Tamron SP 45mm f/1.8 Di VC USD Lens for Canon EF

Slightly wider than the venerable 50mm standard focal length, the Canon EF 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. A normal-length prime, this 45mm lens is designed for full-frame Canon EF mount DSLRs, and is also compatible with APS-C models where it will provide a 72mm equivalent focal length. Fast f/1.8 maximum aperture benefits working in low-light conditions and also avails selective focus control. One LD (Low Dispersion) element helps to minimize chromatic aberrations in order to achieve greater clarity with reduced color fringing. 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.
