It doesn’t happen often. Canon pulled firmware 1.1.1 for the Canon EOS 7D Mark II because of the rare occurence of a communicstion error with the WiFi Adapter W-E1.

Canon advisory:

A communication error has been discovered when using the EOS 7D Mark II running Firmware Version 1.1.1, which version was released on April 27, 2017, in combination with the Wi-Fi Adapter W-E1.

Remote shooting with the Camera Connect App is not possible after connecting the EOS 7D Mark II to a smartphone via the Wi-Fi Adapter W-E1.
This error occurs for cameras that have been updated from Firmware Version 1.0.5 or earlier to Firmware Version 1.1.1
This phenomenon will not occur if the camera meets either of the two conditions below:

• If the camera has been updated from Firmware Version 1.1.0 to Firmware Version 1.1.1.
• If the camera was already equipped with Firmware Version 1.1.1 at the time of purchase.

We are currently making preparations to correct this phenomenon with the release of a firmware update in early June. In the meantime, the tentative countermeasure is as follows:

• Firmware Version 1.1.1 will no longer be available for download, and Firmware Version 1.1.0 will be made available for download again.
• Users whose camera is affected by this phenomenon are asked to download Firmware Version 1.1.0 and install Firmware Version 1.1.0 onto the camera.

We sincerely apologize for any inconvenience caused to customers, and we ask for your ongoing patience.

If you want the improvements and fixes provided in Firmware Version 1.1.1* applied to your camera, please contact the Canon Customer Support Center in your region and make a request for your camera to be re-updated to Firmware Version 1.1.1.
Firmware version 1.1.1 for the EOS 7D Mark II incorporates the following changes:

• Enhances reliability of communications when transferring images using Wireless File Transmitter WFT-E7 B.

• Corrects the phenomenon of Err70 which occurs with certain combinations of settings.

• Corrects the phenomenon in which in very rare cases the shutter can no longer be released.

• Enhances reliability of operations for specific custom function settings.

Firmware version 1.1.0 is available for Windows and Mac. If you have any enquiries, please contact us for further assistance.

The rumored update for the Canon EOS 5D Mark IV is here, and as it turns out most of the rumored, mouth-watering features supposed to come with this update were a well made hoax. The EOS 5D Mark IV gets C-Log, and Canon wants you to pay $99 for the firmware update. And you have to send in your camera.

Canon press release:

Canon U.S.A. Announces Canon Log Feature Upgrade for the EOS 5D Mark IV Camera

MELVILLE, N.Y., April 20, 2017 – In a move to help meet the demands of professional filmmakers, Canon U.S.A., Inc., a leader in digital imaging solutions, today announced the availability of a feature upgrade for the EOS 5D Mark IV DSLR camera that will add the ability to record with Canon Log. With this upgrade, the EOS 5D Mark IV can achieve a cinematic look similar to what can be achieved using Cinema EOS cameras, allowing it to serve as a second camera on a Cinema EOS shoot or to stand alone as a cinema camera. Current EOS 5D Mark IV camera owners can have the Canon Log feature upgrade installed for $99 at any of the Canon service centers across the U.S. starting in July. The camera will also be available for sale (body only) with the feature upgrade pre-installed starting in July, with an estimated retail price of $3,599.00*.
Canon Log uses the image sensor’s characteristics in a way that allows for a wide dynamic range, minimal loss of detail in shadows and highlight areas and an increased range of choices when color grading. Color grading options available with Canon Log include optimized color saturation, accurate colors with minor color bias, visual continuity and accurate skin tones.

Canon Log also works with and complements several EOS 5D Mark IV camera features including 4K shooting, Dual Pixel CMOS AF, high speed 119.9p shooting in HD and 59.94p shooting in Full HD. Additional features include Movie Servo AF allowing the camera to focus on a subject even when the shutter button is not used, the ability to register custom shooting modes in Canon Log and movie shooting in Canon Log on a compatible iOS® or Android™ device using the free Canon Camera Connect app1.

To learn more about the feature upgrade and how to get it installed, please visit usa.canon.com/canonlog5d4.

The EOS 5D Mark IV camera with Canon Log will be shown at the NAB show in Las Vegas, NV, April 24-27, in the Canon U.S.A., Inc. Booth #C4325 in the Central Hall of the LVCC. Follow Canon throughout the show on Instagram at @CanonUSA and Twitter at @CanonUSApro.
