Lens board M39 for Durst and Meopta (78mm, -15mm)

• Focusable with short focal lengths: The 15 mm recess brings the lens closer to the negative plane—50 mm lenses can still focus even when the bellows draw is fully retracted.
• Replacement for the Durst Setopla 2839: Lens board for Durst enlargers with a 78 mm mount (Lapla standard), featuring an M39 thread for common enlarger lenses.
• Matte black to reduce stray light: The matte material minimizes reflections in the optical path for clear contrast.

Description

With this Lapla lens board, you can install an enlarger lens with an M39 thread in your Durst enlarger with a 78 mm mount. The integrated 15 mm recess solves a common mechanical problem in larger devices such as the Laborator 1200, M800, or M805: The bellows often cannot be compressed far enough to focus 50 mm lenses (for 35 mm film) on the baseboard. The recessed mounting brings the lens closer to the negative plane, making the required focusing range accessible again.

The standard M39 thread accommodates most common enlarger lenses.
