Rayqual NFG-M4/3 Adapter for Nikon G Lens to (MFT) Micro Four Thirds Mount Review

The Rayqual NFG-M4/3 is a precision lens adapter that allows Nikon G-mount lenses (which lack a manual aperture ring) to be used on Micro Four Thirds camera bodies. Rayqual is known for manufacturing high-tolerance adapters with tight machining, and this model is designed to maintain proper flange distance and infinity focus when pairing Nikon glass with MFT cameras from Panasonic, Olympus, and others. The adapter includes an aperture control ring to adjust Nikon G lenses, which is essential since these lenses cannot be controlled electronically on MFT bodies.

At $153, this adapter sits in the premium tier for mount adapters. It competes with options from Fotodiox, K&F Concept, and Viltrox, which typically cost less but may not offer the same build precision. The adapter is manual-only, meaning no autofocus or electronic aperture communication, so users will need to focus and set exposure manually. This makes it best suited for deliberate shooting styles like video work, portraiture, or stills where manual control is acceptable. The crop factor (2x on MFT) will turn standard Nikon lenses into longer focal lengths, which can be advantageous for telephoto work but limiting for wide-angle applications.
