SP 45mm f/1.8 Di VC USD - Canon EF Fit

The Tamron SP 45mm f/1.8 Di VC USD is a prime lens designed for Canon EF mount cameras, offering a moderate wide-angle perspective slightly broader than a standard 50mm focal length. This lens combines optical sophistication with practical features, including a fast f/1.8 maximum aperture that enables low-light performance and selective focus control, along with vibration compensation for sharper handheld shooting. The optical design incorporates one Low Dispersion element and two aspherical elements to minimize chromatic aberrations and distortions while maintaining consistent sharpness across the frame, while eBAND and BBAR coatings reduce flare and ghosting for improved contrast and color accuracy.

The lens features a ring-type USD motor for fast and quiet autofocus with full-time manual focus capability, and employs an inner focusing design and floating system to achieve a minimum focusing distance of 11.4 inches with a maximum magnification ratio of 1:3.4. Construction includes moisture-resistant seals and a fluorine-coated front element for protection against environmental elements and easier maintenance, making it suitable for a variety of shooting conditions.
