I bought a used Sigma 120-300/2.8 (the old version) a couple of months ago to try to get some better "under the lights" shots when my favorite team (Klein Oak) made the playoffs. It certainly gave me better shots than I could have gotten with other lenses I have.
Now I'm uncertain whether to keep it, buy the new OS version or get the new Canon 300/2.8 IS. I do like the flexibility of the zoom. Any thoughts, especially from those with a Canon 300/2.8?
These are with a Canon 1D MkIV - Klein Oak vs. Dallas Jesuit at Baylor Ballpark
