I am looking to GET LONG, and spend about $ 1000 doing so. I intend to use the lens for mostly wildlife shots, then secondarily sports (outdoor soccer), then lastly just to mess around in concerts from far away, or do closeups of faces.
Here's what I value in terms of importance in the lens (I have a 7D body, and a 1.4x T-con if that makes a difference)
1. AF speed / Accuracy
2. Sharpness
3. Other IQ traits (contrast, color rendition, CA, etc)
4. Reach (more than 400?)
5. IS capabilities
6. Versitility (Zoom vs prime)
As far as I can tell, my options in this price range (if I go used) are
1. Canon 400 5.6
2. Canon 300 f4 IS (with the T-con I have)
3. Canon 100-400 IS
5. Biga 50-500
6. Bigma OS 150-500
Based on the reading I have done, it would seem the Canon 400 5.6 would be my best bet considering what I value in a lens. Closely followed would be the 100-400 or the 150-500.
If anyone can give me some further insight, it would be very helpful!


He and I have traded comments various times on this forum, sometimes agreeing, sometimes not. Certainly, honest men can disagree.
