SP 45mm F/1.8 Di VC USD
<b>Get Closer than Ever Before</b>
Move in closer to subjects with the new Tamron lenses. New MOD specs let photographers shoot at close range, opening a new world of creative opportunities for composition while maintaining image quality.
<b>Innovative and Unique Standard Lenses with F/1.8 Fast Aperture</b>
State-of-the-art design and engineering technologies backed by manufacturing know-how culminate in revolutionary 35mm and 45mm lenses.
<b>High Performance at F/1.8 Full Aperture</b>
The open aperture is set to F/1.8 with optimized critical properties at a higher level: superb optical performance coupled with a VC system, a shorter MOD, and a well-balanced form factor. Rigorous simulation processes performed throughout the design phase are materialized in distinguished resolving power and beautifully-tuned background blur, a prominent feature to a fast-aperture, full-frame compliant optic.
<b>VC (Vibration Compensation) Integration, Setting Itself Apart</b>
VC deployed on fast-aperture lenses dramatically enhances freedom of hand-held shooting under lime light or dim room light conditions by eliminating minute camera shake. In particular, cameras with highpixel density imagers tend to pick up subtle vibrations, resulting in degradation of image quality. VC is an excellent attribute to acquire inherent high-fidelity images. 45mm is the very first lens that employs the VC functionality among the fast standard fixed focal lenses in fullframe format.
