The Nikon F mount SP 45mm f/1.8 Di VC USD from Tamron presents a unique perspective and pairs it with a sophisticated optical layout and VC image stabilization for enhanced image quality. One Low Dispersion element and two aspherical elements help to control a variety of aberrations and distortions for consistent and even illumination and sharpness, as well as reduced color fringing, and eBAND and BBAR coatings work to suppress flare and ghosting for increased contrast and color fidelity. An inner focusing design and Floating System are also used, and aid in achieving a minimum focusing distance of 11.4" with a maximum magnification of 1:3.4. Fast f/1.8 maximum aperture benefits working in low-light conditions and also avails selective focus control. Two aspherical elements correct for spherical and comatic aberrations, as well as distortion, for consistent edge-to-edge sharpness and illumination throughout the aperture range, as well as a reduction of sagittal comatic flare. Additionally, a fluorine coating has been applied to the front lens element to repel water, fingerprints, and smudges for easier cleaning of the lens surface. A Floating System is employed that moves a single group of elements to control focus in order to provide faster AF response as well as a minimum focusing distance of 11.4" and a maximum magnification ratio of 1:3.4 for enhanced close-up shooting.
