The Tamron SP 90mm F/2.8 Di VC USD 1:1 Macro Lens builds on a legacy of superior optical performance with modern innovations. The lens features quick AF speed with a USD motor is a great benefit when you put this lens to double duty as a portrait lens. Since nice photos also happen in bad weather the lens is moisture and dust resistant and features a durable folurine coating on the front element to shed water and grime. The working distance on the 90mm lens is great for flowers and slower insects, and the fast f/2.8 aperture will really help isolate your subject from the backgrouond.
Built upon the outstanding optical performance of the legendary Tamron 90mm MacroInheriting 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 advanced construction includes one LD (Low Dispersion) specialized glass element that maximally limits the dispersion properties of light and two XLD (eXtra Low Dispersion) glass elements that correct dispersion properties to an even greater extent. The special elements optimally compensate for on-axis and lateral chromatic aberrations from macro shooting range to infinity. Furthermore, 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 1:1, 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. To continue this commitment, thorough optical simulations were conducted. Careful examinations were performed to minimize any blurring with a doubled image appearing for a single line because that phenomenon has a considerably negative impact on background image quality. As a result, the lens achieves both sharp, vivid images and spectacular background blur effects. This combination is highly prized by portrait photographers.
Moisture-Proof and Dust-Resistant ConstructionSpecial 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. This additional protection assures even more wide-ranging opportunities for using this lens.
A durable Fluorine Coating on the front element repels water and fingerprintsThe water and oil repellant coating applied to the front element surface allows instant removal of dirt or smudges with ease. Even careful photographers can’t stop a jumping spider from jumping onto the front of their lens, and Tamron knows it.
Advanced coating technology reduces flare and ghostingTwo 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)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 lensThe 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 which is great for insects. 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.
Compatibility with TAMRON TAP-in ConsoleAlways as new as tomorrow: You can update firmware, customize autofocus positions and adjust the mechanical setup and preferences of the 90mm lens by simply attaching it to the TAMRON TAP-in Console™ and connecting it via USB to a personal computer.
