Long lenses for the R-D1

[Terao]

I'm looking at getting either the VC 75 or 90. Am I likely to be able to accurately focus either of those on the R-D1? Are there accessory finders available?

I can focus my VC 75 reasonably well on the RD1. Actually I get even very usable results from a noctilux wide open. This is however only possible for me after ajusting the lens a bit (you can do that by uncrewing the head of the old noct) to compensate for malajustment of my finder.

I'm looking for someone who can ajust my finder in NL. (not epson. I've lost my patience with them)
