There seem to be two very different shades of 'Hartblei" out there, with old and new products selling at almost 10x difference.Check out the $600 35mm superrotatorhttp://www.hartblei.com/lenses/lens_35mm.htmvs. the $5,000 40mm Hartbleihttp://www.hartblei.eu/en/srz-set.htmor is it the $ 40mm Rodenstock Digaron? http://www.adorama.com/catalog.tpl?op=News...e_num=092508-4aI am not all that happy with the resolution of my Canon 45mm TS-E, although it is a decent lens. Ive been thinking of a Zork adapter, or the 35mm Hartlblei... when I hear about this mysterious 40mm Tilt shift that by the price of it appears it would be made of solid gold. Dipped in Platinum.
