To answer your question on reducing the iso from 400 for handheld shots...
Your 16-85VR has an aperture of F3.5-F5.6, if can you find a lens that has the same filter thread as your B+W 093 AND has an aperture of F1.4 or F2.8, it will let in more light, reducing the need for a higher ISO.
This image was taken with an aperture of F7.1 (which lets in less light to the sensor) so maybe also shooting in A mode will give you more control? (with possible loss of overall sharpness in larger apertures)
Faster lenses, that work in IR too? I don't know of any I could afford - the 17-55 Nikkor is bad in IR (!), all the 3rd party fast zooms (Sigma, Tokina, Tamron, etc) are crap in IR too. Older fast primes have hotspots, newer fast primes, or more recent fast zooms (14-24, 24-70, or 17-35) all cost an arm or a kidney. And I don't have any spare arms or kidneys...
Actually, the trick is in the neck-strap as I've found out. When I hold the camera away from me, as far as the strap allows, so that it almost hurts in my neck, well, then the shot will be sharp most properly.
Try here for some good nikon lens' they have a bargain basement too :- [link]
Nice to know about the sweet spot on the 12mp APS-C Sensor (cmos) as I thinking about picking up a D7000 (also a cmos but 16.2mp) or a Canon 7D/60D and will keep that in mind.
For visible light, check the different lens review sites for the optimal settings - photozone.de, slrgear.com, etc.
thank you
