作为非全副相机的标准变焦镜头，腾龙 28-75/2.8 一直以其暖色调的风格为大家所推崇。最近它进行了升级，推出最新的尼康卡口镜身马达版，以适应 Nikon D40，D40X 和 D60 机身。在这些相机中焦段将变成 42-112.5mm（折换成 全副35mm 格式）。全程最近对焦距离为 33cm，因此冠上了微距的名号。

特点：
1，更轻的重量
2，最近对焦距离 0.33 m
3，改进机械设计，在最小化变焦扭矩的同时，缩小最大直径
4，变焦锁
5，莲花遮光罩
6，新一代镜头的良好外形和质感

Tamron has continued its process of adding in-lens motors to its Nikon-mount lenses, with its 28-75mm f/2.8 being the latest recipient. This makes the lens fully compatible with the Nikon D40, D40x and D60, offering their owners fields of view equivalent to a 42-112.5mm lens (in FX/35mm terms). The magnificently named ‘SP AF28-75mm F/2.8 XR Di LD Aspherical (IF) MACRO’ can focus as close as 33cm throughout its zoom range.

* Lightweight, fast standard zoom lens featuring Tamron’s proprietary XR technology
* Minimum focus distance of 0.33m over the entire zoom range for 1:3.9 maximum magnification
* Mechanical design improvements for downsizing the maximum diameter while minimizing changes in zooming torque
* Zoom lock mechanism for convenience in carrying the outfit
* Flower-shaped lens hood as a standard accessory
* Form and texture appealing “high performance and the feel of high accuracy” worthy for the name “SP” – Outer design matching the new generation lens
