New 645 lenses

There is a PENTAX smc D FA 645 90 mm / 2,8 on the horizon this year: CP+ 2012 - Neuheiten / 645D Image Transmitter Software - Nachrichten - Division Imaging Systems - PENTAX Photo
Leichtes Teleobjektiv, optimal für Porträtaufnahmen mit besonderem Bokeh
Markteinführung 2012

As well as a DA 645 25mm version of the DFA one if I understand things correctly.

Anyone using 645D glass on K-mount? The new 90mm f/2.8 looks interesting enough to try. Adapter commendations?

You will need this adapter: Pentax-K Adapter for 645 Reviews - Pentax 645 Teleconverters and Adapters - Pentax Lens Reviews & Lens Database

Medium format lenses are sharp and all, but I don't think it's worth the drop in overall handling when used with k-mount cameras.

I would probably be better off with a 100mm macro. or a good A* lens.... Really disappointed Pentax has not released a 90mm f/1.4 or 135mm f/1.8 for K-mount.
