The integration of VC (Vibration Compensation) into a fast standard prime lensPRIME LENSA photographic lens used as an (1) alternative, fixed focal length alternative to a zoom lens or, (2) more traditionally, as the primary lens in a combination lens system. In the first sense, a prime lens is known for having a larger maximum aperture and consequently offers greater shutter speeds, having advanced optics and weighing less than zoom lenses, albeit less flexible, because of their simpler construction with less moving parts. In the second sense, a prime lens refers to the primary lens when paired with other optical devices. A prime lens's focal length is fixed and the photographer is required to move closer or further to achieve the correct image composition. for full-frame DSLR cameras now optimises 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 apertureAPERTUREAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Aperture refers to an opening inside the lens, similar to the iris of your eye, that changes in diameter to control the amount of light that enters a camera. Aperture is expressed in f-stops: the lower the number, the larger the aperture, e.g. f/1.4 is larger than f/8. A larger (or wider) aperture allows more light to pass through the lens to the sensor (film) as a picture is taken, particularly useful in low-light conditions. A larger aperture also produces a shallower depth-of-field, and thus more background blur..
High Performance at F/1.8 Full Aperture
The open aperture is set to F/1.8 with optimised 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 materialised 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 optimises image quality by shifting elements relative to the focus group in close shooting situations.
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-pixelPIXELThe shortening of 'picture element', a basic unit of programmable colour forming the dots that make up an image. Pixel size depends on a camera’s resolution, which is measured in megapixels (MP), meaning millions of pixels. The more pixels on a sensor, the smaller they have to be to fit. An image's number (or density) of pixels correlate to the amount of information and image holds. Cameras with more pixels on the sensor have a higher pixel density and thus more resolving power, able to capture smaller details with much more clarity and accuracy. Higher resolution images can be cropped more agressively and also produce better quality large prints. 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.
Moulded Glass Aspherical Elements
Two moulded 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 flareFLAREOccurs when a point light source such as the sun or an artificial light (that is brighter than the rest of the scene), hits the front element of a lens resulting in a lack of contrast, haze, or unwanted semi-transparent objects being present in the image. You can avoid lens flare with a lenshood or filters, however, the effect is also useful for bringing artistic elements into an image, such as sun rays peaking out from behind a rock formation. .
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 45mm lens delivers exceptionally uniform illumination levels across the image field to avoid non-linear pattern or fall-off toward corners.
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.
