APRANET Pentax K Lens to Micro Four Thirds Camera Mount Adapter

Owning a collection of Pentax K-mount lenses doesn't mean you have to leave them behind when switching to a Micro Four Thirds camera. This APRANET adapter bridges the gap, letting you mount your trusted PK glass onto any M4/3 body without compromising infinity focus or build quality.

Who is it for

Photographers and videographers who want to reuse their existing Pentax K lenses on modern Micro Four Thirds cameras, such as Panasonic Lumix, Olympus OM-D, or PEN series bodies. It's ideal for manual focus enthusiasts, budget-conscious shooters, and anyone looking to expand their creative lens options without buying new glass.

Tips

When using this adapter, set your camera to 'Release without lens' mode (if available) to allow shutter actuation. Since there is no electronic communication, you will need to use manual exposure or aperture-priority mode and focus manually. For best results, use focus peaking or magnification aids on your camera body. Always attach the adapter to the lens first, then mount the combination to the camera to reduce stress on the mount.
