Tamron’s New 90mm Offers Enhanced Functionality and Features
Tamron, a leading manufacturer of optics for diverse applications, has announced the launch of the SP 90mm F/2.8 Di VC USD 1:1 MACRO (Model F017). The new 90mm macro has been enhanced with advanced features and builds upon a legacy of superior optical performance.
Built upon the outstanding optical performance of the legendary Tamron 90mm Macro
Inheriting the optical design of the previous 90mm Macro lens (Model F004), the new Model F017 delivers the same excellent resolving power and remarkably soft background blur effects (bokeh). The 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 life-size close-ups to the most distant horizon, this new 90mm Macro lens achieves outstanding image quality.
Optimized for spectacular background blur effects (bokeh)
Earlier models of Tamron’s 90mm macro lens received high acclaim for their spectacular blur effects, and the new 90mm macro builds upon this legacy. The lens achieves both sharp, vivid images and spectacular background blur effects. This combination is highly prized by portrait photographers.
This lens provides 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
The control software program for the USD (Ultrasonic Silent Drive) actuator has been revised to provide substantially improved focusing speed and accuracy when using Auto Focus. The USD 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 protect areas of possible ingress surrounding switches, and the boundary between the focus ring and the lens barrel. These provide stronger protection against the intrusion of dirt, dust and moisture compared to the Moisture-Resistant Construction used previously.
A durable Fluorine Coating on the front element repels water and fingerprints
The water and oil repellant coating applied to the front element surface allows instant removal of dirt or smudges with ease.
Advanced coating technology reduces flare and ghosting
A combination of coatings 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)
When shooting a scene that includes a point-source of light in the subject background, marvelously tuned blur (bokeh) can be obtained without generating undesirable polygonal shapes of aperture patterns thanks to the circular aperture. The 9-blade diaphragm retains a nearly perfect circular opening even when stopped down by two stops.
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 that 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.
