The 45mm format is the closest approximation to human field of vision and captures high-resolution shots to an unparalleled degree of resolving power. Furthermore, the integration of VC into a 45mm fast standard prime lens for full-frame DSLR cameras is an industry-first*. Compose an image at will, without regard to shooting distance or ambient lighting constraints – to produce crisp, tack sharp images from F/1.8 full open aperture. The unique synthesis of a VC system in a 45mm lens with a best-in-class MOD of 0.29m** redefines standard distance shooting – freeing the photographer to discover another dimension of personal style. High Performance at F/1.8 Full Aperture 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. Closest Focusing Distance in its Class The SP 45mm (MOD: 0.29m) offers best-in-class close focusing*. A floating system design feature seamlessly optimizes image quality by shifting elements relative to the focus group in close shooting situations. * 45mm: Rated top among current 45mm and 50mm fixed focal length interchangeable AF lenses for full-frame DSLR cameras excluding macro lenses (As of July 2015.

VC (Vibration Compensation) Integration, Setting Itself Apart 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 high-pixel 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 full-frame format. Ultrasonic Silent Drive (USD) The USD actuator converts ultrasonic waves into rotational motion that delivers autofocus with responsiveness, accuracy, and speed without so much as a whisper. The photographer can easily use manual focus at any point while the AF system is operating without having to fumble for a switch. Molded Glass Aspherical Elements Two molded glass aspherical elements deliver planarity in field curvature. These elements ensure superb focusing uniformity over the entire field by compensating for spherical and comatic aberrations. LD (Low Dispersion) Glass To further compensate for chromatic aberrations, the new SP Series lenses use an LD element. This element helps to deliver crisp, clear images without color fringing. eBAND and BBAR Coating eBAND (Extended Bandwidth and Angular-Dependency) Coating and BBAR (Broad-Band Anti-Reflection) Coating both provide superior anti-reflection properties. These technologies have been adapted to each lens and provide crystal clear images by suppressing element surface reflections that lead to ghosting and flare. eBAND Coating is a nano-structured layer deployed on the critical element surface. In addition to regular anti-reflection coatings, eBAND Coating offers higher transmissivity and a significant improvement in anti-reflection characteristics against angulated incident rays. Circular Aperture Even when stopped down two steps, the nine-blade diaphragm maintains its circular shape to deliver nicely-tuned background blur.
