Laowa Magic Format Converter MFC - Canon EF - Fuji GFX

Laowa Magic Format Converter MFC – Adapts Canon EF full-frame lenses to Fuji GFX by expanding the image circle

The Laowa Magic Format Converter (MFC) lets you use Canon EF full-frame DSLR lenses on medium-format bodies such as the Fujifilm GFX. It increases the image circle of your existing full-frame optics so they cover the larger medium-format sensor. As a result, you can achieve wide-angle perspectives and very high-resolution images without vignetting or loss of detail when the conversion is appropriate for the lens.

How the MFC works

The Magic Format Converter optically expands the coverage of full-frame lenses so their image circle better matches medium-format sensors. It preserves key optical characteristics of the original lens — including sharpness, contrast, and color fidelity — while enabling a seamless transition from full-frame to medium format. This makes it a practical solution for photographers who want to use familiar lenses on a larger sensor platform.

Construction and optical design

The converter uses precision-engineered glass elements to minimize aberrations and distortion. This optical design helps maintain excellent edge-to-edge sharpness across the expanded image circle. Additionally, the device features a durable all-metal housing built for long-term professional use, while its compact and lightweight form factor keeps handling comfortable and avoids adding excessive bulk to your camera setup.
