Teleconverters 1.4x advice for new Canon cameras: 6D

H . JM , Dec 13, 2012; 09:00 a.m.

Hello people;
SO I took the plunge and ordered the Canon 6D and I am glad I did; even though haven't come yet!
Now I want to get into some bird photography; nothing serious, just with my 70-200 F4 IS. I was planning initially to get the Kenko 1.4x as it had the best reviews out of any 3rd party TC
the problem is; some 5d iii users have put many posts about that TC not working on their camera, though it works on older cameras just perfect. I suspect it might be the case with 6D
the canon TC 1.4x iii is ridiculously pricey and i will NEVER buy it :)
Any advice; used canon tc 1.4x ii is like 250-300 which is still pricey but manageable if it's my best bet; anyone tried a TC with 6D? please advice me. If I pay 300 or so I can always buy the 70-300 IS; and some third party TC will trick the camera and make it autofocus at aperture F8 so that would be a thought.
I know dedicated high grade or high zoom prime is a thought; but I don't want to spend like on the 300 prime or 400 or 100-400 at this stage.

happy shooting

But I prefer NOT to buy another lens; just a TC. Canon or 3rd party? any thoughts esp on a new untested body 6D

The Canon Extender 1.4× II has worked very well with the 70~200/4L IS on every EOS body on which I have used it, including FF bodies (but I have not actually used the 6D, although there is no reason to doubt compatibility). If you want to keep costs down, look for the original version, which is optically identical, and can be found s/h. You might still find a new II on the shelf somewhere, and it can certainly be found s/h.

I have no idea with the 6D, but with the 7D and the 5D MkIII, the Canon 1.4X TC will slow down the AF, but not as bad as some (most?) third-party TCs. Your 70-200mm is not a Series II, which are optimized to work best with the Series III TCs. I use a Series II TC with my 70-200mm f/4L IS with only minimal slowing, so I'd advise finding a used EF 1.4X TC-II, unless you can try the Kenko with your camera and lens, or find a review from someone that's already taken the plunge. Lots of Kenko TCs work with lots of Canon bodies and lenses, but it's not universal and you can lose some functionality and speed of AF.

Personally, I would think putting anything other than the Canon 1.4x between that camera and that lens would be doing severe injustice to both the camera and the lens.

The Canon 1.4xIII extender can be had for under $400, if you a) shop around a bit and b) don't mind buying used or refurbished.

For wildlife, 400mm is about the entry level focal length. Serious wildlife photographers go for the "big whites": 400 f/2.8, 500 f/4, 600 f/4 and 800 f/5.6.The 300 f/2.8 is also a credible option with the Canon extenders.

If wildlife photography is what you really want to get into, I'd suggest forgetting about the extender, and getting the 100-400 to start off with, or - if you don't mind losing IS - the 400 f/5.6. If wildlife is just a casual or occasional subject, then the extender is a good start.

I've used an older Sigma 1.4x converter on my 5D3 and it worked fine. I use it with a Sigma 150/2.8 macro, sometimes with a Kenko extension tube in the middle. The image quality is fine and everything functioned, even with the extension tube autofocus worked pretty well. That might be an option if the Kenko 1.4x has compatibility problems.

Yeh thanks guys for suggestions; so far ex ii wins; I will look at the sigma too

Jay DeSimone , Dec 13, 2012; 11:56 a.m.

The Sigma 1.4x works with my 70-200 f/4 on my 7D (although I don't normally use it with this lens). I don't know why it wouldn't work on a 6D as well. I only have Kenko extension tubes for macro work, and they also work fine.

Ed Avis , Dec 13, 2012; 12:26 p.m.

I believe the older Canon 1.4x mark I is optically identical to the mark II. The difference is weather sealing. So you may go for the older 1.4x if you see it at a good price.

Jamie Robertson , Dec 13, 2012; 01:00 p.m.

Why not get yourself one of the 1.6x extenders instead? Like the 60D for example. Can't see the point in FF users buying the Mk3 1.4x extenders when a decent 1.6x DSLR costs little more.
