10 out of 10 points and recommendedSharpness where it counts, light weight (this is relative), focusing accuracy on my copy, and great bokeh. If you get a good copy you will love it.None worth complaining about, it vignettes (correctable and typical for this type of lens), has some CAs (shoot RAW if you care about it), and people complain about corner sharpness, but if you are trying to get corner sharpness at f/1.4 your probably jus
This is a great lens, lets get that out there. Someone mentioned that it is a photographer's lens, and I agree wholeheartedly. This lens is PERFECT for indoor shooting, people shots, and as a general walk around lens. The shallow depth of field for a normal lens on a DX body is awesome, and can really create some beautiful images. You will love this lens if you prefer to go out and take pictures instead of shooting test charts. I don't need a chart to tell me its center sharpness is superb, because it blows away my old Nikkor 50mm f/1.4 D. If you are creating beautiful images, then chances are you corners will be out of focus anyways.reviewed January 3rd, 2009 (purchased for $370)
People also complain about focusing issues, I can say that my copy is right on the money on my Canon 40D, and being in correct focus is way more important than corner sharpness. The focus is sure footed and pretty snappy, although not quite as quick as my Canon 70-200mm f/2.8 L, it is more than adequate for all uses.
If you are looking at the alternatives to this lens on the Canon side, like I was, then in my opinion you won't find a better offering for the money. The Canon 28mm f/1.8 and 35mm f/2 are both fine lenses, but share similar or worse image quality and are built worse and about a stop slower. If you have the money to jump to the "L" alternatives then more power to you, as I am sure they are better than this MUCH cheaper alternative, but the price/performance isn't worth it to me on a DX camera.
So in conclusion I have been really impressed with my copy of this lens and I highly recommend it for those seeking a fast normal lens.
