When I recently purchased a 30mm F1.4 fixed focus lens I explained my reasons for doing so while reviewing the lens. Today I realised I left out yet another reason to add a fast fixed-focus lens to your collection. Because fast lenses gather insane amounts of light you can shoot hand-held at night and actually get good results. I did manage to get some night time images before using the standard 18-55mm zoom that comes as part of the Nikon D40 kit, but that was really working at the limit (see the results here). Because that lens is quite slow at F3.5-5.6 I had to crank the ISO up to 1600 and even then the exposure times were still very high. This resulted in images that were grainy and a lot had to be junked because they were blurred to a greater or lesser extent.

On my way home from work this evening I had a go at some night time photography with my new F1.4 lens. It was such a nice experience! With the ISO turned down to 800 I could easily take hand held shots that look pretty good.
