Tamron SP 90mm f/2.8 Di VC USD Macro макро линза для Canon аренда

Built upon the outstanding optical performance of the legendary Tamron 90mm Macro
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 which 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 shakes 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
The control software program for the USD (Ultrasonic Silent Drive) actuator has been revised to provide substantially improved focusing speed and accuracy when using AF. 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
Areas of possible ingress surrounding switches and the boundary between the focus ring and the lens barrel are protected by special seals. 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 fingerprints
The water and oil repellant coating applied to the front element surface allows instant removal of dirt or smudges with ease. The coating also provides a reasonable level of durability, and will sustain its effectiveness for years.

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)
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 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.

Compatibility with TAMRON TAP-in Console
Always 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. (The TAP-in Console is an optional accessory that will be released in March.)

Specifications

* Length is the distance from the front tip of the lens to the lens mount face.
** The Sony mount version does not include VC since Sony digital SLR bodies incorporate built-in image stabilization functionality.
