Vistek has this on sale, $4200 discount, which seems an aggressive price compared to other retailers. Other Canadian retailers are asking $5200 just for the body and the 75mm lens alone is about $900Cdn. With the premium on the US dollar you're looking at less than $4000 for the body/lens combo. I'd be crazy to go for it, but the meter prism on my old 6x7 has just quit . . . Heck of a deal for someone wanting to move into digital medium format.
