Sigma loses big in a showdown between the Tamron and Sigma 70-200 f/2.8 on a Canon EOS 7D

Summary: Under sports shooting conditions, an image stabilizer seems unnecessary and very expensive. Thus the selections immediately narrow to Canon EF 70-200mm f/2.8L USM Macro, Sigma 70-200mm f/2.8 DG HSM II Macro, Tamron AF 70-200mm f/2.8 Di LD IF Macro, and Tokina AT-X 828 AF Pro 80-200mm f/2.8 SD. Tokina is no longer in production and no useful review can be found thus given up.
Too much chromatic aberation and not very sharp wide open

Summary: I bought this lens because I really wanted an F2.8 and couldn't afford the Canon. It seemed very nicely built, focused quickly and accurately, and, while not cheap, a good value. Unfortunately it had really quite bad chromatic aberration at the longer focal lengths (which is where I mostly used it). Bad enough that with a subject against a bright or dark background it looked like someone had outlined my subject in red magic marker.
Summary: I made the mistake of trying to save money when I switched from Nikon to Canon. I bought this and Sigma's 17-35 f/2.8-4 DG EX while building my new system. I ended up selling my Sigma lenses to buy a Canon 17-40 f/4 L and a Canon 70-200 f/2.8 L lens. Sigma lenses are very tempting because they cost much less then Canon or Nikon lenses. Unfortunately they are cheaper for a reason.
