How is IQ after putting the Canon 1.4x extender on the 135mmL (on a 5D)? Does one lose much sharpness? Are there other things I should be aware of (for example: does AF still work, what becomes the minimum aperture)?
I just got a 1.4X and took my first pictures last weekend with the 135L and 1.4X on my 5D. I was very impressed with the results. AF works great and still very quick, minimum apeture was f/2.8, and the results were very sharp with good color and contrast.
The IQ of the 135 with the 1.4 is hardly noticeable at all on a 5D even under intense pixel peeping. This is a great combination and how I get a ~200mm f/2.8 indoors.
I had always read that IQ isn't affected and that many people skip over the Canon 200mm f2.8L prime because of this. I finally got around to using the combo last week on my 20D and although I didn't do extensive testing, I was pretty pleased with the results. The combo makes for a nice close focusing set-up too. Here are some of my samples:
Mind you, these are stopped down, but I didn't see any significant IQ loss wide open @ f2.8 either.
WOW, a 135mmL and 200mL in one excellent package. Off to the shop again... BTW defresh, those "macro" shots look superb! Did you do some cropping on these shots, or are these FF?

Thanks Daan. And yes, I did do some minor cropping to these shots.
As everyone has said, you won't notice any difference except for the focal length and aperture. The backgrounds stay silky smooth and the sharpness doesn't change a bit.
Definately a superb combo on the 5D. Perhaps consider the Kenko 1.4 DG instead of the Canon as the Kenko will fit more Canon lenses.
And it color matches the 135L nicely, but then you might have some long white boys...

Oh, what about 3 1.4x TC's or a 2x+1.4x? That'd be a 378 f/5.6. Perhaps that vs. the 400 f/5.6? This combo is probably pushing it...
Hah, that's funny, the day I shot Football with Travis, I had the 2x and the 1.4x stacked on the 135 for storage, but I didn't shoot anything with it. I have used the 2x and the 135 and the quality was pretty good, but I can't judge as the jpeg files were compressed at 10 out of 12, so it's hard to tell what the exact quality was
oke:
