Rodenstock 90mm HRSW (Yellow Band) Cambo (WRS) Tilt/Shift
Excellent image quality and large usable image circle.
Purchased it from Capture Integration last year but I'm more of a wide-angle guy.
I'll probably replace it with a Rodenstock 50HR T/S or maybe even the 23HR.
Price: $6900 (including insured shipping in US and Paypal fees)
