Tamron SP 45mm f/1.8 VC Lens for NikonThe 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.
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.
- Close Focusing Distance
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 Control
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.
- Ultrasonic Silent Drive
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 Aespherical 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 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.
- Fluorine Coating
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.
- Moisture Resistant Coating
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.
- Circular Aperture
Even when stopped down two steps, the nine-blade diaphragm maintains its circular shape to deliver nicely-tuned background blur.
