Sigma 100-400mm Lens..

[Alysia]

I was looking at getting a Sigma 100-400mm lens for my canon 450D.
I want to use it for wildlife, but I was told not to buy one, because it lacks quality.

Does anyone own, or has owned this lens that you could give some advice on the lens.

Thanks

You are talking about the 120-400 ??

Who told you it lacks quality ? in what way/area ?
A quick search has found these threads, some good and bad in each

The Canon 100-400 L has a very good rep (ask Richard hall).

Sigma 150-500 ?
