Serial number 11602. This is the current model of the Noctilux lens, which is the brightest camera lens in the world. It features a configuration of 5 groups and 8 elements, with two of the surfaces incorporating non-spherical glass. Despite its extremely shallow depth of field at f/0.95, the lens produces stunning imagery with well-focused subject planes and minimal distortion. The built-in hood is now made of metal, enhancing its quality. Included in the package are the original box, genuine front and rear caps, a dedicated soft case, and documentation such as the warranty (expired) and manual. This is a domestic authorized product. There is slight paint loss on the tip of the built-in hood, a minor ding on the side of the hood, and some minor wear on the edges of the hood and helicoid, indicating light usage. However, the overall appearance is still clean. This lens would be suitable for those who want to enjoy shooting with the Noctilux 0.95 without hesitation. The glass is clear without any haze or wiping marks. All functions operate normally. This lens maintains rangefinder coupling reliably from the minimum focusing distance to infinity even when shooting wide open. While some lenses may exhibit a tendency towards back focusing from midway, this lens does not have that issue.
