Sony FE 14mm f / 1.8 GM Lens - Portable and lightweight, the FE 14mm F1.8 GM lens delivers high resolution and superior contrast thanks to advanced optical technology. Two advanced XA-type aspherical elements allow for excellent detail throughout the frame, even in the corners. Two ED elements with extra-low dispersion and one Super ED element compensate for chromatic aberration and improve contrast at all apertures. The maximum aperture of F1.8 allows you to take high-quality pictures with point light sources. Signature Nano AR Coating II improves micro-contrast and detail by reducing glare and color spots.
