I have a Canon 35/2.0 prime lens that I really like, but it's not wide enough for my Canon XTi. So I bought this lens along with a Sigma 18-50/f2.8 EX Macro for the holidays, thinking the Sigma would be used for more flexibility and the 24mm lens for a very lightweight touring lens. although my 24/2.8 wasn't nearly as sharp as my 35/2.0. Maybe it's just my copy of the lens, I don't know. But the Sigma was just as sharp as the 24mm. So I returned 24mm and will be leaving Sigma. With a fixed zoom you lose zoom, so it's better to be a) sharper and b) brighter (large aperture). Since it was the same sharpness as Sigma, and not brighter, it's going down. I was thinking of selling my 35/2 but will keep it for now as it is both very sharp and has an f/2.0 aperture. my needs, I won't try again.
