I know this is out of the price range, but the new Sigma 120-300 f2.8 OS, sounds like it is made for this type of shooting. I have only seen a few reports on line and everyone is talking it up.
Rich have you heard anything about this lens yet?

Based on your pictures my first choice would be a 70-200mm f/2.8, but the135mm would not be far behind. What noise reduction software do you have? If you are using DDP then you could gain about 2/3 to 1 stop with a good software like DxO, CS5 ext. A 70-200mm f/2.8 on a FF is equivalant to a f/1.8 lens on a 1.6 crop camera, but the AF is not as good as your 7D so your only reall option is a 70-200mm (or 200mm f/2.0) and 1Ds III. ;-)

Wow, I really appreciate you all taking your time. And as I was expecting/hoping you have helped me to narrow down my options to 2, the 100 mm options don
Let us know how it goes! And if you end up with the 135, tell me so I can be green with envy.
It also applies for noise. Asuming you have the same sensor technology, the thinner the DOF the better the noise regardless of sensor size. For example, if you look at Bryan

Take the statement, "<span>Asuming you have the same sensor technology, the thinner the DOF the better the noise regardless of sensor size," let's assume you have exactly the same sensor - are you saying that a shot at f/2 would have less noise than a shot at f/5.6?
In your example, you're comparing different sized sensors - and you seem to be saying that if one shoots with an aperture 1.33 stops faster on the 7D, that the noise will be equal to that of a 5DII. That's certainly not the case.
Can you provide some clairty, John?
Thanks!
