Cool!   This is great news!  I almost bought the 1.4x III extender earlier this week because I was afraid the 2x extender would not work with some lenses on my 1DX.  Now the choice is simple!  I will get a 2x extender. 

Using the 1.4x will yield better optical quality than the 2x, and also with an f/4 lens and the 1.4x you have 21 cross-type AF points and 40 more single-line points, whereas with an f/4 lens and the 2x you have 1 cross type and 4 single-line points. 

So, budget permitting, having both makes sense to me.

But will it be red ONLY for AI SERVO? What about ONE SHOT? I don't servo in dark receptions.

They already illuminate in One Shot (provided you've enabled the setting to do so, the default is to only illuminate when the camera thinks it's dark enough to need it, but you can have them light every time with a setting change).  The issue at hand was that the point in use doesn't illuminate in AI Servo on the 1D X, as it did on previous 1-series bodies (but not on the 7D).

Are you saying the 1dx does light up at the START of AF in one shot, while the 5d3 does not?

No, I'm saying both the 1D X and the 5DIII can light up when focus is achieved (not at the start of AF, but at the end), provided the VF Display Illumination setting (AF5 menu) is set accordingly.

So the question is, when, in the name of everything, can I download?!

I can't say why I'm recommending this, but I'd strongly recommend trying the 1D X firmware update link again after 9 PM EDT today.

Concerning the f/8 auto focus - I ran into this on my 60D using a 100-400mm and a Tamron 1.4x teleconverter.  I was able to auto focus at f/8 and was surprised.

Was this a drawback on the original 1Dx firmware or a bump-up for the 60D on IT'S last firmware update?

Neither.  3rd party TC's have been variably able to allow AF at f/8.  Point here is this applies to Canon's TCs (some people have tried to get around it by taping over some of the contacts on the TC).

Not quite as good as Nikon's 51pt f/8 AF option

Erm, you mean 15pt f/8, don't you?  Sure, one f/8 cross-type point with 4 surrounding single-line f/8 points isn't as good as three full columns of cross points, but let's not inflate Nikon's system, mmmm'k?   :P

Isnt it common knowledge zoom lenses can never be as sharp as a fixed focal length? Zooms have to make compromises. always. doesnt matter what u pay.

It seems conventional wisdom went out the window when it came to reviews for the 24-70 mk. ii

Actually, it went out the window two years earlier, when the 70-200mm f/2.8L IS II came out.  Now, it's the new normal.   :P

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?

That's correct - and I'll be using it that way.  Plus, my 600/4 II will now AF with the 2x extender, and from the TDP ISO 12233 charts, the 600 II + 2xIII gives IQ a little better than the 800/5.6 + 1.4xIII, plus it's a little longer (1200mm vs. 1120mm). 

All around, I'm a happy camper.

Now nikon no longer has the F/8 AF advantage anymore.  8)

They still have many more AF points available with an f/8 lens.  Just sayin'.



Note that the press release was available this morning, but it has now been pulled from the Canon USA Press Releases page, and the firmware link is still not active. 

Seems like this was not ready for release from embargo yet (maybe planned for announcement closer to PhotoPlus?), and someone goofed and let it slip out early (or it was an intentional leak).

Still, this means we should see it sometime soon.  Later today, or if not, in a few days.

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.

Lighting / Re: Is it possible to radio trigger 580EXII with ST-E3?
« on: October 17, 2012, 09:34:01 AM »
thanks that means no choice but to move to canon's system right now... dang!

I wish I could, well...I might for outdoor use, I've already got one 600EX-RT.  But indoors I also need to trigger a monolight, and the Canon system doesn't help there.  :(  I'm still hoping for a Canon -RT receiver that can trigger an older Canon flash or a monolight.  I do expect we'll see one...but not until after a 430EX II replacement with radio slave capability is released, and sales of that slow down.

can i actually use the STE3-RT to tigger a FlexTT5 on 580EXII?

No, you'd need a MiniTT1 or FlexTT5 on the camera.

The reason why I'm asking is if this is a 24-70 mk2 issue, it's pretty useless... this is a very expensive lens and not that fast and should be almost no sample variation... I'd be pretty upset I think...

Agreed, and even though Canon had copy variability with the original, you'd think they'd have learned from that...

I was very interested in this lens when it was announced, but instead of pre-ordering it, I put those funds toward my 600 II.  Now, I'm even more happy that I did that.  I'm now actually considering the 50/1.2L instead of the 24-70 II.

-Mount the lens align target on a tripod and level it out.  I get it as close as possible to MFD.

That's a bad idea, unless you're always shooting at the MFD.  The adjustment at the MFD is often quite different from the adjustment at other focus distances, and once you get a ways out from the lens, the adjustment values tend to get much more stable.  That is why LensAlign recommends 25x the focal length, and Canon recommends 50x the focal length (i.e., about 8 ft and 16 ft, respectively, for a 100mm lens).

The keys to getting consistent results are a stable tripod and LOTS of light. Personally, I have 450 W of light pointed at the target from a distance of a little over 1 foot.

We also hope to find out about delays in production of the EF 500 f/4L IS II & EF 600 f/4L IS II, the last I heard we won’t see them until November.

Mt. Spokane previously suggested problems with fluorite crystal growth (a process which takes over a year for lenses that size) due to the power issues in Japan - that certainly makes sense.

They're obviously getting them out in limited quantities, as B&H got an allotment on 28-September sufficient to cover their existing preorders (including mine for the 600 II  :D ), and briefly list both 500 II and 600 II as In Stock on their website, before they quickly sold out again.

8880
What are everyone else's thoughts on the fact that you need to buy 5 copies to get one that meets the hype  Canon gave it and the quality a lens of this price would have one expect?

I think that when I get this lens, I'll be giving it some very thorough testing immediately upon receipt...and I'll be hanging on to the packaging...
