A New Chapter in the Distinguished History of Tamron’s 90mm Macro Lenses
A Legacy of Superior Optical Performance Now Reaches a New Plateau with Enhanced VC Functionality and Advanced Features
The SP 90mm F/2.8 MACRO VC (Model F017) is the most recent release in a successful line of Tamron SP 90mm macro lenses. It redefines the best in advanced features and succeeds a legacy of superior optical performance.
XY-Shift compensation has been newly added to reinforce VC functionality, further improving image stabilization capabilities at any shooting distance from infinity to macro. Advancements in USD control software have also increased AF focusing speed and optimally fine-tuned for various framing conditions. Furthermore, a high standard of Moisture-Proof and Dust-Resistant Construction has been added to prevent intrusion of dust or water droplets. Highly durable, Fluorine Coating is applied to the top element surface and efficiently prevents condensation of moisture and repels smudge-causing substances.
Meticulous craftsmanship is demonstrated in every detail of the exterior design of the newly transformed SP 90mm macro lens. The user can feel it in the exquisitely smooth texture of the metallic barrel.
The lens features an optical construction of 14 elements in 11 groups, including one LD (Low Dispersion) and two XLD (eXtra Low Dispersion) glass elements that in consonance help to control lateral and on-axis chromatic aberrations at a very high level of performance. A Floating System works in tandem with the optical construction to efficiently compensate for inherent aberration changes subject to varying distances. Therefore, this lens ensures seamless and outstanding depictive capabilities across the entire shooting range – close or far.
Flare or ghosting can be detrimental to a decisive shot. A combination of 2 types of coating – eBAND (Extended Bandwidth & Angular-Dependency) layered on top of BBAR (Broad-Band Anti-Reflection) – dramatically improves anti-reflection efficiency to deliver flawless, crystal clear images even against harsh beams of sunlight.
Tamron has maintained a reputable standard for generations of 90mm macro lens models — all the way from manual focus lenses to the current AF models — for their exceptional depictive quality with spectacular bokeh. We also set a high standard to keep pace with the upward migration of digital cameras with advanced technical features and high pixel density.
We have now balanced these polar traits at a higher level: raising resolution performance to a new standard of sharp images, while rendering a soft and smooth transition in gradation of blur-effect in background objects. Optical simulations were thoroughly conducted to realize both well-tuned bokeh effects, while minimizing disturbance in dual-line smear of linear-shaped objects naturally blended into the overall bokeh effect.
The result: the SP 90mm F/2.8 MACRO VC sustains the tradition of excellence in optical design while extending the limit in cutting-edge optical performance and beautiful bokeh.
An accelerometer has been newly integrated into Tamron’s highly accredited VC to compensate for shakes on the x-y plane.
The accelerometer in unison with a gyro sensor detects and enables motion compensation for camera shakes for a maximum efficiency in image stabilization optimized for distance ranges from infinity to macro.
The USD (Ultrasonic Silent Drive) control software has been optimized for macro photography with increased focusing speed and positional accuracy when shooting in close-up settings. The AF drive responds rapidly yet quietly to zero in on the photographer’s point of interest and the Manual Focus Override enables instant shift in focus when necessary.
Moisture-Proof and Dust-Resistant Construction has been improved to an exceptionally high standard in lens protection, preventing any intrusion of dirt, dust, or raindrops. A rubber seal protects each switch on the lens and sealing member is applied to the mechanical interface between the focus ring and the lens housing. The new construction further expands opportunities for shooting, ensuring reliability even in harsh, windy conditions and immediately after rainfall.
Our attention to every engineering detail has yielded the most advanced optical and electro-mechanical design featured in the newest Tamron SP lenses, culminating in a new benchmark for high performance and visual elegance.
The design philosophy is based on human touch and is an integral factor in macro photography. The newly designed all-metallic barrel features an embedded concave ring at the base of the lens – for a firm hold and comfort necessary for a steady shot.
Switches are larger and reconfigured for smoother torque and the typeface has been redesigned for intuitive legibility.

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.
