Tamron SP AF 10-24mm F3.5-4.5 DI II LD Aspherical (IF) Lens

The Tamron 10-24mm is the first-ever tamron lens that has 0.24m (9.4") Minimum Focus Distance, the perfect tool for creating dramatic landscape, cityscape, and seascape imagery. At the ultra wide-angle setting, you'll be able to capture vistas beyond what the eye can see. At the semi-wide-angle setting, you'll capture scenes with angles of view almost as spectacular. The precision mechanical component IF (Internal Focus) is coordinated to the multiple cam mechanism to ensure seamless and accurate positioning. With ø77 Filter Diameter and F/3.5-4.5 aperture accompanied by Hybrid Aspherical Elements, it lessens lateral and on-axis chromatic aberrations resulting to quality images. Combined with its Low Dispersion (LD) glass and 12 elements in 9 groups, sharpness is made possible by refracting rays of light adding up more vivid outcome. It is compatible only with APS-C DSLR Cameras.

Product Features in Detail

Tamron Di-II lenses
Engineered expressly for digital SLR cameras* with image sensors commonly referred to as APS-C, measuring approximately 24mm x 16mm. Rendering an ideal image circle for APS-C sensors, Di-II lenses are also include properties to optimize digital imaging performance.

Low Dispersion (LD) Glass for Greater Lens Sharpness
Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)

Hybrid Aspherical Elements Provide the Ultimate in Image Quality and Compactness
Tamron uses several hybrid aspherical lens elements in many lenses bearing the Aspherical designation. These innovative optics allow us to achieve the ultimate in image quality, and at the same time produce lenses that offer remarkable zoom ranges in extraordinarily compact packages. By perfecting theses cutting-edge advances for series production, Tamron has advanced the state of optical design, and virtually eliminated spherical aberration and image distortion from the high-power-zoom series.Through the effective application of Hybrid Aspherical Technology, one lens elemen tcan take the place of multiple elements without compromising performance. This is what allows us to produce remarkably compact long-range lenses that deliver a uniformly high level of image quality at all focal lengths and apertures.

Internal Focusing (IF) System
Internal focusing (IF) provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron’s Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions.

Performance takes priority for superb image quality
This line of ultra-high-performance lenses is designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. The foremost priority is achieving superior performance parameters – high design standards take priority over cost constraints. As a result, Tamron SP lenses feature innovative designs that have established an enviable reputation for excellence amongst demanding photographers.

Minimises chromatic aberrations
The use of HID glass elements in a lens minimises on-axis and lateral chromatic aberrations that are the greatest hindrances to achieving high image quality. HID glass has allowed Tamron to produce complex lenses such as long-range zooms that are conveniently compact and lightweight while delivering outstanding performance.

Sharpens edges by reducing 'colour fringing'
Chromatic aberration occurs when a lens element refracts different wavelengths of a ray of light – its rainbow colours – at very slightly different angles. This results in the 'colour fringing' that reduces the sharpness of an image. LD elements are made from special glass materials with extremely low dispersion indices (i.e. the refraction of a ray of light into rainbow colours is extremely narrow). Thus they effectively compensate for chromatic aberration at the centre of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (toward the edges of the field) that often occurs at short (wideangle) focal lengths.

Special glass for high optical performance
The new zoom lens uses a high-precision, large-aperture glass-moulded aspherical lens element and three hybrid aspherical elements to minimise spherical aberration, coma, and distortion. In addition, a pair of LD (Low Dispersion) glass elements and an HID (High Index high Dispersion) glass element together compensate for on-axis and lateral chromatic aberrations, delivering high optical quality.

Optimal angles of incidence of light at the imaging sensor
The new ultra wide-angle zoom lens uses a new optical system designed to confine the changing angles of incidences of light rays reaching the imaging sensor within a certain scope over the entire image field, from the centre to the periphery, addressing the effects of variances caused by zooming.

Internal surface coatings reduce ghosting and flare
The lens uses newly developed multiple-layer coatings and internal surface coatings (i.e., multiple-layer coatings on cemented surfaces of plural lenses) to reduce the image degradation caused by the reflection of light rays entering from the lens front and affected by the imager.

Covers the broadest range ever – from 10mm ultra wide-angle to 24mm – in its class
The new Tamron ultra wide-angle zoom lens covers the 35mm full-size format equivalent of 16-37mm, for the first time in this class of zoom lenses. This focal length range – 10mm ultra wide-angle to 24mm semi wide-angle – enables the user to enjoy hassle-free wide-angle photography.
