Tamron Develops SP AF60mm F/2.0 Di II MACRO 1:1

Tamron Co., Ltd (Mr. Morio Ono, President), a comprehensive manufacturer of optical products with its head office in Saitama City, announced the development of the SP AF60mm F/2.0 Di II LD (IF) MACRO 1:1 (Model G005), 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 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(*1) 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.

   


DEVELOPMENT CONCEPT
Tamron's macro lenses (SP AF90mm F/2.8 Di MACRO 1:1 (Model 272E), SP AF180mm F/3.5 Di MACRO 1:1 (Model B01) are world renowned for their outstanding optical performance. Particularly, the Tamron SP AF90mm macro lens first introduced in 1979 and subsequently upgraded and renewed seven times since has been highly evaluated by many photographers as a lens that delivers not only attractive out-of-focus effects and sharp descriptive performance in macro photography with its easy-to-use focal length, but also as a lens ideal for portraiture.

Amid the growing popularity of APS-C size DSLRs, Tamron recognizes that there are many photographers who wish to enjoy macro photography with a focal length that provides an angle of view equivalent to 90mm. Tamron therefore developed the SP AF60mm medium telephoto macro lens to meet the desire of those users and goes a step further by providing the extremely fast and desirable maximum aperture of F/2.0. The SP AF60mm is a high performance and versatile lens that is suitable not only for macro photography of textiles, small creatures, flora and more, but also for portraiture by making good use of its easy-to-use focal length, fast maximum aperture and high optical quality even in low-lit conditions.

OPTICAL FEATURES

1. 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 (14.1oz.).
2. Internal focusing system for enhanced ease of useThe 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(*4). 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.  
3. Full-time manual control mechanism.Delicate focusing 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 switch-over button, even when in the auto-focus mode. In addition, the lens employs a large focus control ring to ensure a solid grip and precise control when manually focusing.
4. 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.
