I'm considering these to use with a 5D (or maybe 20D or good old film body) - considering I also have the following lenses, Sigma 70-200, Canon 100-400, and Canon 85 1.8 - which are best, price being somewhat of a consideration ?
OK - never mind - Canon is fine, better IQ according to BobAtkins - though it doesnt work with Sigma - not a problem here - and the price diff is negligible..$100 or so - don't know if it would work with the 85 1.8 .. will find out at B&H I guess ;-)

Kenkos have the best glass inside...

It does NOT work with the 85 mm f/1.8 lens. I believe the Kenko does work with it. Not a problem for me (with the Canon) as I use other lenses instead of considering the 1.4X with the 85.

Ah - thanks for the reminder about the excellent review and practical conclusions - so yep, should get the Canon 1.4X for my L long zoom 100-400 (and future 300 :_)
Now probably not worth getting the 1.4 Tamron/ Kenko considering I have the Sigma 70-200 that would cover that 120mm from my 85 1.8 - though I would bet the 85 + 1.4 combo would be better..

I've used all three. I can see absolutely no difference between the Kenko 1.4X 300 Pro and the much more expensive Canon. I sold the others and kept the Kenko. I use it primarily on my 70-200mm f/4 L and my 100-400mm L. In good light, with pins taped, it autofocuses reasonably well with the 100-400 even @ 400mm. When traveling, I even use it with my my 24-105 to get a bit of extra reach.
Hope this helps.
