"If you want great images from f/1.2 to f/2.8, the 50L is the only lens that will do it. But narrower, there are actually better lenses."
This is simply not true. For the money, at f/1.4 the 50mm Sigma out performs the Canon 50L. ...and think of all of the money you have ...to put toward another lens!
i agree with the sigma 50 1.4,
i have the canon 50 1.8, loved it and bought the 50L 1.2 and the love was great but quickly fades away after the sigma 1.4 went on sale.
i got better keepers with the sigma than the 50L - yes, the Sigma cant match the beauty of the bokeh of the 50L when the AF is spot on, otherwise, for the price, the Sigma is a great lens.
I sold my 50L and kept my Sigma. // just like with anything in life, things could change //
