According to the Taiwanese site, it says: - The Tokina feels compact in size, similar to the Nikkor in size, where the Sigma was designed for both 35mm and D-SLR and therefore is larger in size. - The Tokina gives a feeling of solidness (i.e. good build quality), feels better than the Nikkor, zoom ring feels a bit tight, the push/pull auto/manual focusing switching is not quite as good as FTM. - Nikkor AF speed is much faster, Sigma has the closest focusing distance of 28 cm, and is the only 12-24 mm zoom lens that can be used with 35mm camera, Tokina has the largest lotus flower like lens shade. - Scoring comparison: - handling : Nikkor > Sigma > Tokina - corner darkness (vigenetting): Nikkor > Tokina > Sigma ( > means better, not greater) - image quality: Nikkor = Tokina > Sigma (again > meaning better) - barrel distortion: Sigma > Nikkor = Tokina ( > means better) - value (bang for the buck): Sigma = Tokina > Nikkor ( > means better in this context) Some further discussion by a 20D user indicated that maximum aperture performance is pretty good, very sharp, but has some purple fringing, poor flare characteristic, but is better than the EF18-55.
