The 105mm f/2.8 DG DN Macro Art is engineered to be "optically perfect" at all focusing distances. Its construction consists of 12 elements in 7 groups, including one SLD (Special Low Dispersion) element to combat longitudinal chromatic aberration—a common issue in macro photography where out-of-focus areas show color fringing. The lens is designed to produce high-contrast, razor-sharp results from the center to the extreme corners, ensuring that even the smallest details are captured with surgical precision. Performance is powered by a high-torque HSM (Hyper-Sonic Motor) that has been optimized for the mirrorless DG DN line, providing quiet and highly accurate autofocus. The lens is packed with professional features to streamline the macro workflow, including a Focus Range Limiter (with three settings to prevent "hunting"), a de-clickable aperture ring for video work, and an AFL button for custom functions. The lens is built for the field with a dust and splash-resistant structure and a water/oil-repellent coating on the front element. Unlike many older macro lenses, the internal focus design ensures the lens barrel does not extend during use, protecting your subject from accidental contact.
