Hi,
Thanks for the answers ... some follow-up:

Well, I'm not opposed to spending some dollars (but not $300) to solve this.
This "dual body" solution had occurred to me, and now that I'm confirming I've
got as few options as I feared, I can reconsider it.
What would be "the" screen to have? Is there a concensus on which one?

This sounds very promising. Have folks had good personal experience with the
Varimagni and the standard prism while doing macro work?

Now here's the one part I don't understand. I was shooting in full sunlight,
so I don't think more light would help ...
For somebody else that asked what the "matched close up lens" really was --
sorry to mix my terms. It is a close-up lens that screws on to the filter ring
in front of the front element. It's matched in the sense that it is sold
specifically with that lens and is intended to specifically provide the 1:1 at
absolute close focus.
Again, thanks for the explanation as to why the split prism was going dark on
me as I neared 1:1. I don't claim to understand the optical issues involved
but the explanation given makes sense.
Also, another responder mentioned zooms as a means of solving the minor close
adjustments. Thanks, that may be acceptable in more circumstances then I'm
usually considering, so I need to give it a try again.
Looking forward to feedback on which screens are best and also experiences you
all may have had with the varimagni and the standard split prism while doing
macro.
