SIGMA’s unique coating technology Nano Porous Coating
The super multi-layer coating is combined with SIGMA’s unique coating technology "NPC (Nano Porous Coating)". The lens has been designed to be less susceptible to strong incident light such as backlight.
"NPC (Nano Porous Coating)" incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.
About the shortest shooting distance
The minimum focusing distance is 18 cm at the wide-angle end. This allows you to come closer to a subject than the end of a hood to take photographs*. The maximum magnifications are 1:2.9 at the wide-angle end and 1:4.5 at the telephoto end, which provides a wider range of expression by close-up photography.* Be extremely careful that the front lens element does not hit the subject when photographing. Remove the lens hood from the camera body before use when photographing at the minimum focusing distance at the wide-angle end.
Designed to minimize flare and ghosting
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. In addition to Super Multi-Layer Coating, Nano Porous Coating is employed. These coatings reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
Hood with lock
Features a hood with lock to prevent dropping the hood.
Rounded diaphragm (11-blade)
The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
