Hi Folks,

I have a small question. I have a Canon 7D and need a new telelens with it.

Most of my photography is done at airshows, my old lens, a 70-300mm, was used at 300 for about 90 percent of the time. Fast action, but also at time, slow passes.

Lenses in consideration:

Canon 300mm F4 IS L with/without a 1.4TC

Canon 400mm F5.6 L

Sigma 120-300mm F2.8 EX OS DG

Sigma 300mm F2.8 EX

Anyone who has had one or more of these lenses? Curious to your experience with them.


I have the Sigma 120-300 f/2.8 EX non-OS version. It is a very heavy lens, focus is not as fast as my other Sigma zoom lenses. Which are the Sigma 70-200 f/2.8 HSM non-OS, and the Sigma 150-500 OS. Sigma harps on the fast focus speed of the 120-300 f/2.8 OS, so I'm guessing they've corrected that.

The ability to calibrate the Sigma 120-300 f/2.8 OS at home is a big plus, even considering that your 7D has MFA.

I really like my Sigma 150-500 OS, it's fairly lightweight. The 500mm reach is great, and it focuses fast and accurate. I did a lot of online comparisons with it and the Canon 100-400 L and it was the winner in my opinion. And at around $1000 it is priced right.

I use Flickr group photo pools a lot when comparing lenses. I figure that gives me an idea how the lens performs in the real world in the hands of the masses, not just the factory pros or in studio shots.
