I went back and tried the 1Dx - 70-300L and 1.4 TClll combo. It does not report F8, rather 5.6. It does AF though it doesn't snap to focus, it sort of settles there. A confirmation beep is heard when it does achieve focus. My 5D3 with the old firmware behaves the same way. I haven't loaded the new firmware yet. Thought I'll let a few of you guys test it out first.
Thanks!
Ah OK, OK so maybe it is not possible to make it work with whatever chips are inside the TC III and 70-300L. I guess the Kenko manages to due to some sort of fancy spoofing chip inside of it.
It would be nice if Canon offered a force f/8 mode toggle in the firmware, but that is not something I'd ever count on happening, basically zero chance. That would be so awesome though of course (hint hint ). But usually only closer to mom and pop companies do that sort of thing.
OK, well I guess I'll eat bread for a few weeks and order the Kenko then hope it has enough quality to make it worth while (and that it really does f/8 and AF as some said on another site).
It's too bad the Canon stuff wasn't designed differently, but what can you do. Sounds like the firmware can't be blamed.
But it can be praised for offering f/8 with official Canon stuff and with Kenko.
Unless I hear otherwise.
