Venus - Optics Laowa Aksen 45mm f/2.8 1-5x Ultra Macro APO Lens (Sony E) - Black

The Laowa Aksen 45mm f/2.8 1-5X Ultra Macro APO Lens for Sony E mount is a full-frame macro lens offering 1:1 to 5:1 magnification for extreme close-up photography. Its apochromatic (APO) optical design, built from 13 elements in 9 groups, is engineered to reduce chromatic aberration and color fringing across the magnification range. An internal parfocal zoom mechanism allows magnification to be adjusted without disturbing focus, camera position, or lighting setup, making the lens suited to both handheld stills work and motorized focus stacking. The lens maintains a fixed working distance of approximately 1.6 inches (40.35mm) from the front element to the subject. Aperture ranges from f/2.8 to f/11, controlled by an 11-blade diaphragm. This is a manual, fixed-focus lens: focus is achieved by adjusting the distance between the camera and the subject rather than through a traditional focus ring. The compact, lightweight housing (2.8 x 4.8", 599g) is designed for handheld shooting as well as mounting on focus rail or focus-stacking rigs.
