I've had this lens for about 8 months or so - it's perfect for street photography and indoor event photos.
Yes, there's really bad CA until you stop it down a bit, but even at its worst you only need to click a check box in Lightroom to eliminate it.
Contrast and bokeh are good, for such a wide lens. The thing is, i dont think there's another prime in this focal length with an aperture this large, especially for the price point! Some of the ultra-nice wide primes (like Zeiss) are in a whole different class when it comes to sharpness and contrast, but they're at least 4 times the cost.
I initially bought the lens to get a ~50mm equivalent on my T2i, and it worked really nicely for that. Are you on crop or FF?
Here's a shot i took with it at f/2.2 . Keep in mind, this lens flares like crazy when shooting into the sun. Unless i'm trying purposely to take a landscape style image, it doesn't bother me. Probably not the best for long exposure at night (with bright lights in the scene, at least).
There's nothing done in lightroom on this image aside from default RAW conversion, crop, and removal of CA
