3 lenses: Sigma 17-35 Canon 28-135 IS USM Canon 100-400 IS USM L Also I tested how they behave with and without Image stabilizer. You can see the difference is awesome! It's actually the reason I sold my Sigma 50-500 and bought the Canon 100-400L with IS. Hope this vid. is any use to you people out there!
