SUMMARY
Laowa has released the Aksen 17.5mm and 45mm Ultra Macro APO zoom lenses, designed for extreme close-up photography and videography, offering magnifications from 1x to 10x. These lenses feature a parfocal design, meaning focus is maintained throughout the zoom range, and have fixed working distances (approximately 22mm for the 17.5mm and 40mm for the 45mm). Users adjust focus by moving the camera relative to the subject, and the internal zooming mechanism prevents the lens barrel from extending. The 17.5mm lens includes compatibility for a coaxial light to illuminate subjects without casting shadows. Both lenses are lightweight, internally zooming, APO-designed to minimize chromatic aberration, and available in multiple mount options.
