Sigma 50 1.4 815 grams official weight. My 24-105 Sigma is heavy as well but worth every gram.
We're getting to the point that equipment size and weight is increasing so much that practicality is at stake. More bulk means less space remains in the bag for other lenses. It's good to limit the stuff you carry but can be good to have a little extra space for contingency lenses. This is why I keep the old 35 f/2 and 50 f/1.8 which sacrifice a little in image quality but are very compact which is great especially for travel. note that I always limit myself to the minimum I think I will need, and my lowepro minitrekker AW is the measure for the maximum volume I want to carry.
