The SP 90mm F/2.8 Di MACRO 1:1 VC USD (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 stabilisation 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. Feel it in the exquisitely smooth texture of the metallic barrel.
Outstanding depictive capabilities and anti-reflection efficiency
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.
Commitment to extending a legacy of bokeh with elegance
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 realise both well-tuned bokeh effects, while minimising 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.
Optimally tuned USD actuator for macro photography with manual override for instantaneous focus control
The USD (Ultrasonic Silent Drive) control software has been optimised 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.
High-performance features behind every design aesthetic
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.
* The Sony mount does not include VC, as Sony digital SLR bodies include image stabilisation functionality. The Sony lens is designated as “SP 90mm F/2.8 Di Macro 1:1 USD”.
*** The diaphragm retains a nearly circular shape at aperture settings down to f/5.6.
