Tamron has announced the availability of the its 60mm F/2 Di macro lens in Sony mount, to join the Canon and Nikon versions which are already shipping. It is a life-size macro lens designed exclusively for digital SLR cameras with APS-C size image sensors that offers a fast maximum aperture of F/2.0. The new lens is made available in mounts for Canon, Nikon (with built-in AF motor) and Sony.
The SP AF60mm F/2.0 Di II LD (IF) MACRO 1:1 (Model G005), covering an equivalent angle of view of 93mm when converted to the 35mm format and boasting a maximum aperture of F/2.0-one stop faster than the F/2.8 maximum aperture found on conventional macro lenses in the same class-is a fast life-size macro lens that delivers dramatically attractive blurred background effects.
Macro lenses are interchangeable lenses that have been specially designed for close-up photography. With a macro lens, even a small object can be photographed at a size that fills the whole image area. Macro lenses can be used for nature photography, such as plants and insects. They can also be used for close-up photography of familiar items such as jewelry and other small objects. In addition to its close-up capabilities, the new Tamron SP AF60mm F/2 Di II MACRO 1:1 can also be used for portrait photography, making good use of the attractive blurred background that is a feature of the fast F/2.0 maximum aperture lens. The lens also excels in situations where light is low, such as indoors or at dusk. All in all, this is a high performance lens that can be put to good use in a wide variety of situations.
Medium telephoto 1:1 life-size macro lens featuring a fast maximum aperture of F/2.0 that strikes a fine balance between attractive out-of-focus effects and sharpness: The SP AF60mm is a medium telephoto macro lens designed for APS-C size digital SLR cameras that realizes the fast maximum aperture of F/2.0 for the first time in the world. Using an optical design approach that attaches methodical importance to optical quality, Tamron’s optical designers have successfully controlled complex movements of respective lens groups in order to restrain the increase in aberration changes due to the fast maximum aperture, thus achieving outstanding depictive performance that is uniformly sharp from the center to the periphery. Since the maximum aperture of F/2.0 provides a depth-of-field that is shallower than that of conventional F/2.8 lenses, the new lens enables the user to expand the range of the macro photographic expression. The SP AF60mm developed by combining Tamron’s accumulated macro lens design know-how is an attractive lens that maintains a well-balanced relationship between sharp image performance and beautiful out-of-focus background effects.
Employment of special low-dispersion glass elements: The lens employs two large LD (low dispersion) glass elements in its first group to thoroughly compensate for various aberrations and attain high optical quality.
Working distance of 100mm, the longest distance among lenses in this class: Tamron has realized the long working distance of 100mm from the front element of the lens to the subject in 1:1 life-size macro photography. The long working distance allows the user to take macro shots while maintaining a sufficient distance from such subjects like timid insects that are likely to escape if you move in too close. Also, with this longer working distance, you can prevent capturing the shadow of the lens barrel as is often the case with conventional macro lenses with insufficient working distances.
Lightweight and compact macro lens boasts F/2.0 fast maximum aperture: In order to prevent the lens from becoming bulky due to the fast F/2.0 maximum aperture, Tamron’s mechanical engineers thoroughly reviewed the internal constructions of conventional macro lenses and improved the accuracy of precision components by combining Tamron’s accumulated mechanical engineering techniques. Through the employment of precision injection-molded engineering plastic parts with high reliability, Tamron realized a compact body that measures only 73mm (2.9in.) in its maximum diameter and weighs a mere 400g.
Internal focusing system for enhanced ease of use: The lens employs an internal focusing (IF) system without changing the overall length of the lens due to focusing. Since the front group of the lens does not extend, the lens is particularly easy to use in close focusing ranges. Tamron has realized the working distance of 100mm, the longest distance among lenses in this class. The internal focusing system combined with new optical solutions to realize this longer working distance allows the user to enjoy macro photography comfortably while maintaining an adequate distance from subjects.
Full-time manual control mechanism: The lens incorporates a full-time manual control mechanism that enables the user to manually adjust focus without engaging the AF/MF switch-over button, even when in the auto-focus mode.
Simple and attractive outer design: The lens employs a new outer design that is more refined and smoother in its overall contours by minimizing concavity, convexity and variations in its profile to match various digital SLR cameras. The lens barrel features a delicate matte finish, which enhances the high quality appearance of the lens.
The lens will start shipping from October 2009.
