For the first time, a dedicated portrait lens that allows you to zoom through various composition options as the creative ideas zoom through your head. The 35-150mm F/2.8-4 Di VC OSD (Model A043) zoom lens is based on the new concept of allowing you to concentrate on a wide range of portrait compositions without the interruption of pausing to change lenses. The fast F-stop offers F/2.8 at the wide end while maintaining a bright F/4 at the telephoto end. High quality, flexibility and broad creative expression—you can have them all with Tamron’s new portrait zoom lens. Extends Photographic Expression Express your creativity as a portrait photographer by pursuing every dimension from dramatic close-up expressions to delicate movements. This lens is designed to let you enjoy portrait shooting as you intend. The A043 offers a zoom ratio of nearly 4.3x, with focal lengths ranging from 35mm at the wide end to 150mm at the telephoto end. And if a more structured approach better suits you, you’ll find scale markers that indicate the popular focal length settings for portrait photography (ref. right animation). The versatile zoom range incorporates the 85mm focal length (often regarded as optimum for portrait shooting) and covers everything from full-body shots that include the surrounding area to sharp head-and-shoulders shots. Make the most of every moment. High Resolution and Brilliant Bokeh The A043 features a specialized optical formula that employs three LD (Low Dispersion) and three hybrid aspherical lens elements to thoroughly control optical aberrations. Tamron’s proprietary anti-reflecting BBAR (Broad-Band Anti-Reflection) Coating significantly reduces ghosting and flare that might otherwise occur under backlight conditions, where portraits are often shot. The result provides the advanced levels of sharpness and contrast that today’s high resolution 50+ megapixel DSLRs require. Tamron has also balanced MTF performance to produce exceptional resolving power across the entire zoom range and deliver premium optical performance. Furthermore, Tamron has combined its expertise in producing soft, beautiful bokeh defocus blur with the latest simulation technologies. As a result, the contrast between in-focus areas rendered accurately down to the fine details and backgrounds that gently blend into the scene produces a single high quality image. Enjoy this inspired performance for portraits, landscapes, travel, family snapshots and more across a wide range of subjects. Crisp, Sharp Images The A043 includes Tamron’s exclusive Dual MPU system: a dedicated micro-processing unit for vibration compensation, and separate microprocessor for lens system control, including AF. Each MPU has a DSP (Digital Signal Processing) block for high speed signal processing that combines reliable vibration compensation with exceptional AF performance. The result effectively reduces focus deviations and camera shake and is especially valuable in low-light conditions. Close-Up Composition In addition to a wide range of focal lengths, the A043 provides an MOD of 0.45m (17.7 in) across the entire zoom range. This allows you to approach the subject close-up even when shooting at the telephoto end, which adds new possibilities to portrait composition. By varying the distance between you and the subject, you can intensify close communication with the subject, a crucial aspect of portrait photography. Even when shooting indoors where movement is restricted, you will be able to find just the right shooting position and angle. Experience the rich variation in the world of close-up photography of eyes, skin texture and other points of focus that becomes possible as you move nearer to the subject.
