Pentax smc Pentax 28mm f/3.5 Shift - Pentax K Mount

The smc Pentax 28mm f/3.5 Shift is a specialist manual focus lens designed for architectural photography. It allows for 11mm of shift movement to correct converging verticals, keeping buildings looking straight without the need for post-processing. Unlike modern perspective control lenses, this K-mount lens is relatively compact and features a built-in rotating tripod collar and internal filters (Y2, O2, R2, and Skylight) selected via a ring. When inspecting this lens, the shift mechanism is the most critical component; it should move smoothly and lock firmly without slipping. SDS checks the internal filter turret to ensure it clicks into place and that the glass remains clear. The rotation of the barrel should be fluid, allowing for shifts in any direction. Verify that the glass is free from scratches, as the front element is somewhat exposed.
