comment:The view is just amazing on full frame. The sharpness of this lense is ok. I am kind of spoiled by the CZ 24-70's sharpness. The corners on this lense get very good once stopped down past F8.

Build quality is good, the typical Sigma EX DG build. I don't really like the feel of it though. The lense is light which is a plus but I would have liked a bit better build.

Also, this might only apply to my used copy but the focal length zoom is stiffer in the 12 mm and 24 mm end and smoother in the middle.

My biggest gripe for this lense is the ability for filters. I don't see any practical way to attach a ND filter to this lense. I might be able to hold the filter infront but I don't think there is a way to attach it for use at 12 mm.

I am very with this lense, for an ultrawide (12 mm!!!), the optics of this lense is just phenomenal. Sigma did a goos job on this lense!
