S2068 Pentax 645 Lens Board

Description

Connects Pentax 645-mount medium-format lenses. With the matching camera or back adapter, the platform supplies movements for composition and focus control.

Construction and specifications

The second-generation design is 1.55 mm thinner than its predecessor, providing more room for installation and bellows movement. This is a reduction, not the total board thickness.

System configuration

Select the rear adapter and Type 1, 2 or 3 bellows for the camera or back; all three share the front board interface. TC191 currently uses four-fold bellows.

Configuration notes

Lens-side accessory only; illustrated lenses, shutters, camera platforms, bellows and cameras/backs are not included. Check retention, aperture/shutter operation, clearance, image circle and focusing range for the assembly. Movements come from the platform; mechanical mounting does not imply electronic control.
