fastest low-light focusing lens for nikon?

[just x joey]

i need a really fast lowlight focusing lens for my d80, preferably a semi wide angle, less than 80mm.

Garbz gave this link. Maybe it will help.

AF 50mm f/1.4D probably one of the fastest low light lens available. But, you already have the f/1.8 version, I don't see any big advantage having both 50s in your arsenal.

May I ask for what purpose? The 50mm f/1.4 won't be any better in low light focusing than your f/1.8. What may suit you better is an SB-600, SB-800 or if you don't want a flash the wireless commandar unit for the camera. They have red/ir hatched focusing assist lights on them which work significantly better than the little focusing light on the camera.

Are you asking about fast as in lowest aperture or fast as in focus?

If the former then you are not likely to want anything less than f1.4 due to an f1.2 (seems like there was an f1.0 made somewhere back yonder) being softer.

If focus speed then I would think an -S lens would be it. I haven't really paid attention but my 18-70 AF-S doesn't tend to miss.
