one of the reasons i went full frame was to not have as many lenses. however i too have way more stuff if i included other stuff like....light stands, umbrellas, my alienbee + a lot of nick nacks and cords....
contemplating ordering the Sigma 35mm f1.4 though.
their new ART series is really nice. i had a Sigma back when i had my 20D and it was a great lens, definitely won't fall apart. I've seen some of their 50mm's need adjustment....but never fall apart. Sigma seems to be really turning around and providing some much needed competition in this arena.
Sigma's 35mm blows away the 35L and the Zeiss optically. Check it out on DxO Mark and any other review.
