Alright, I've decided against the Sigma and decided to get the Canon 70-200mm f2.8L non IS. I plan on getting a 1.4x TC for occassional use and have heard that Tamron and Kenko's TC are compatible except for some softness around the edge, which won't be a big deal on a smaller sensor of the dSLR. Has anyone tried either one of these?

I have the Tamron-F 1.4x and it is pretty darn good for $80 or so, at least on a 1.6x crop body.

Tom,
Which lens are you using it for? Is the focus speed slower with the TC?

I also have the Tamron (not the Pro) 1.4x. I have not used it extensively with the 70-200, but when I have, I've been fairly well satisfied with the results. I do recall seeing a comparison of the Tamron, Kenko (I think it was), and Canon in an old thread over at DPReview, and there was a moderate advantage with the Canon in contrast and sharpness both.

| Quistion. If you are going to buy the higher cost Canon Glass, Which I think is the best way to go, why would you compromise and not get the Canon 1.4x? |

I have used the Tamron-F with a fairly wide variety of lenses.
EF 200mm f/2.8L II
EF 70-200mm f/2.8L IS
EF 300mm f/4L IS
EF 400mm f/5.6L
EF 100-400mm f/4.5-5.6L IS
EF 400mm f/4 DO IS
It seems to work well on all of them. The AF isn̢۪t quite is fast and accurate as it is with the lens alone but it is only a very small step down. I have tried using the Canon 1.4x with taped contacts and it is not nearly as fast on lenses like the 100-400 and the 400 f/5.6 that weren̢۪t really designed to AF on a 20D.

The Canon converters are great, for the lenses that they fit. They only fit the longer L glass, however. The Tamron is more flexible in that it will mechanically fit almost any EOS-fit lens, Canon or otherwise.
