Canon 1.4

You will get conflicting opinions on brand; as with all glass, the best solution for you is what you can afford which produces an acceptable result.

i figured since you are so set on the Canon being superior that you must have used them both and found the Kenko to be lacking.

Well, I wish you would show me where I said Canon was superior and/or Kenko was lacking. I suppose you can read anything you want into what I say but that doesn't make it so.

You stated, "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."

Seems like Snir's "reading" is fair to me.

this line implies that Kenko did sacrifice IQ in order for the TC to fit more lenses.

I used my Canon 1.4x II on the 100-400 with lackluster results. Bleh.

I put a Tamron on my Canon body and then put a Sigma 70-200 or a 24-70 or a 30mm1.4 on it. Sometimes I get all funky and put the 100-400 on the TC!

That sorta stuff is outlawed in 42 states.

I have never seen anywhere that someone claimed the Kenko TC is superior to Canon's TC. I have seen where Kenko users have said the Kenko was soft around the edges. It really doesn't matter to me, because there is just not enough difference in cost to even investgate. For what it costs ($280) it's worth, to me, going with a TC made by the camera/lens manufacture that, unlike third party products, is designed from the get go (not reversed engineered) for the camera/lens pairing. If there were $400 difference then I would investagate different products. So, in this case, yes, "I'd be damned if I would put anything but a Canon TC between my Canon camera and Canon lens".

For the OP...I have used the Tamron SP Pro 1.4x TC on my 100-400 with decent results. I would say that they are on par with the results from the Canon TC. I have both...the Tamron because it is smaller and fits more lenses and the Canon for the weather sealing when used on my 1 Series bodies.

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.

What Camera?
Do you want to keep AF?

On a 1Series the sensible choice is the Canon. You will retain full AF and weather sealing with any weather sealed lenses you might use it on later.

On a 30D/20D or other, if you want to try and maintain AF, the Canon won't.
The Kenko might, and often does, but it isn't guaranteed to offer full AF functionality either.

I guess we assumed that the statement you made about being damned to use anything but the Canon (twice now) was actually based on some actual experience or knowledge of those options that would in fact cause you to be damned.

that is pretty much spot on. if you have a lens and body that is weather sealed, the Canon is the obvious choice. however, if you are using a 30D and a non sealed lens, all you are paying for is the name and the white color because the optics are very much the same.

I have the canon 1.4xII and the kenko pro 300 2x. I love my kenko pro...mainly because of the unlimited use I have with it. And it is extremely fast w/AF on my 200 f2.8 so I'd say that the AF's are comparable on both units. The optics are comparable as well, (though the 2x is obviously a bit softer but NOT much). If I could do it all over again, I would have bought the kenko pro 300 1.4x because I hate not being able to use my tc on all my lenses....
