- Why do you want a split or microprism screen? First off, with
- AF, you don't need focusing aid. Second, if you ever use a fast
- lens, you'll know that split screen or microprism is useless. A fast
- lens has such small DOF that unless you are lucky, there won't be
- enough feature for the split screen to split or microprism to merge
- (for example, a tight head shot with a 1.2 lens that has a DOF of about
- 1/4", where are you going to find vertical feature on someone's face
- to split the split screen? If you focus on say the person's arm to
- use the split screen, her face won't be in focus anymore.) One of the
- few things that I like about AF cameras (obviousely, I don't use one)
- is that they all seems to have bright plain focusing screen. I
- absolutely hate it whenever someone hand me their camera with that
- pin hole zoom and all you see is that black blob in the middle of the
- focusing screen.
