Metabones ALPA to Sony E-mount Speed Booster ULTRA 0.71x (Black Matt)
The Metabones ALPA to Sony E-mount Speed Booster ULTRA 0.71x (Black Matt) allows ALPA lenses to be used on Sony E-mount cameras while increasing light transmission and widening the field of view. Featuring advanced optics and premium construction, it delivers enhanced image quality with sharper details and reduced distortion.
This high-performance lens adapter is designed to bring ALPA mount lenses to Sony E-mount cameras with enhanced optical performance. Incorporating the renowned Speed Booster ULTRA technology, this adapter reduces the effective focal length by 0.71x, resulting in a wider field of view while simultaneously increasing the maximum aperture by approximately one stop for improved low-light capability.
At the core of this adapter is an advanced 5-element, 4-group optical design developed with ultra-high index tantalum-based optical glass. This sophisticated construction significantly improves image quality by delivering sharper corners, reduced distortion, and minimized vignetting, even when used with high-end full-frame lenses.
Designed with precision and durability in mind, the adapter features a robust metal construction with a sleek black matte satin finish. It also includes a detachable tripod foot that is fully compatible with Arca-Swiss, Markins, and Photo Clam tripod systems, offering stable and flexible mounting options for professional shooting setups.
Optimized for APS-C format cameras or crop modes on full-frame Sony E-mount bodies, the Speed Booster ULTRA effectively reduces crop factor and maximizes lens performance. Whether using fast prime lenses or professional zoom lenses, this adapter ensures excellent contrast and resolution across the entire frame.
