I've decided to make the plunge to buy a 1.4 teleconverter to use with my 100-400IS.

I know this isn't optimal but for the few situations I might use it in, I think it will work.

Which one would you recommend: Canon, Tamron, Sigma, Kenco(sp?). I'm not sure who makes one, other than Canon, that will work with this lens.

Either the Tamron or the Kenko. I have a Tamron 1.4 that works on the 100-400.

I'd go with the Canon - I want my optics matched.

Kenko Pro (or the identical Tamron SP): equal optics to the Canon, but much less restrictive since it takes any EF lens. Smaller and cheaper too. Almost a no-brainer.

If the quality is there, that sounds like the best deal. One of the complaints many have about the Canon TC is the limited number of lenses it can be used with.

I went with the Kenko 1.4x Pro myself after hearing all the good review. I figure I give it a try.

i have been using the Kenko pro 300 DG for the past 6 months and i LOVE it. it has great optics and the price is good. i am not sure it is better than the Canon but i can tell you that i get great results for mine. i am thinking of selling it and getting the Canon though because i want the weather seals.

Thats also the only reason I would go with the Canon version, is for the Weather sealing...

I see a lot of reviews and the Kenko 1.4x is a good buy. I dont see much on the 2x and I think there is also a 3x, but I dont know if thats even worth considing.

I am using Canon 1.4x and i can't comment on another TC's.
I heard that Canon lost AF so is that another reason not considering canon as well?
I will never use 3rd party even high quality, canon with canon, sigma with sigma, canon with canon, don't get me wrong please.

I prefer Kenko 1.4 Teleplus Pro 300 DG. Haven't used it with 100-400 IS, but with 70-300/4-5.6 IS USM is very useful. That converter is "transparent", in EXIF we see all as if without of converter. The lens try to autofocus; if the light is not enough, we have MF with the sharpness confirmation, and IS works.

One of the complaints many have about the Canon TC is the limited number of lenses it can be used with.

And this could be due to the fact that Canon did not have to sacrifice IQ when designing this lens as much as it would had to if it fit a larger number of lenses. If you only plan to use it with the 100-400L the point that third party TCs fit more lenses is mute anyway. I'd be damned if I would put anything but a Canon TC between my Canon camera and Canon lens. I can understand if someone is limited budget wise but for many the difference in cost is small.

I have the canon 1.4 TC and use it with both my 70-200L and 100-400L. AF is lost with the 100-400, but its not very hard to focus if you have a still subject.
