Metabones Speed Booster Adaptor - Leica R to E-Mount ULTRA MB_SPRL-E-BM2

The Leica R Mount Lens to Sony E-Mount Camera Speed Booster ULTRA from Metabones improves upon the original Metabones Speed Booster with a 5 element/4 group optical design that incorporates ultra-high refractive index tantalum-based glass for improved sharpness and reduced distortion and vignetting. The Speed Booster ULTRA allows a full frame Leica R Mount lens to be mounted to an APS-C format E-Mount camera and in doing so, increases the angle of view and increases the maximum aperture by approximately one f/stop.

Key Features:

• Allows a full frame Leica R Mount lens to be mounted to an E-mount APS-C format camera and in doing so, increases the angle of view and increases the maximum aperture by one f/stop.

• The Speed Booster ULTRA design incorporates ultra-high index tantalum-based optical glass for enhanced optical performance with improved corner sharpness and reduced distortion and vignetting. This glass technology and optical design perform extremely well with professional-grade f/2.8 zoom lenses and high-speed fixed focal length lenses such as a 50mm f/1.2 which will perform as a 35.5mm f/0.9 lens with high contrast and resolution from the center to the edges of the image.

• Precise fit and solid connection

• Infinity Focus Adjustment

• Detachable Tripod Foot

• Black Matte Interior; Black Exterior
