Metabones Speed Booster ULTRA 0.71x EF para E Mount

By using advanced optics, this adapter increases the apparent angle of view of a Full Frame lens by 0.71x, effectively counteracting the crop factor of an APS-C or Super 35mm camera. It also enhances image sharpness by increasing the maximum aperture by 1 stop, allowing the Full Frame lens to perform as if it were mounted on a Full Frame camera.
