Large Aperture, a must in low light shooting
performs much better than the f1.8 version in low light shooting, as it is 2/3 a stop larger in aperture setting than f1.8
fast focus in good lighting condition
fast tracking under good lighting, sport able if under sunlight (outdoor sport like street basketball) as it is what i tried with friends
very light weight weight, and small in size
try spot metering mode on Camera and shoot portrait without flash, you will love its result and be blown away, as it is amazing (on a D3)
缺點:
will lose focus if lighting condition is poor
not AF-S
no special glass like (ED, Nano,)
f1.4 is easy to lose sharpness if not used on Tripod, or if shooting with kids who really moves, try setting it to f2.8 is a better bet to make object sharp, (f4 to make full face sharp)

I am still using a SB-800 which does not support the D3, D300's 51 points AF system, it is pity that the AF assist of SB-800 wont be much of a great help in assisting your focusing needs in dim light, if you really love this lens and will shoot with flash, you must get a SB-900 to make full use of new camera with this lens,
it is very very sharp, dont push your camera's sharpness too much, as it will make the images look wired, hair is a big concern when there's too much sharpness, and the sky may look wired too,
it is indeed the best lens nikon has to match with cameras like D3, and D700, a wonderful point and shoot lens, and excellent low light capability, at a very very affordable price
