Hey mate,


I'm a lucky Sigma 50mm 1.4 owner and I'm very happy with it. You must notice the "lucky" part in my sentence, because these lenses seem to have focus-issues. Pretty much every one of them 50mm Sigma lenses if you may believe the stories.


In short words: the Sigma can be a lot better than the Canon. Mine had just a little front-focussing which was solvable by micro-adjustment. Now it's usable sharp at f1.4 (better than the canon) and it gives me amazing sharp results from f2 and on.


My advice: if you're buying from a local dealer where you can easily try it out and have the opportunity to return it if it turns out to be a real disaster, buy the Sigma. Oh of course if you have micro-adjustment, that would be great too. Else you better go to the safe side and buy the Canon which is softer wide open, but doesn't have(or less) focus-issues.


An even safer bet would be the canon 85mm 1.8, but it would be a different focal length...
