When the 645 45mm Super rotator was reviewed a while back (doesn't have date appended) the price was quoted as c. $1000. I note the broadly similiar lens marketed as a Phase one product is c. $3000! I'm not actually in the market for this lens but I was interested in the 35mm version for DSLRs. The Hartblei website says a) the Super Rotator products are now their main business, and they are all out of stock!. Does anyone know how the 35mm performs and how much it is, when it is in stock. I thought it might be a lower cost alternative to the Canon 45mm T/S.
