I have a 100-400mm L lens and am considering getting a 1.4 or 2 x teleconverter to go with it. Any suggestions? Photos you have taken with either of these combinations? Thanks for the help! Matt

Usually the 2X doesn't work very well with tele zooms. The picture gets degraded too much. I would think you'd have some good results with the 1.4.

Definitely only 1.4, and even that may be borderline with that lens.

I have gotten fine results with the 1,4x extender. But would definately not try a 2x on this lens.

is there quite a noticable image degration? Anyone have sample pics with and without the tc? Thanks

Also remember, on a 1 series body you will only have AF with 1,4x extender. with the 2x extender you will have no AF at all on any body.

Also have a look in this thread for lots and lots of information about extenders: http://photography-on-the.net/forum/showthread.php?t=41922

The 1.4 will work well with the 100-400L. I have the Kenko 1.4 Teleplus Pro 300DG...had to resort to the tape trick to enable AF. This shot was taken at dusk with the 100-400L and the 1.4 on a 5D2 (560mm):

While others have had good luck with a teleconverter, my suggest saving your money and just zoom and crop in PP.

I've had good luck with both teleconverters from Canon, I just got a new 100-400 and have only played around for a few minutes with them but think it's worth persuing. The not being able to use AF with the 2x is no problem on my MKIII because it is so easy to manually grab focus with a lens that long.

Cropping to a decent shot is less successful than using a converter, which itself is less successful than having the right focal length prime lens.

But I cannot justify the cost of a 600mm prime, so I use a Kenko PRO 300 DG on my 100-400 and while I know the 600 would be better I am reasonably pleased with the results. I have tried cropping to the same result and let me tell you the quality was dreadful, it throws too much resolution away.

I've not tried the 100-400 + 1.4x but for a few images, here are a couple samples

with a 40D (manually focused with liveview)

with a 1D Mark III (I think also manually focused with liveview)

With my 500D I lose autofocus when 100-400L has a converter mounted. The 1.4x converter will degrade the image. Better to use 100-400 without converter, and crop as required. You will get better IQ, and still retain autofocus, plus extra f stop.
That's my experience for what it's worth.

Pixels,

That's probably because you are using a "reporting" converter, that's one with 11 pins. The camera has to fooled by taping over three of the converter pins, then it will all work.

Your 5D is probably like my Eos-3, works with it even without the taping. My 30D is like your 500D but trust me it can work. The sticky shows how to tape the pins, all I've used is a tiny piece of clear Sellotape.

I've gotten good results with the 1.4x converter with the 100-400mm, but autofocus is restricted to the center focus point on the 1D Mark III. I haven't tried the 2x since I would lose autofocus.

The 1.4x converter works fairly well with the 100-400L, however, especially on a small frame camera, a solid base and efforts to reduce vibration (such as use of mirror lockup and a release cable) will pay dividends. As with any long lens combination, camera/lens shake is a prime consideration.

I have been quite happy with the AF when taping the contacts.

I have used the Kenko 1.4x, the 2x and both stacked with great results.

You might find this teleconverter archive interesting as there are many 100-400 samples.

For example, these two with the 2x...

From my experience the Canon 1.4 TC does well with the 100-400. It auto focuses quickly and accurately, and IMHO there’s not much loss of IQ. As others have said you will be limited to the center auto focus point on one series cameras and you won’t get auto focus at all on non-one series cameras unless you do the tape thing. Here are a few examples at the middle and extreme focal lengths with a 1DsIII:

Hope this helps, and good luck with your purchase.

the 2x works semi well with the 70-200, not worth the IQ loss on the 100-400, but I use it like a spotting scope attachment when I am sitting and waiting for critters to appear. If I do see a critter I want to capture, the 2x comes off and I either hope for a closer shot or start stalking, wich is usually unsuccessful and I should have settled for the 2x shot. Oh well.
I have it, I use it, it is what it is: a poor replacement for a much more expensive alternative.

Next few days are a good time to try it - crescent Moon in the West early evening.

Team Speed, I am planning to use kenko dg 2x tc for 100-400mm.
Is the kenko dg 2x will perfom better with 100-400 if I use canon 7d?
Cause I see that your pic were taken using mk3. I mean for performances are the af function and the image quality.

Do you mind helping me to give some shot sample?

Thanks

You will still have to focus manually, also the 7D gives you more resolution, but it is hard to say if the shots are better.

Here are a couple of 7D with 2x shot I posted in the 7D photo archive. I don't think I have had too many other 7D w/100-400 w/TC shots right now.

team speed thanks for the image result. the image looks fine for me.

Have you ever compare between kenko 2x tc and canon 2x tc if we use 100-400mm lens (with no full frame body) ?

do you have any image using canon 2x tc + 100-400mm lens ?

Never used the Canon, based on reports I always have used kenko due to the situation where it seems to be less finicky with lenses than Canon.

These were taken just shortly after getting the lens. They are hand held from the top of a parking garage. They seem acceptable. The second image shows some depth of field.
