Excerpt: LOVED this lens, but I had to return it because it was simply too expensive for my budget.<br /><br />Super sharp. Great in low light. Not quite the all purpose lens that 1.4 50mm is, but for cramped interiors and night work, it's hard to beat.
Pros: Built like a tank, Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Low light superstar, Nice Bokeh, Pro consruction, Rugged, Strong Construction, Super sharp
Excerpt: I've been on a prime kick lately, and recently added this and the Nikon 85mm F1.4G lenses to my arsenal. Compared to the 85mm, performance at F1.4 isn't quite as good, but it's good enough (that's the only downside of this lens from what I can tell). The bokeh it produces for a wide angle lens is pretty amazing and stopped down a little bit, this lens is SHARP.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh
Summary: Saved me $2,200!! Anyways, I thought it was a very good lens. I did not think it was outstanding. What keeps it from getting 5 stars with me? Well, that auto focus that you can call 'leisurely' at best. In a slightly dimmed room (certainly not dark), with many xmas lights on, tv going, autofocus really had a lot of trouble locking on. In fact, it was all over the place! Again, this was not a dark room! Typical room with some incandescents, xmas lights, tv on, etc.
Summary: Since I purchased this lens a couple of months ago, I basically have not taken it off my D300s. The brightness and the depth of field are perfect for the gloomy winter indoors. However, as others have mentioned, you cannot just go around snapping shots like crazy. Even with spot center focus, and even shooting three or four shots in a row of the same subject, the object in the center is very likely to remain blurred.
Summary: i'm a novice with few DX bodies including D5100 with 85mm 1.4G. I just got this 24mm 1.4G lens yesterday and i'm not sure about it, thinking of returning it because my camera can't handle it. it's not that sharp as 85mm 1.4G or 105mm 2.8G macro, it focus takes time and wanders, every other photo are not in focus. it works well in close up but in normal shooting like scenery or distance it's average looking.
Summary: Look, everyone needs to evaluate what their kit will consist of. Are you carrying zooms or primes? If you're a prime shooter, the 24, 50, 85 are great lenses. Maybe even the 105 micro. However, this lens is as good as it gets for a wide angle prime lens. Sure, there are wider choices, but @ f1.4 you get a pretty darn fast lens. More importantly, on a DX sensor, you're getting a 35mm...one of the best focal lengths available for every day shooting.

Summary: I have a love hate relationship with this lens and it mostly comes down to my skill as a photographer, however make sure that you get a copy of this lens that auto-focuses correctly with your camera bodies. I had to return my first copy because I couldn't get consistent focus with my D700 or d300s even while using the focus adjust in camera.
Summary: Others have said it better, more eloquently and in more detail but I wanted to toss my two pennies in. Phenomenal glass if you can justify the price tag. As a wedding photographer I shoot a lot at 24mm (wide shots of the ceremony and a lot during reception dancing) and I really wanted the shallow DOF for subject isolation. Stupid sharp from corner to corner, even at f/1.4.
