*UPDATE* Canon EOS-1D X Firmware Update Addresses f/8 & Red AF Points in AI Servo

+1 on 5D3 getting the red.

I don't think Canon will 'premiumize' this and withhold it from the 5D3.  It's a clear miss on a pro body, and people will clearly not pay 2x the 5D3 price to get red AF points.  I'm confident this will be rolled out to 5D3 as well.

Hopefully they will get this out for the 5DIII as well.

+1 for the 5DIII.  Urgently needed.  This has been a feature on every EOS body up to the 5DIII and 1DX, so I don't think they will make it a "premium" feature exclusive to the 1DX.  I hope there is no technical problem with implementing it on the 5DIII.

My only fear is that they haven't released it at the same time because the difference in the extra processor for 1DX allows for recalculating exposures with the red AF point. Hoping someone with more technical knowledge can allay my fears.

It is possible to see f/8 AF for the 5D3 considering the D800 has it.

I hope to see a 4K firmware for the 1DX soon. The 1DC is identical internally to a 1DX.

<p><strong>Cross-Type AF Support at f/8<br />

The new firmware allows cross-type autofocusing with the center AF point even when the maximum aperture of a Canon EF lens/extender combination becomes as small as f/8. Ideal for wildlife photographers and others who often use EF super-telephoto lenses with extenders, this new feature greatly expands the range of EF lens/extender combinations that support autofocus when used with the EOS...

Since the D600 has AF support at f/8 I hope that the 5D III and the 6D will also get such a Firmware Update.

Yes, there's no reason why the 5D3 can't have the same..BUT i highly doubt Canon will do it for the 5D3..that way if you REALLY want it, you gotta buy a 1DX…smart marketing from Canon i must say..

possilby on the f/8 side of things you may be right. but not for the red AF points...as that's a work around to correct something that is clearly an issue for many photographers.

Unfortunately you're probably right on the f/8 AF side, people will still have to keep doing the work-arounds. For the red AF points, they better bring that to the 5d3. Target market is wedding & others who shoot in dim lighting. The 5d3 is a prime choice for many of them.

More for the f8 AF. My need that is...

[Sitting Elf]

If I'm reading this right, I will now be able to extend my EF100-400 f/5.6 with a 1.4 extender, giving me effective 560mm at f/8... AND will now autofocus on my 1DX???

Is this right?

[AprilForever]

Indeed. Now, may the 7D mark II do the same...

[tron]

Oh Yes! and.. Oh No! I have a 5DIII and I am getting impatient already ...

[facedodge]

Obviously, there are a lot of 5D3 users reading this website... I am one more...

Tell you what though, I'd trade exposure compensation with Auto ISO for Red illuminated AF points.

I've already become accustomed to the work around by hitting the M-Fn button when I lose the point.

[AvTvM]

i want it for my 7D as well. Both features, f/8 cross-type center AF and red-lit AF-üpoints in servo AF.

Come on Canon, its only firmware .. dole it out. And make it quick!

Finally, a thread that unites us all 

[Mt Spokane Photography]

Thank you Canon.
But makes me wonder why this was not provided initially.
Beter late than never...

+1. 

I literally almost bought the Kenko 1.4x yesterday, to try out with the 100-400mm for those times when I can't bring the 600/4 II.  Now that the Canon 1.4xIII will soon give me AF, I've just ordered the 2xIII (to replace my 2xII) for use with the 600/4 II.

Side note - the Kenko remains a viable option for those with a 70-300 L, which is physically incompatible with the Canon TCs.

My Kenko 1.4X TC is still within the return window, but I'll keep it.  As noted, it works at f/8 with many lenses that do not accept a canon TC, and even focuses at f/8 with my old 10D!
I do hope they release a similar fix for the 5D MK III, but they will likely delay, if only to find out about any bugs once a large number of users have the firmware.

I don't think that's an issue as the metering still takes place with the AF points off:

To preserve exposure-metering accuracy, illumination is intermittent, not continuous.
