8.33 per month for Adobe Photoshop CC and Lightroom CC. For what it's worth, I consider the Creative Cloud Photography Plan to be the best $10.00 investment I make each month. [Sean]

We wish to notify you that the AF functions of the following interchangeable lenses for Canon, which have been produced before May 11th, 2015 and have not had firmware updates installed by Tamron, do not function in Live View mode when used on the EOS-1D X Mark II which went on sale on April 28th, 2016 in Japan.

Color is not simply a physical property of an object. It is the relationship between light, an object, and an observer. Our brains manage and process this information at amazing speeds, leading us to barely even notice the conclusions and the adaptations that they have made. But, these same wonderfully adaptive qualities of our eyes can trip us up when we are capturing color or even simply trying to remember a color precisely. Understanding color perception can help you to get accurate capture-to-print matching, understand the pitfalls of color correction and even to pick out the exact perfect shade of paint for your walls.
We have found that some SIGMA interchangeable lenses for CANON are not fully compatible with CANON EOS-1DX Mark II, which was released on April 28th. When certain lenses are attached to this camera, exposure of the image may not be accurate.
We are sorry for the inconvenience, and we will make a further announcement on our website when specific details are finalized. In addition, please also refer to the below usage notice related to this announcement.
[Phenomenon] When the lenses listed below are used and either “Evaluative Metering” or “Center-weighted Average Metering” is selected in Metering Mode of the camera, the image could show some underexposure.

We are currently working on the firmware update for respective lenses, and the release dates will be announced later.
Usage Notice for customers who are using EOS mount SIGMA lenses on a CANON EOS-1DX Mark II
MO (Manual Override) function is unavailable with this camera (Full-time Manual function can be offered).
When using a SIGMA interchangeable lens for EOS, setting the corrections to [Disable] is recommended, as “Lens Correction” functions of the camera, such as Peripheral illumination correction, Chromatic aberration correction, Diffraction correction and Distortion correction, are not supported. If those functions are activated, the performance of lenses may not be accurate. This is not only for EOS-1DX Mark II, but also other camera bodies.
We appreciate your continued support for our company and products.
Note from TDP: Any firmware fix will either require the Sigma USB Dock or a trip to Sigma's Service Center to implement. If you don't already have the dock, I highly suggest picking one up. [Sean]
Note: For a more complete lighting setup, you may also want to consider the also-marked-down Bolt VB-22 Bare-Bulb Flash and Accessory Kit which includes an extra battery, various light modifiers and a radio transmitter/receiver.
