The integration of VC (Vibration Compensation) into a fast standard prime lens for full-frame DSLR cameras now optimizes the potential of the 45mm lens to a degree of resolving power never seen before — to capture crisp and tack sharp images at any setting from F/1.8 full open aperture.
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.

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.
Even when stopped down two steps, the nine-blade diaphragm maintains its circular shape to deliver nicely-tuned background blur.
Optimal Relative Illumination
The 35mm lens delivers exceptionally uniform illumination levels across the image field to avoid non-linear pattern or fall-off toward corners.
Fluorine Coating and Moisture-Resistant Construction
Developed for industrial optics, fluorine coating offers long-lasting oil and water resistance to the lens. Moisture and smudges wipe away, making it easy to keep your lens clean.
Constructed to prevent moisture from entering the internal mechanisms of the lens, the new SP line is sealed to allow photographers to shoot outdoors in adverse conditions.
