Also used on APS-C E-mount cameras, its constant f/4 maximum aperture offers consistent performance even in low-light situations. Its Optical steady shot image stabilization feature helps in minimizing the appearance of camera shake. The lens includes five aspherical elements with an advanced aspherical element of large diameter and three ED (extra-low dispersion) elements to help reduce chromatic aberrations. The moist and dust resistant lens elements has been applied with a Carl Zeiss T anti-reflective coating to minimize lens flare and ghosting.
