Weighing just 370g and measuring a mere 72.4mm in length, its compact design does not compromise on image quality. The lens boasts an advanced optical structure featuring one SLD and one FLD element, alongside three aspherical elements, ensuring sharp, high-contrast images with minimal chromatic aberrations. Its robust, all-metal construction is weather-sealed for durability, making it an excellent choice for outdoor photography. With its bright f/2.0 aperture, this lens is not only ideal for capturing expansive landscapes and architectural details but also for intimate indoor settings where lighting is a challenge.

More Details:

• Compact and Portable: At just 370g and 72.4mm in length, this lens is incredibly easy to carry, perfect for photographers on the go.
• Exceptional Low-Light Performance: Thanks to its f/2.0 maximum aperture, it excels in low-light conditions, allowing for stunning shots with a shallow depth of field.
• Superior Optical Quality: The lens incorporates one SLD and one FLD element, along with three aspherical elements, to produce sharp, clear images with minimal aberrations.
• Robust Construction: Designed with an all-metal body and weather-sealing, this lens is built to withstand challenging shooting environments.
• Versatile Wide-Angle Perspective: Ideal for capturing expansive landscapes, architectural marvels, and interior spaces with its wide 94.5° angle of view.
• Smooth Bokeh: A rounded 9-blade diaphragm contributes to a pleasing out-of-focus quality, enhancing portraits and close-up shots.
• Precise Focus Control: Achieve critical focus with ease, thanks to its smooth and accurate focusing mechanism, suitable for both photo and video work.

• Premium Compact Primes for mirrorless users - The combination of superb optical performance with a level of compactness that is perfectly suited to smaller and lighter modern mirrorless cameras will bring you new opportunities for a perfect shot.
• New standards of optical performance for the Contemporary line - Based on the latest optical design technology, the lens construction includes three high-precision glass-molded aspherical lens elements, one SLD element, and one FLD element to suppress a range of optical aberrations. The result is clear and sharp images even in the extreme corners of the frame.
• SIGMA’s unique coating technology Nano Porous Coating - “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 with conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.
• Magnetic metal lens cap - This dedicated metal cap clips to the front surface of the lens magnetically. It is no exaggeration to say that this meticulously crafted cap represents the finishing touch for the I series.
• Inner focus system - To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
• Stepping Motor - The lens is capable of smooth, quiet, and high-speed AF made possible by a stepping motor, as well as supports Face/Eye Detection AF and video AF.
• Super Multi-Layer Coating - In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, SIGMA’s Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.
• Aperture ring - designed to help users work intuitively.
• Focus Mode Switch - Using this switch, it is possible to switch the focus mode between AF and MF.
• Mount with Dust and Splash Resistant Structure - The lens mount incorporates rubber sealing to protect the mount from dust and water drops.
• Compatible with high-speed autofocus
• Designed to minimize flare and ghosting
• Every single lens undergoes SIGMA’s proprietary MTF measuring system
• 9-blade rounded diaphragm
• High-precision, durable brass bayonet mount
