Canon 400mm 2.8 II and extenders Firmware Update

[Zeb B]

Any chance engineering can update the lens firmware to include this lens? I would like to use my Epic to shoot 4K wildlife but use the Canon 1Dc instead since it has the firmware to drive the lens.

Hey Team RED,
Did I post this in the wrong section? Seems a reasonable request to get answered and we're coming up on 2 weeks since the OP. What's up?

I'm assuming that Build 5.1.29 covers the current version 400mm f/2.8L II. Any chance for getting the 2X III Extenders checked out now? Would be useful for all kinds of work.

I've been using my 2X III Extender for over a year on both Scarlet and Epic. AF, stabilization and lens data are all functional, what about it still needs to be checked out?

I'm not down with being a test pilot with the Terms & Conditions of the RED Warranty and all. Just want to see it on the Approved for Use List.
