Delivering true 1:1 reproduction with edge-to-edge sharpness, its optical formula includes one ED and two aspherical elements alongside Nano Crystal Coat to suppress flare and chromatic aberration. The internal focusing design and silent wave motor provide fast, quiet autofocus without a rotating front element, making filter use straightforward. This lens is best for Nikon DSLR shooters who need a precise, lightweight macro lens for detailed close-up work and copy stand reproduction.
