Life-size macro lens designed exclusively for digital SLR cameras with APS-C size image sensors* that features a fast maximum aperture of F/2
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.
Notes
* Tamron’s conversion value is 1.55x.
* Di II lenses are designed exclusively for use with digital SLR cameras equipped with APS-C size image sensors and employ an optical system optimised for the characteristics of those digital cameras. Di II lenses are not designed for use with 35mm film cameras or digital SLR cameras with image sensors larger than 24mm x 16mm.
* The special note “APS-C size equivalent” is hereinafter omitted.
OPTICAL FEATURES 1. 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 realises 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. Developed with Tamron’s extensive macro lens design know-how, the attractive SP AF60mm finely balances sharp image performance with beautiful out-of-focus background effects.
2. 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.
3. Working distance of 100mm, the longest distance among lenses in this class**
Tamron has realised 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.
4. Meticulous countermeasures against ghosting & flare
Tamron has employed new BBAR (Broad-Band Anti-Reflection) multi-layer coatings in order to ensure optimum performance in all photographic situations. The new BBAR coatings enhance the light transmission factors in both the short and long wavelength ranges, a condition that was thought incompatible with conventional anti-reflection coating technology. In addition, Tamron employs internal surface coatings (coatings on cemented surfaces of lens elements) for sharpness, high colour reproduction performance and superior colour balance.
MECHANICAL FEATURES 1. Fast F/2.0 maximum aperture in a lightweight, compact macro lens
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 and reliability of precision components. Precision injection-molded plastic engineering has allowed a compact body with a maximum diameter of only 73mm (2.9") and weighing a mere 400g (14.1oz).
2. Internal focusing system for enhanced ease of use
The lens employs an internal focusing (IF) system which preserves the overall length of the lens due while focusing. As the front group of the lens does not extend, the lens is particularly easy to use in close focusing ranges.
3. Long working distance
The working distance of 100mm of this lens is the longest among lenses in its class**. The IF system and other new optical solutions that contribute to this longer working distance allows the user to maintain a good working distance from tiny subjects.
4. Full-time manual control mechanism
Fine focus control is essential in macro photography. The lens incorporates a full-time manual control mechanism that enables the user to manually adjust focus without engaging the AF/MF switchover button, even when in the autofocus mode. The large focus control ring ensures a solid grip and precise control of manual focusing.
5. Simple, attractive outer design
The lens employs a new outer design that is more refined and smoother in its overall contours by minimising concavity, convexity and variations in its profile to match various digital SLR cameras. The delicate matte finish on the lens barrel enhances the high-quality appearance of the lens.
