Find the ultimate solution to enhance your photography experience with the Metabones Minolta Md Lens to Sony E-Mount Camera Ultra Speed Booster. This innovative device, finished in a sleek matte black, is designed to optimize the performance of your full-frame Minolta Md lens when mounted on an Aps-c format E-Mount camera. The Ultra Speed Booster boasts a sophisticated 5 element/4 group optical design, incorporating ultra-high refractive index tantalum-based glass. This advanced feature ensures improved sharpness, while significantly reducing distortion and vignetting, resulting in crystal-clear, high-quality images. One of the key benefits of this Speed Booster is its ability to increase the angle of view and the maximum aperture by approximately one f/stop. This is achieved by condensing the light from the lens and projecting it onto the Aps-c sensor, allowing the sensor to utilize all of the lens' light. This effectively reduces the crop factor of an Aps-c E-Mount camera from 1.
