Slightly wider than the venerable 50mm standard focal length, 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.

Complementing the imaging capabilities, this 45mm f/1.8 lens is also characterized by a ring-type USD motor, which provides quick, quiet autofocus performance with full-time manual focus capabilities. 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. The lens' construction is also notable in its inclusion of various seals to protect against moisture, as well as a fluorine-coated front element to guard against fingerprints, smudging, and water.
