Very nice to see how S lenses look on the GFX, Michael. Having been shooting 6x7 for several years now I've come to prefer 4:3 aspect ratio, but I do miss S lenses.
Too bad there's not enough of a market for Fotodiox (or some other company) to reverse engineer S lenses' AF and aperture protocols.
For over a year, Adorama was selling a set of Thalia cine lenses on eBay (and then on their website) for something like $180k (and then successively discounted). The lenses appear to have been sold. They would've been an exorbitant way to do Leica on Fuji.
