For Canon, it's the lenses marked USM that allow you to manually focus without having to switch out of auto. I was wondering what the code was for Nikons, thanks Vincent!

Most likely you're using a consumer DSLR, and that means the viewfinder is like looking through a dark tunnel... A dark mouse-sized tunnel. Making manual focusing hard enough in daylight. I find a lens with distance on it incredibly useful for shooting in the dark One thing i could suggest is to use a lens with distances marked on it.

If you try this without though (as in, your camera motor is driving the focusing), you could damage the internals, so be careful. This is mostly an issue with 50mm lenses, haven't tried this with the sigma 30mm. My telephotos do support it however.
