This innovative optic offers fast and precise AF and superior operability, making it an ideal choice for full-frame film-makers and stills photographers. The lens features a constant maximum aperture of F1.8, a practical and stable inner zoom mechanism, and a constant 30cm focusing distance across the entire zoom range. It is lightweight at less than 1kg and uses a versatile filter size of φ82mm. The lens's optical quality is achieved through the use of 5 SLD elements and 3 aspherical elements, which suppress aberrations and allow for clear images with minimal coloration. The lens also suppresses focus breathing, enabling natural focus pulls when shooting video. Additionally, the lens eliminates flare and ghosting using advanced simulation technology and SIGMA's Nano Porous Coating and Super Multi-Layer Coating, ensuring clear, saturated images in all lighting conditions.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eProduct Highlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Lens construction: 18 elements in 15 groups (5 FLD, 3 aspherical)\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Inner zoom\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Inner focus system\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Compatible with high-speed autofocus\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Dual HLA (High-response Linear Actuator)\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Compatible with Lens Aberration Correction (for supporting cameras; on cameras where lens aberration correction is controlled with ‘ON’ or ‘OFF’ in the camera menu, please set all aberration correction functions to ‘ON’ (AUTO))\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Support for DMF, AF + MF\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Compatible with AF assist (Sony E-mount only)\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Nano Porous Coating\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e•  Super Multi-Layer Coating\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e• Water and Oil Repellent Coating (front element)\u003c\/p\u003e\n\u003cp style=\"padding-left: 30px;\"\u003e•  AFL buttons (2 buttons) (Only on compatible cameras.
