Pentax smc Pentax 6x7 75mm f/4.5 Shift - Pentax 67 Mount

This unique lens for the Pentax 67 system provides perspective control through a shift mechanism. It allows for up to 20mm of shift, which is invaluable for architectural photography to correct converging verticals. The lens is manually operated and features a rotating mechanism to allow shifting in different orientations. It offers a moderate wide-angle perspective on the 6x7 format. Verify that the shift mechanism moves smoothly and locks securely in place. SDS checks the rotation mechanism for excessive play and ensures the optics remain centred throughout the shift range. As a complex mechanical lens, check for any wear in the adjustment knobs. Ensure the glass is free from scratches, as the large front element is relatively exposed.
