KIPON has just released a new version of its BAVEYES adapter, specifically designed to mount Mamiya 645 medium-format lenses on Nikon Z mount cameras. It includes a 0.7x focal reducer, features a PL-style locking mechanism, and is solidly built. Let’s take a closer look!

Originally designed for medium-format film cameras, Mamiya 645 lenses have grown in popularity among filmmakers, with lenses like the fast Sekor C 80mm f/1.9 being used selectively on Christoper Nolan’s “The Dark Knight”. Given their unique vintage look and the rise of large-format cinematography, these lenses are now often repurposed for video via a budget-friendly cine-modification, a sleeve, or even a complete, high-end rehousing by specialized companies like TLS or GL Optics.

Because these lenses create such a large image circle when mounted directly on a modern full-frame digital camera, you’re not really getting the full benefit of their character. That’s why rehousing companies sometimes build in a 0.7× focal reducer. But if that kind of extensive modification is out of reach, KIPON may offer a more accessible alternative.

KIPON BAVEYES Mamiya 645 Adapter – now for Nikon Z

KIPON has been producing adapters for medium-format lenses, such as Hasselblad V, Pentax 645, Pentax 67, and Mamiya 645 series, for quite some time now. These are offered both as plain mechanical adapters or in a speed-boosted version with a built-in focal reducer.

The KIPON BAVEYES Mamiya 645 0.7x Pro Lock adapter is already offered for Sony E, Canon RF, and Leica L mounts, and now it’s also available for the Nikon Z system as well. This enables direct mounting of Mamiya 645 lenses on cameras like the Nikon ZR or the Z-mount RED V-RAPTOR [X].

I’ve personally owned the Canon RF version of the adapter for a while, and I can testify that while a bit heavy, it’s truly built like a tank. The adapter is made of aluminum, while the 0.7x focal reducer is produced by German-based company IBE Optics. This optical block makes the massive image circle converge on a smaller surface, like a full-frame sensor, for instance, revealing more of the lens’s beautiful character.

Also, since this is the “Pro Lock” version of the adapter, it offers a PL-style locking mechanism that prevents play between the lens and the adapter itself, which is essential to avoid image shift when pulling focus.

Another advantage of the KIPON BAVEYES Mamiya 645 0.7x Pro Lock adapter is that it lets you keep your lenses in their original M645 mount without requiring a hardware PL or LPL modification, so they can still be used on your Mamiya for still photography.
