for what you are doing, stick with zone focusing. too much changing for most AF systems to lock onto in low light.
I'd agree... AF systems are very slow in low light no matter how fast your lens is. You could use a suitable flash that projects a spot- beam (eg AF-500FTZ) but I'm not sure if you can do this without actually triggering the flash when you press the button. Plus it's big and needs batteries.
I think that if you're having trouble with zone focus using a 50mm f/ 2, that will be more due to the focal length and resultant DOF than the lens speed. If anything, a faster lens will make your problems worse because you'll be tempted to shoot wider for either a faster shutter speed or a lower ISO.
Would you consider trying a fast 35mm lens as a compromise? BTW I really liked the first photo. Cheers, - Dave http://www.digistar.com/~dmann/
