Also look into speedlite flashes. They will help a lot with kit lenses getting enough light into your tank. Yongnuo speedlites are inexpensive and very good. Cowboy Studio triggers are also inexpensive and very good.

Any lens with a maximum aperture of f/2.8 or larger is considered a fast lens. A maximum aperture of f/5.0 or smaller is generally considered a slow lens.
Yeah the 50mm prime lens that was suggested in my tank thread would be good but to get a FTS with it requires that I stand really far from the tank...a 35 mm will allow a little more versatility I think.

I definitely see the issues with my lens regarding the larger aperture.
