It may well be the extender that needs the firmware update.
What firmware is your camera running ?
Well there was no firmware version 1.06 for the 7d mk2, so its definitely not talking about thatWithout the extender fitted, In the firmware section of camera it says (lens firmware 1.06 needed)

canon says - no firmware available

Has the issue started since you upgraded the firmware?
Are you sure the upgrade went in correctly. What was your original version?
The problem is caused by the Kenko extender, so why do you expect Canon to help you?Tried ringing Canon all morning cannot get through permanently on hold set up call back on there advice system still nothing.
Getting peed of now just under 2 grand spent not even 3 weeks old and no dealer or canon can/will help

You wouldn't get this issue if you used the lens on its own or with a Canon extender.
No real solution but you're not the first to have a problem with this combo.

Hi, I believe there is a potential issue with using the Kenko 1.4X PRO 300 Teleconverter DGX with the Canon 7D II as well as the 5DIII, 6D, 70D, and IDX with the current 100-400L as well a number of other older Canon lenses. The issue is that the camera hangs if per lens Micro Adjustment is turned on. The fix involves removing the camera battery and lens with the teleconverter and restarting the camera with out the converter. To avoid the problem you can turn off per lens Microadjustment before mounting the lens with the kenko to the camera. If you need microadjustment for the 100-400 with Kenko you can dial in the value by using the microadjustment "for all" setting. It just means that you have to member reset the microadjustment setting when using the 100-400L with kenko. The issue would not affect your T1i but might be an issue with the 7DII. Kenko gave me a refund for a converter when I ran into the issue on my 70D about a year ago. At that time they told me they did not have a converter that would avoid the issue. I don't know if they have made a change in the last year to address the problem.
No idea of it works or not though.
Thanks and yes im aware of the incompatibility of these 2 components, I was more concerned of the lens firmware update without the Kenko fitted but that has been resolved now by Canon
Sorry, did I miss the solution? What did Canon eventually advise that solved it???
I'm not sure there was ever a problem, apart fromSorry, did I miss the solution?
The problem is caused by the Kenko extender
that pic doesn't say it is needed it says, as needed. it shows 1.06 is already on the lenshere is the exact procedure pic 1 show update needed pic 2 shows memory card required with correct details needed View attachment 105585 View attachment 105586
I think you are misreading that page... It's simply showing you the current firmware installed along with a (suspect default) message to update firmware *as needed*... not "update required/needed."Sorry about the delay have spoken with several camera dealers and they dont have a clue either. Below is a screenshot showing update required all be it for camera firmware but if i highlighted the lens firmware i get the same message to update lens firmware.
Have this very morning tried the lens on my 6D and this is the same asking for lens firmware update 1.06 required.View attachment 105584
All canon lens that have the ability to have a firmware update will show the current level in the firmware settings in camera only when said lens is fitted, Thus you check for an update on Canons web site.
