Looks very nice.
Charlie, I see you have the canon L one as well? How does feel compared? Not sharpness, but just in general. AF, zooming (I see the zoom ring is quite slim compared to the canon)?
The lens feels great, kinda like the 24-105 and build quality looks like that level as well. The zoom and focus rings are quite stiff in comparison to the L, but both smooth, so that takes some getting use to. The throw is quite short, like the 50 1.8.
Just a minor learning curve. Due to being slight shorter and not as heavy as the brick, the weight/handling issue is noticeable compared to the L.
