The Smart Expander features a 1.26x magnification factor, expertly matching the image circle of full-frame Canon EF lenses to the medium-format sensor of GFX series cameras. This ensures that the diagonal field-of-view (FOV) remains consistent, providing you with the same high-quality images you've come to expect from your Canon lenses.
The optical design of this lens adapter is comprised of five elements in three groups. It incorporates ultra-high index Lanthanum-based optical glass and one element made of fused silica. This results in exceptional performance, particularly with professional-grade f/2.8 zoom lenses. For instance, a 24-70mm f/2.8 lens transforms into a 30-88mm f/3.5 zoom, and a 70-200mm f/2.8 lens becomes an 88-252mm f/3.5 zoom.
The Smart Expander also features Metabones' electronic integration, including phase-detection autofocus (PDAF), in-body image stabilization (IBIS), optical image stabilization (IS/OS/VC), and smooth iris. This allows for seamless operation and superior image quality, regardless of the lens used.
Metabones has a reputation for designing and manufacturing lens adapters that are recognized for their superior design and workmanship. The Canon EF Lens to Fuji G-Mount T 1.26x Smart Expander is no exception. It features precision-machined brass with chromium plating on both the camera-body and lens sides, ensuring smooth mounting, an attractive appearance, and long-lasting durability.
The lens side of the adapter features a robust leaf-spring structure, strengthening the adapter-lens connection and ensuring a tight fit. This reduces wear and prevents focus errors and optical alignment issues. With its matte-black treatment to minimize internal reflection, this adapter maintains the maximum optical quality possible with your lens.
In summary, the Canon EF Lens to Fuji G-Mount T 1.26x Smart Expander is a versatile and high-quality tool that allows photographers to use their existing Canon EF lenses with Fujifilm GFX cameras, providing greater flexibility and compatibility in their photography.
