I'm looking at the Sigma and Canon 70-300 mm lens for around $200. Then there is the $550 option for the same focal lengths/aperatures.
The $550 has Image Stabilizer ... and I'm guessing the expensive one is of better quality. Question is, how much better quality? Is it noticeable? Is it worth $350 more?
