That's odd... mine was lighning fast. More to do with the body you used it with perhaps?

Using a 1D and its definitely a tab slower on AI Servo. It's still fast but I did notice a difference taking some jet ski pictures in the summer. I love it being black too. Mind you I was using a CPol when I noticed this slight hesitation so it might have caused the slightly slower focus, so it did hunt a bit more with the lower light.. Its a beautiful lens and quality in my opinion doesn't get any better.

Ahhh... yeah, the CPL would explain it. That would drop it to f/8 for focusing which is not ideal. You'll notice the same thing adding TCs.

AI Servo AF sampling rate is varied by the camera depending on the amount of light hitting the AF sensors. If you've just chopped the best part of two stops of light out by using a polariser it is going to slow to a crawl.

Yeah the servo worked light years faster once I removed the filter, didn't realize how much it stopped it down.

Awesome pics Guys! I've just managed to pick one of these up on ebay for £295, used but seeing as there £750 new I couldn't let it go for that price. It originally didn't sell due to the reserve but the guy second chanced it so I snapped it up, your pics really helped alot. Im really hoping I've made the right choice :D

This lens is awesome. I used it on my 30D and loved it...now I use it on my 5D and love it even more! HSM is excellent though I wish sometimes there was a focus limiter.

The matte black crinkle finish is peeling off of mines. Has anybody else had this happen?

It's normal with all EX lenses. Lens coat (TM) is recommendable, there is even one in black color which mimics Sigma's original color. :cool:
Lovely pictures, by the way, the 2nd one is awesome.
