I'm looking to add a wide-angle prime lens to my collection. I've used a 28 mm enough to have a feel for the look. But I am wondering what a 24mm would do. ( BTW, my camera is a Nikon F100.) One problem I am curious about is what do you do with all that context?? It appears to me that if I'm not very careful with composition that I will wind up with a lot of nothing much in the frame. In other words, how much of a challenge to one's composition skills will the 24mm engender? Or would a 20 mm be even more challenging? If you are going to recommend a manual focus lens, please bear in mind that I really, really like the Matrix metering and the other two as well. I already have some FSU rangefinders that require the use of a hand-held light meter.

Thanks to all who reply.

With best regards,
