Hello ,several users in Spain, when they have updated the firmware to the newest version, the multiplier kenko now does not work, the camera is blocked... Check if the same thing happens you.
Thanks
Kenko TC's cause issues with all newer cameras, but only with certain lenses. Usually, its related to AFMA. Turn off AFMA and they work, but you get out of focus images. Kenko updates the firmware in their TC's, and puts a colored dot on them, a different color each time. So far, they have not solved compatibility issues that I'm aware of. Its been a issue for several years with the 5D MK III, but now a whold groupof photographers are upgrading from a 7D to the MK II and re-discovering the issues with newer cameras.
This is always a issue for third party manufacturers. When Canon adds a new feature, upgrades AF, etc, reverse engineered products suddenly do not work. The issue comes from the faulty reverse engineering.
Thanks, I will tell them...
but I am interesting too if somebody have the same problem here.
Its a years old subject, lots of posts here, but a long time ago.
The search engine can find them, search for Kenko Hang

Here are more. I really wonder why people buy them? They do work on older cameras, but eventually, most people move up to a newer one, and suddenly they can't use them.
