Metabones Nikon G to Nikon Z-Mount Speed Booster ULTRA 0.71x Adapter, Matte Black

What sets the Nikon G to Nikon Z-Mount Speed Booster ULTRA 0.71x Adapter apart is its exceptional optical enhancement capabilities, designed to elevate the performance of your Nikon Z-mount camera system. This matte black adapter features a sophisticated 5-element/4-group optical design, which includes ultra-high index tantalum-based optical glass. This advanced composition not only ensures improved corner sharpness but also significantly minimizes distortion and vignetting for pristine image quality.

The Speed Booster ULTRA's 0.71x magnification factor is a game-changer, effectively reducing the crop factor of DX-sized sensor mirrorless cameras from 1.5x to approximately 1.07x. This transformation allows photographers to achieve a wider field of view and increased maximum aperture, turning professional-grade lenses into even faster tools for capturing images.

For instance, with this adapter, a 24-70mm f/2.8 lens becomes a 17-50mm f/2.0 lens, and a 70-200mm f/2.8 lens is converted to a 50-142mm f/2.0 lens, offering remarkable speed and versatility. Fixed focal length lenses also benefit significantly; a 50mm f/1.2 lens is effectively transformed into a 35.5mm f/0.9 lens, delivering extraordinary contrast and resolution across the entire image frame.

The Speed Booster ULTRA is meticulously engineered to work with a wide array of full-frame SLR lenses, ensuring high-quality performance even with lenses that have varying exit pupil distances. This makes it an indispensable tool for professionals who demand the utmost optical excellence.

Please note that certain lenses are not supported by this adapter. Specifically, Nikkor DX lenses and third-party APS-C format lenses are incompatible due to image coverage limitations. Additionally, certain Nikkor lenses, including the 2.1cm f/4 and AI-S 20mm f/2.8, as well as E series lenses with electronic diaphragm control, such as the 105mm f/1.4E and various AF-S models, will not operate with the Speed Booster. This adapter is designed for manual aperture control and does not support electronic aperture control, autofocus (AF), or image stabilization features.

In summary, the Nikon G to Nikon Z-Mount Speed Booster ULTRA 0.71x Adapter is a cutting-edge tool for photographers looking to maximize the potential of their Nikon Z-mount camera system with enhanced optical performance, wider apertures, and expanded creative possibilities.
