I know these electronic lenses don't give you focus distance marks, but I'm wondering if anybody knows if the A1/G1 lens gives you a distance readout in the viewfinder (as the Z1 does), and if it's repeatable.

Yep and yep. http://www.dvinfo.net/conf/showthread.php?t=73131

Excellent. I thought I had read that someplace but couldn't find the right thread.

Presumably it'll be the same or at least similar to the technology in the H1. I haven't pulled out the tape measure to prove to myself that it is spot on the mark, but it is repeatable from a practical standpoint. Works quite nicely for me.
