High quality, flexibility and broad creative expression
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. The compact Model A043 is designed for easy carrying, measuring only 124.3mm (4.9 in) long and weighing just 790g (27.9 oz). For fast and steady operation, this exciting zoom incorporates Tamron’s Dual MPU (Micro-Processing Unit) system, which strikes the perfect balance between AF performance and effective vibration compensation. Additionally, optical performance tuned to accentuate the finest qualities of the subject combines clear image quality and soft bokeh defocus blur at the highest level. For greater flexibility when used outdoors, Moisture-Resistant Construction and a Fluorine Coating deliver extra measures of protection. Also, the BBAR (Broad-Band Anti-Reflection) Coating effectively reduces ghosting and flare as well. High quality, flexibility and broad creative expression—you can have them all with Tamron’s new portrait zoom lens.
Express your creativity as a portrait photographer by pursuing every dimension from dramatic close-up expressions to delicate movements. We want you to enjoy portrait shooting as you intend, and that is the sentiment we poured into this lens. The Model 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. With this single lens you can make the most of every moment you spend with any subject.
The Model 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 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 many years of 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 excellent, inspired performance for portraits, landscapes, travel, family snapshots and more across a wide range of photography subjects.
The Model 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.
AF with Optimized Silent Drive quietly tracks constantly moving subjects with ease
The AF drive employs a newly developed OSD (Optimized Silent Drive) to ensure silent operation. Operating noise has been appreciably reduced thanks to a revamped and optimized AF unit.
Photographers and subjects can converse and enjoy the mood of the moment while devoting their efforts to portrait shooting without noisy intermittent distractions. Also, the precision and speed of autofocusing are increased to ensure accurate focus even when tracking constantly moving subjects.
VC (Vibration Compensation) counteracts camera shake and expands opportunities
The Model A043 is equipped with Tamron’s legendary VC that achieves compensation equivalent to 5 stops* (CIPA standards) to effectively reduce the effects of camera shake. This is particularly beneficial when shooting at the shake-prone telephoto end and when shooting at slower shutter speeds. VC ensures that subjects will be faithfully captured down to the fine details even when shooting in low-light environments, such as twilight or indoors, without flash.
* CIPA Standard Compliant. For Canon: EOS-5D MKIII is used. For Nikon: D810 is used.
In addition to a wide range of focal lengths, the Model 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.
Using the Model A043 as a set with Tamron’s 17-35mm F/2.8-4 Di OSD (Model A037) ultrawide-angle zoom supports an amazingly broad range of shooting styles from landscape and street photography to architecture and portrait photography—and everything in between! What’s more, the lenses have a combined weight of just 1,250g (44.1 oz)*, making them the perfect combo when you want to travel light.

Optical Construction (19 elements in 14 groups)
MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.
The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.
Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.
Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance.
