|Tamron SP AF 10-24mm wide-angle zoom lens
Tamron SP AF 10-24mm F/3.5-4.5 Di II LD Aspherical (IF) lens : Mr. Morio Ono, President of Tamron Co., Ltd., announced the development of the SP AF10-24mm F/3.5-4.5 Di II LD Aspherical (IF) (Model AB001), a new high performance ultra wide-angle zoom lens designed exclusively for digital SLR cameras with APS-C size imagers. Di II (Digitally-Integrated design) lenses are designed for exclusive use on digital cameras with smaller-size imagers. The new SP AF 10-24mm F/3.5-4.5 Di II LD Aspherical (IF) is an advanced ultra wide-angle zoom lens that is versatile and offers even higher performance and specifications than the current Tamron SP AF 11-18mm F/4.5-5.6 zoom lens. |
Tamron SP AF 10-24mm wide-angle zoom lens
The lens covers an extended focal length range that is particularly wide for an ultra wide-angle zoom lens, while improving the aperture to F/3.5-4.5 and keeping the filter diameter to 77mm. Its lightweight and compact size makes this new wide-angle zoom very user friendly. The lens was designed for use with digital SLR cameras and thereby employs special optical glass materials for outstanding optical performance such as large-aperture glass-molded aspherical elements and hybrid aspherical elements.
Tamron AF 10-24mm lens - Focal length & Zoom
The new Tamron zoom covers a focal length range equivalent to 16-37mm when converted to a 35mm full-size format. Its ultra-wide zoom ratio of more than 2X provides a versatile variety of angles of view, thus improving photographic creativity.
Tamron 10-24mm lens - Special optical glass elements
The new zoom lens uses an HID glass element and a pair of LD glass elements to minimize on-axis and lateral chromatic aberrations that are the greatest hindrance to high optical quality. To further achieve outstanding optical quality, the lens uses a high quality, glass-molded aspherical element and three hybrid aspherical elements to thoroughly compensate for spherical and chromatic aberrations and distortion.
Tamron SP AF 10-24mm Di II LD lens - Optical system
The ultra wide zoom lens uses a new optical system designed to confine the changing angles of incidences of light rays reaching the imager within a certain scope over the entire image field from the center to the periphery, by considering the effects of variances due to zooming. Peripheral light fall-off is minimized, resulting in high quality images from the center to the periphery. The SP Di II class lens provides high optical quality in terms of resolution, contrast and flatness of image field.
Tamron 10-24mm F/3.5-4.5 Aspherical lens - Internal Surface Coating
The lens uses a newly developed multiple coating and internal surface coating, (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.
Tamron AF 10-24mm Di II lens - Ultra compact & Lightweight design
The new zoom lens covers a wider focal length range with a greater zoom ratio and offers a faster maximum aperture and enhanced optical quality than the existing SP AF11-18mm zoom lens. Despite higher specifications that are likely to incur a bulky design, the new zoom lens is lightweight and compact. Tamron has successfully realized a versatile ultra wide-angle zoom lens that is lightweight and compact enough in overall length and diameter to accept a 77mm filter, the same as the existing SP AF11-18mm zoom lens.
Tamron F/3.5-4.5 Di II LD Aspherical (IF) lens - Focus distance
Considering the importance of “close focusing capability” as an essential condition in wide-angle photography, Tamron has achieved a 0.24m minimum focus distance over the entire zoom range. Getting closer to the subject allows you to easily express a more creative photographic vision.
Tamron 10-24mm lens - Flower-shaped lens hood
A glare-reducing flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of superfluous light rays that enter from the rectangular frame outside the image field.
Tamron wide angle zoom lens - External design
The external design is improved to enhance the uniformity and smoothness. The metallic finish of the gold band of Tamron lenses makes it stand out as a Di II lens, while the layout of alphanumerical markings is improved for better visibility. The rubber patterns of the zoom and focus rings have also been improved to compliment today’s digital camera design style and to provide better handling.
