The sophisticated Sonnar optical design enables high resolution and sharpness with optimized low-light shooting capabilities. A Carl Zeiss T* anti-reflective coating has also been applied to lens elements to reduce lens flare and ghosting for improved contrast and color fidelity. Additionally, a dust- and moisture-resistant construction ensures this lens’s use in tough environmental conditions. This prime normal-length lens features a bright f/1.8 maximum aperture to benefit working in low-light conditions and for greater control over the plane of focus. Carl Zeiss T* anti-reflective coating lessens lens flare and ghosting for contrast-rich imagery with sustained color neutrality. Dust- and moisture-resistant design enables ensured performance when working in inclement environmental conditions. Nine-blade circular diaphragm enables a smooth out-of-focus quality that is well-suited to shallow depth of field imagery.
