This updated 90mm VC USD lens inherits many of the outstanding features of its predecessor, however is now improved with an enhanced VC image stabilization with XY-Shift compensation making handheld shots even easier from infinity to Macro. The near silent USD focusing system has also been improved and fine-tuned to give outstanding speed and control, regardless of whether you are focusing at infinity, or at macro distances where the USD focusing continues to compensate for slight movements common with handholding at short distances.
The construction of the lens now includes a newly designed all-metallic barrel as part of Tamron’s “New SP” design, with larger switches which are reconfigured for smoother function. Tamron have incorporated a new standard of Moisture-Proof & Dust-Resistant construction that assures even more wide-ranging opportunities for using this lens, plus Tamron’s Fluorine coating which is applied to the front element to help repel water & oil, makes the front element easy to keep clean & condensation free.
Built upon the outstanding optical performance of the legendary Tamron 90mm Macro
The new 90mm VC USD lens (Model F017) delivers excellent resolving power and remarkably soft background blur effects (bokeh). The advanced construction includes one LD (Low Dispersion) glass element and two XLD (eXtra Low Dispersion) glass elements. These special elements optimally compensate for on-axis and lateral chromatic aberrations from macro through to infinity. Furthermore, the optical design ensures the best imaging performance at any range by adopting the Floating System that shifts the location of a group of elements to the best possible position as the focusing group travels relative to shooting distances. From 1:1, life-size close-ups to the most distant horizon, this new 90mm Macro lens achieves outstanding image quality.
VC enhanced with shift compensation
An accelerometer has been integrated into Tamron’s highly accredited VC (Vibration Compensation) to compensate for movement on the x-y plane. In unison with a gyro sensor, the accelerometer detects and enables motion compensation for camera shake, providing maximum efficiency in image stabilization optimized for all distance ranges from infinity to macro.
USD actuator maximized for macro photography is fast, accurate and quiet
With improved focusing speed and accuracy, the latest USD (Ultrasonic Silent Drive) focusing system quickly addresses any out-of-focus condition caused by back-and-forth camera movement (which commonly occurs during macro photography) ensuring better results when shooting at close range.
Moisture-Proof and Dust-Resistant Construction
Special seals provide stronger protection against the intrusion of dirt, dust and moisture around switches and the boundary between the focus ring and the lens barrel. This latest advance over the Moisture-Resistant Construction used previously, provides additional protection & assures even more wide-ranging opportunities for using this lens.
A durable Fluorine Coating on the front element repels water and fingerprints
The Fluorine Coating is a water and oil repellant coating applied to the front element surface making it much easier to keep clean & remove dust & deposits with ease.
Advanced coating technology reduces flare and ghosting
Two advanced coating technologies, both providing outstanding anti-reflection performance, are applied to critical element surfaces for maximum light transmission. eBAND (Extended Bandwidth & Angular-Dependency) Coating boasts outstanding anti-reflection performance across nearly the entire range of visible rays, and BBAR (Broad-Band Anti-Reflection) Coating utilizes traditional multi-layered, anti-reflection technology. This combination virtually eliminates extraneous reflections and substantially reduces ghosting and flare which enables the lens to achieve flawless, crystal clear images.
Use of circular aperture to achieve beautiful, rounded blur effects (bokeh)
The 9-blade diaphragm retains a nearly perfect circular opening when stopped down by just two stops, creating beautiful circular highlight blur (bokeh) for pinpoints of light in the out of focus background. In combination with the optical design, spectacular background blur effects can be achieved.
Focusing options perfectly suited to a macro lens
The new 90mm macro has a focus limiter that makes it possible to shorten the time for accurately focusing on a subject when the working range is known. The lens also features an Internal Focusing system, so the overall length of the lens never changes, not even when focusing. As a result, the user is assured of a comfortable working distance of at least 139 mm (5.5 in.) from the front of the lens. In addition, the lens is equipped with a Full-time Manual Focus override mechanism which makes it possible to flexibly choose focal points. Even with the AF driving system in action, it is possible to instantaneously override it to make manual fine focusing adjustments without switching the AF-MF mode back and forth.
