Designed to be an ultra-versatile single-lens option for “people photographers” in particular, the Tamron 35-150mm F2.8-4 Di VC OSD offers a semi-wide angle all the way through portrait and short telephoto focal lengths in a single, compact package. The lens has been designed with optical performance to satisfy the requirements of even the highest-resolution full frame sensors on the market today. It’s optimized around the 85mm range, which solidifies its designation as a “portrait zoom.” Despite the wide range, it is still only five inches (~125mm) long and weighs less than two pounds.
Superb optical performance meets requirements of high resolution 50+ megapixel DSLRs
Chromatic aberration and other imperfections that can diminish and degrade resolving power are thoroughly controlled by an optical design that combines three high-performance LD (Low Dispersion) glass elements with three hybrid aspherical lens elements aligned in perfect balance. The result provides the high levels of sharpness and contrast that today’s high-resolution digital cameras require. Tamron’s exclusive formula is optimized for exceptional performance around the mid-zoom 85mm range because that focal length has long been regarded as the preferred choice for portrait shooting. True to its designation as a “portrait zoom,” the Model A043 leverages Tamron’s optical technologies across the entire zoom range from wide-angle to telephoto to assure the finest experience at any setting. Making full use of the controlled depth-of-field properties only fast-aperture lenses can provide, Tamron employed proprietary simulation technologies to maximize the soft and natural “bokeh” defocused blur it has cultivated over many years. As a result, in-focus areas are rendered sharp and crisp down to the fine details which helps the subject stand out against a gently and beautifully blurred background. This technique is highly prized by portrait photographers and is potent for virtually every other type of photography.
Outstanding performance even in strongly backlit situations
Tamron’s legendary BBAR (Broad-Brand Anti-Reflection) Coating works in harmony with an optical design that suppresses internal lens reflections to significantly reduce all traces of ghosting and flare. Because portraits are often shot under backlight conditions for impact, Tamron uses these advanced technologies to preserve high image quality even when strong sources of light—including the sun—are in frame.
High-speed Dual MPU (Micro-Processing Unit) control system delivers fast and highly responsive autofocus performance plus outstanding vibration compensation
Silent autofocus driven by OSD (Optimized Silent Drive) DC motor
The OSD DC motor debuted in the 17-35mm F/2.8-4 Di OSD (Model A037) with favorable response. OSD technology reduces drive noise significantly (compared to previous DC motor-equipped lenses) while boosting autofocusing precision and speed by a wide margin. This eliminates noisy distractions during portrait shooting. Furthermore, the superior AF precision also provides more accurate tracking when locked on moving subjects.
Outstanding VC (Vibration Compensation)
Tamron’s original VC system is enhanced in the A043 with an independent MPU dedicated to image stabilization without detracting from AF processing functions. Consequently, the VC (Vibration Compensation) achieves 5 stops*, according to CIPA Standards. This is highly beneficial when shooting at the telephoto end where camera movement is magnified. It’s also very valuable when shooting at slow shutter speeds in dim lighting conditions.
MOD (Minimum Object Distance) of 0.45m (17.7 in) across the entire zoom range
Close focusing, the A043 delivers an MOD of 0.45m at all focal lengths thereby expanding versatility and creative freedom. This allows portrait photographers to get in close to capture expressions and smaller details and allows them to adjust camera-to-subject distance with greater control. Even when shooting indoors where movement is restricted, users can make use of this feature to find the perfect shooting position and angle.
Seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or rain to provide Moisture-Resistant Construction. This feature affords an additional layer of protection when shooting outdoors under adverse weather conditions.
The surface of the front element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The front surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture or oily fingerprints, allowing for much easier maintenance.
