The Voigtlander Ultron 40mm f/2.0 SL-II Manual Focus Lens is an ultra-compact, sturdy manual focus lens that features high-quality traditional construction with classic styling, while using modern optical lens technology. This lens is part of the SL II series, which feature a CPU (Central Processing Unit) built into the lens. Having the CPU integrated into the lens allows it to support the camera's metering functions, even with the latest DSLRs (in manual focus). In addition, this also means that the aperture is now controlled by the camera's command dial.
This lens offers a bright f/2 maximum aperture, with a minimum focusing distance of 1.25' (38cm), and a maximum magnification ratio of 1:7. However, this lens is supplied with a dedicated close-up lens, which results in a minimum focusing distance of 0.8' (25cm), and a maximum magnification ratio of 1:4. Used on an APS-C sized DSLR camera, this lens is equivalent to a 60mm lens in 35mm terms.
