1.4x or 2x?

I've tried both, but only own the 2x II

Anyone who owns one of these know their limitations and would rather use a longer prime. As a cyclist and nature lover: backpack weight, size and versatility of what's in the bag are just as important as "pixel-peep-proof" quality.

I'm not one to pick fights and value the comments in this excellent thread. I have read you cannot use a 2x for BIF. I'm guessing this is due to AF speed whilst tracking a fast bird. Well...

Hobby - one fast BIF for 2x AF?
One of the fastest and most manoeuvrable falcons is the Eurosian Hobby. With a 7D in centre spot, I had a great night tracking and tacking these amazing raptors with the 2x fitted. I don't know of a more difficult bird to track (100mph 160 kmh), and I got a good deal of keepers. It was sunset and into the light, but quite a nice capture:

2X perfect?
No. Would love a 300mm f/2.8 II IS. The money is in the bank - not earning much interest. But that's not the point. I would need to get much fitter and stronger to enjoy my cycling / photography lugging even more equipment around.

Sometimes it's case of being honest, and asking if ultimate quality is what you actually need or simply crave. For myself, I enjoy the challenge of getting the most out of a 70-200 and 2x combination. More often or not, that means F8-F11 and getting busy with the centre-point focussing!

The 2x does well on the 70-200 II.

+1 (2x mk 3 that is)

its also very good on the venerable 300f4L IS

I agree with Neuro the 2XIII works great on the 70-200 II if you can live with F5.6 wide open.  Sweet spot with the combo is around F/8.  Note also that the AF speed drops...not by a lot but it is noticeable.  Birds in flight can be a challenge for it but not impossible.  You wont be happy with the reach using the 1.4X.  Where the 1.4 comes in handy is when you are using the Large tele's 300MM and higher.

Eastwind nailed it...my thoughts exactly.

I recently bought a 70-200 2.8 L II and then sold my 70-300 L. Tooking advantage of this sell and buying a 2x III extender was a big wait for me.

I recently had the opportunity to give the 2x III a try on my 70-200 2.8 II during a Canon show... and I was damn so disappointed !
I compared many shots @200mm f/2.8 vs @100mm+extender f/5.6 and I found the difference was more than noticeable in terms of sharpness in favor of the shots made @200mm f/2.8.

The Canon salesman couldn't agree more... he admitted the 1.4x & 2x extenders were not made to be combined with any 70-200 lens ! Their purpose is to be mounted with the long prime lens such over 300mm. Especially the newer versions III.

Honestly, I'm getting lost when I see some people posting sharp pictures with the 2x III - 70-200 2.8 L II combo.  :o
Please don't tell me Canon gave me a bad copy of their extender...

You can make considerable correction to sharpness with DPP or Photoshop.  It wont be the same as without the extender but it can help.  You also need to make sure that it is focusing properly with the extender on.  There are some variations between cameras lenses and even the extenders themselves and the error can compound if all three are just off by a small amount.  Try manual focus using live view with 10X magnification and see how it compares with using just the center AF point in normal AF mode.

Also, the sweep spot for that combo will be around F8 for the best possible image quality.

The combo should less sharp than the bare 70-200 II, but still quite sharp.

Example with the 5DII:

EOS 5D Mark II, EF 70-200mm f/2.8L II IS USM + EF 2x II Extender @ 260mm, 1/250 s, f/5.6, ISO 400

Example with the 7D:

EOS 7D, EF 70-200mm f/2.8L II IS USM + EF 2x II Extender @ 400mm, 1/160 s, f/5.6, ISO 3200

If your not getting sharp images, the first question I'd ask is if you've done an autofocus microadjustment.  Do note that the AFMA needs to be done separately for the lens + TC combo.
EOS 1D X, EOS M, and lots of lenses

I use the 2x with the 70-200 on the 5D3 and find it very good. Although the setup is a bit on the long side when you have it on there.

I never used it much with the 7D a camera that I really liked, with any lens. I think these latest TC's really only work to their best with the latest generation of lenses and cameras. But as show by Neuro above, they can produce good results.

If you debate with a fool onlookers can find it VERY difficult to tell the difference.

I use a Tamron sp pro 1.4x on the 70-200 II... just fine

but the 2x III is fairly good..... on that lens too

having f8 NOW, on the 5D3, also allows me to use the 2x III on my 70-200 f4 I.S. ...
but the native lenses are much better in focus speed and clarity

I have both and routinely use the 1.4 while avoid  the 2x - perhaps because I put this on a 500 F4 which makes it F8 which is hard to focus.  I have a mix results with the 2x, I think the problem is with the photographer, not the equipment but it is much harder to use the 2x on an F4 lens than it is to use 1.4x

I have spent much time using either TC on 2.8
