FEATURED REVIEWS
Excelent speed booster!
I tried four lenses with the speed booster:-Leica R Elmarit 24 F2.8-Leica R Elmarit 28 Mm F2.8-Leica R Summicron 50mm F:2-Leica R Vario Elmar 80-200 Mm F4.5In all cases, image quality is excellent. I did´t see vignetting when used wide open in any case. Sharpness is great. I´m happy to be able to use my Leica R lenses on my Fujifilm camera.
Love it
Excellent quality! What else do we expect from metabones :)
What sets the Metabones Leica R Lens to Fujifilm X-Mount Camera Speed Booster ULTRA apart is its advanced 5-element/4-group optical design featuring ultra-high refractive index tantalum-based glass. This innovative technology not only enhances image sharpness but also minimizes distortion and vignetting, ensuring your photographs maintain professional-grade quality.
By attaching a full-frame Leica R lens to an APS-C format Fujifilm X-Mount camera with this Speed Booster ULTRA, photographers can revel in an expanded angle of view and benefit from an increase in the maximum aperture by approximately one f-stop. This transformation effectively reduces the crop factor from 1.5x to 1.07x, granting you a full-frame visual experience on an APS-C sensor. The result is a lens that's more adept in low-light conditions and capable of producing a beautifully shallow depth of field.
The Speed Booster ULTRA excels with both professional f/2.8 zoom lenses and high-speed prime lenses, such as a 50mm f/1.2, which will astoundingly perform as a 35.5mm f/0.9 lens with exceptional contrast and resolution from the center to the periphery of your images.
Precision-engineered for a perfect fit, the Speed Booster ensures a solid, gap-free connection without any play or wiggling once mounted. Both the camera-body and lens-side of the adapter are crafted from precision-machined brass with a chrome plating, enhancing durability and providing a seamless aesthetic with your camera and lens.
The internal matte-black finishing combats unwanted reflections, preserving the utmost optical quality of your lens. The external black satin finish complements the sleek design of most camera bodies and lenses. Designed with the professional in mind, it achieves infinity focus while maintaining the correct registration distance required for lenses with floating elements or CRC.
The Speed Booster ULTRA also includes a detachable tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads, adding versatility to your shooting setup. While the adapter allows for a physical fit, it's important to note that automatic diaphragm (AE metering) and other auto functions are not supported with this Speed Booster.
In summary, the Metabones Speed Booster ULTRA is a high-quality, durable, and versatile tool that allows photographers to expand their creative possibilities by enhancing the performance of their Leica R lenses on Fujifilm X-Mount cameras.
