Says the guy who complains like

The bigger question mark may be whether you are bold enough to carry such a brick. At more than 1.1kg, it's not for the weak. While we surely congratulate Sigma for releasing high-quality lenses into the market, we aren't sure that super-sizing everything for gaining quality is always desirable. It's good for getting fairly high ratings but it reduces the fun factor to some degree - and for most of us, fun is what all this is about.

Apparently it has to be the right brand coming up with bricks...   This one weighs 1.4 kg and comes without AF.
