Focusing Screens - do you use alternates?

jibbon: does it black out easily? im pretty worried abt that matter tho.

since my only workhorse lens is either the 35 1.8 or 10-20! afraid if i turn to the 10-20 it gets too dark too early!

It does black out, but I wouldn't say easily. I haven't noticed it hapening particularly with the 10-20. It's better than the one that came with my Ricoh XR-M. (That was circa 1979!!)

The K10D has focus confirmation which I check & find that it invariably agrees with the split prism.

I have certainly found it an enormous advantage when focusing manually in cases, say, if you are trying to focus on a single particular flower on a bush with a whole bunch.

I don't understand the pros to changing it, is there any?

There's one enormous pro to using a split prism focusing screen. Ability to focus on an object in a clutter of objects where you want a shallow depth of field i.e a single chilli on a chilli bush & the surround out of focus. The Autofocus doesn't know exactly which chilli or leaf or stick or branch that you really want. The split prism will allow you to tell the camera when to take the shot by manually focusing.
