Venus - Optics Laowa Aksen 17.5mm f/1.7 5-10x Ultra Macro APO Lens (Sony E) - Black

The Laowa Aksen 17.5mm f/1.7 5-10x Ultra Macro APO lens from Venus Optics is built for full-frame Sony E-mount cameras and offers a magnification range of 5:1 to 10:1, allowing subjects to be captured larger than life. The lens has an aperture range of f/1.7 to f/5.6 and uses an 11-blade diaphragm. A fixed working distance of 0.9 inches is maintained from the front of the lens throughout the zoom range. The internal parfocal zoom design keeps focus consistent as magnification is adjusted, without needing to reposition the camera or subject. This helps when working with lighting setups or focus stacking, since the working distance and framing stay stable during magnification changes. The optical design uses 17 elements in 12 groups with apochromatic correction, intended to reduce color fringing at higher magnification levels.
