Looking at your comments Joe I did a Google and the first review I saw said the following

Unfortunately, I consider the Sigma 20mm f/1.8 EX DG Lens to be unusable at f/1.8 unless you are looking for a soft-focus effect. This lens is one of the softest I've seen wide open. Realistically, this will be an f/2.8 lens to most people as the center does not become decently sharp until this aperture. But wait - there goes the Sigma's uniqueness advantage for now there is a direct Canon counterpart, the Canon EF 20mm f/2.8 USM Lens that costs about the same price.
