B&H & Adorama Have the New Teleconverters in Stock
« on: December 21, 2010, 09:19:17 AM »

From B&H Photo

B&H and Adorama have the new teleconverters in stock. I have one of each on order.


B&H: Canon EF 1.4x III $499 | Preorder: Canon EF 2.0x III $499


Adorama: Canon EF 1.4x III $499 | Preorder: Canon EF 2.0x III $499


Worth an upgrade?


The Extender EF 1.4x III and Extender EF 2x III have been designed to complement the latest range of L-series lenses, matching their appearance and offering a visible differentiation from previous models. A carefully positioned lens release mechanism also makes it easy to mount the extenders quickly, reducing the time that the camera and lens are exposed to the environment. The extenders offer the exceptional build-quality expected from Canon’s professional products, and are resistant to both dust and water, allowing photographers to use them in extreme shooting conditions.


Canon seems to think so, I do expect performance improvements. Anything to speed up putting on and taking off the converters is very welcomed.

Not cheap, but it improves the performance of all your tele lenses - the more you have, the less the price per piece. :)

Using these will cause you to loose 2 stops on any lens it's coupled with, right? So if I used one on my 70-200 f2.8L IS II, it'll make it a f5.6?

The TC1,4 costs one stop, the TC2 takes two.
(You could stack two TC1,4 to get the effect of one TC2)

So your 70-200 would be either a 100-300/4 or 140-400/5,6.

I had one on preorder months ago but i figured if I waited this long I can and will wait to see if the price drops some. $500 is a lot.

Like many, I am hoping for some optical improvement of the new MK. III TCs, in particular the 2x TC.
However, I wonder how much potential for improvement there is actually left. Optically, TCs are probably quite simple, further, contrary to lenses, there are no moving parts, so there is also less potential for QC problems which a new version could help to get rid off.
After all, what a TC does is an optical magnification of the central portion of the base lens' image - no matter how perfect this magnification is, it will always also enlarge any flaws of the base lens.
What do you think, how far are the Mk. II 2x TCs away from "perfect", i.e., how much better can a Mk. III even be?

That's pretty much how the internet works these days.  All that research just a point and click away but easier to say it with confidence.

Canon EF Teleconverters Mk. III and EF 70-200 2.8 L IS II
« Reply #12 on: December 22, 2010, 05:55:10 PM »
the compatibility chart http://www.bhphotovideo.com/FrameWork/charts/canon2xExtender.html linked on B&H product description for the TC 2x III includes the following footnote:
------------
*2 If the EF 70-200mm f/2.8L USM lens is attached to an EOS camera having multiple focusing points and an Extender is attached to the lens, only the center focusing point will be usable for AF. 
------------

but the chart title on top is "Extender EF 2x II Compatibility Chart" ... not Mk. III

Would anybody know, whether or not this restrictriction exists on a 70-200 2.8 L IS II with TX 2x Mk. III [on an EOS 7D]? Thanks for your insights!

Didn't I read somewhere that the new TCs are meant to allow faster focusing with the new super-teles?

Of course, I could look up this source, but it's easier just to say it with confidence!

CANON SEEMS TO THINK SO?

For the life of me I cannot see anything that says Canon Extenders will improve preformance with the older lenses as you seem to imply. They do however make it sound that they will communicate with the new lenses to be introduced. I have no problem using the Version II extenders with my lenses and think the upgrade would have to be significant to spend that type of money on the new extenders.
