Tangent Warning:
Anyone got experience with the Sigma 120-300 f2.8? I'm not the biggest fan of third party lense, but on paper it sounds like it fills a gap for me nicely. I will probably take my own advice and rent one to test drive first. But any first hand experiences are appreciated. I'm mostly concerned about IQ, Speed and durability. CameraLandTamronPhotAdv do you think Doug would make me a deal on a Canon model?
