hi guys... can check whether anyone uses this lens with a TC on a 5D mkiii??..
can it still AF??..

thanks...

It certainly will, no doubt. Even with a 2x TC it will be f/5.6 so it will retain AF. Although now that I think about, doesn't the 5DIII have f/4 or faster AF points??

So yeah, good question :)

It has, but so do most of the bodies have. For example my 450D has a crosstype AF point in the middle. In one direction it is a f/2.8 point and in the other direction an f/5.6 point.

Of course it will work, else you wouldn't be able to use AF on for example an 70-300L f/4-5.6 at 300mm ;) So the 120-300 will AF on any recent Canon body with the 2x teleconverter (also with the 1.4 of course). If you want to stack the teleconverters, it will only AF with the 1D series of bodies (but not the new 1Dx) and only using a few points (or even only the center af point).

Yes, I agree. By using CS5 my image quality went up considerably, due to the new ACR and the reduce noise tool.

Great shots as usual! The one with Hummingbird shot with stacked 2x and 1.4x is fairly good and usable even though I can see some degradations. Yes I agree with you that the new ACR is considerably better in NR. I set mine about 20 to 30% for the higher ISO images, and the noise is fairly non-existent compare to the ACR (forgot which version) on my CS4. It's so good that I had to retouch some of my older photos.

Bird of different feather here. Sweet lens... here's one at 600mm, doubled with Kenko converter, through heat haze and all.

I collected my copy this evening. It's certainly a big ol' lump of glass!
I was supprised that the AF speed is a little slower than I anticipted. I'm sure it's fast enough for most stuff, but i have been a bit spoilt by the AF speed of the Canon 70-200 f2.8 L IS II and 400mm f5.6 L!
Loving the whole objective lens looks like a small dinner plate look!

I was fortunate enough to use this lens this past week to shoot some lacrosse. The lens was very sharp and was nice to handhold. The only issue is that the AF was only OK and there were a lot of missed shots. The lens was nice overall though.

In some birding practice locally I discovered what is probably a weakness for the lens - shots at midrange distance (i.e. 20 meters or so) with small details in the distance.

The polygonal blur shapes in a water background are really distracting, unfortunately. It's a shame because if I open up to f/5.6 (i.e., 2X TC on) I'll lose a bit of sharpness, and it'll still be distracting (just not so much).

Still, works brilliantly for anything close-up. I'll have to post my best ones sometime. The 7D really makes all the difference over the old T1i with its too-small viewfinder and slow, inaccurate AF.
