Which 1.4x TC

I've read several threads on TCs and I just want comfirmation on my choice.

I plan on buying some combination of the following lenses for use on my 30D: 70-200 f2.8 IS, 70-200 f4 IS, 100-400 IS, or the 400 f5.6.

I plan on buying the Canon 1.4x TC instead of the Kenko Pro 1.4 TC. Based on what I've read, the Canon might be a slightly better overall performer. As I understand it, I'd have to tape either TC for use on the 100-400 or the 400. I don't mind paying the premium for the Canon if it's better than the Kenko.

Your comments are welcome.

I have the old Canon 1.4TC and the Kenko TC, and I prefer the Kenko... I'll elaboriate later on with images.

Looking forward to the pics.

But can anybody explain in the meantime? Shouldn't Canons TC be better?

Just got myself a 70-200 L 2.8 IS and I am wondering first of all if I should buy a 1.4x or a 2.0x (for airshows etc.) and second if it should be Canon or Kenko.

The percentages of clean shots become iffy with the 2x, which of course would be desireable by everyone if it was as good as the 1.4x. The reason why everyone buys the 1.4x is because its one stop more light available so you get some decent autofocus.

My experience with both is yes you can use them both but the 1.4x is much more consistent. I used the 2x today on my 70-400f4 IS and got fairly good focus. Its such a sharp lens the degrading isn't too bad with the 2x. You do lose a little detail. But acceptible in good light.

The 1.4x doesn't give you much more reach it becomes a 280mm. So it's not long enough for birding. But the quality and percentages is good.

On the 2 400's you mentioned, the tele's might work in good light. All of them are pretty decent if you manual focus and use a tripod. You can stack them but at that point a tripod and manual focus is needed.

I was quite happy with the ability to autofocus yesterday. A better consistent focus than with my 300f4. [so I use the 1.4x on the 300f4, that giving me 420mm]
The 70-200:





you do lose a little detail as i said

Canon won't let you focus. Even if you tape pins, the AF is slower from what I have heard.

I just put on order to buy one for my new 500mm f4 IS.

The should be, but appears not to be . TCs tend to make the images rather flat & some contrast enhancement improves the images.

Two shots below were taken with Canon 100-400 plus cheap Kenko 2x TC. Handheld, manual focus, resized, contrast enhanced and USMed.
