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.
Substantial functions enable user confidence, even in tough environments
Incorporating a stepping motor enables the high speed, quiet AF drive. Shooting is comfortable even in target AF such as Face/Eye Detection AF and during video shooting. The AFL button1 which can be assigned with various functions widens the range of operations available on the lens. Furthermore, the lens features a dust- and splash-proof structure2, along with a water- and oil-repellent coating on the frontmost surface of the lens, which further supports shooting in various environments.
Rear filter holder as a standard accessory
The lens comes with a rear filter holder equipped with a fall prevention lock for attaching sheet type rear filters for shooting starry skies.
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. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
Compatible with Lens Aberration Correction
Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
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.
