Macro/portrait lens with internal focusing. Image sensor standard: full frame. Lens mount: Sony E-Mount. Focus: manual. Filter thread diameter: 67 mm. 13 aperture blades provide an impressive and pleasing bokeh. The internal focusing prevents collision with the subject and reduces the risk of dust entering the lens. More than just a macro lens. The ability to focus infinitely, the 58mm focal length (40.9° AoV), and the aperture of f/2.8 make this lens suitable not only for macro photography but also for portraits, product photography, or as a "walk-around" lens. No chromatic aberration. The lens is designed to suppress both longitudinal and lateral chromatic aberration in both in-focus and out-of-focus areas. Purple fringing and ghosting are minimized across the entire aperture range. The APO construction significantly reduces post-processing time, especially for macro shots. Razor-sharp images. The lens is specifically designed for mirrorless systems and features 3 ED elements and 3 elements with ultra-high refractive index. With a shorter flange distance, it not only enhances image sharpness but also makes the lens more compact.
