The problem with 99% of the lens adapters made for the Pentax 110 lenses is that you can't control the f/stop. All exposures are made "wide-open", reducing resolution, depth-of-field and preventing complete control over exposure.

This custom adapter with variable aperture solves that problem to some extent by allowing some control over exposure when used with Panasonic and Oympus Micro 4/3 cameras.

This adapter is custom made, all metal, with a spring-loaded finger operated aperture contol arm (pictured in red).

Pentax lenses lock in securely and focus to infinity.

Depending on the model of your camera, the Pentax lenses may be used in Manual, Aperture Priority or Program modes.
