The full power of macro

Superior image quality in 1:1 lifesize photography – now with ultrasonic autofocus and image stabilisation

Photo Review Editor's Choice - click to see the full review on their websiteTamron Model F004 - EISA Best Lens 2013-2014Images of astounding sharpness, augmented by natural blur effects. Tamron’s classic 90mm macro lens is reborn to shoot images even more exquisite. Compatible with full-size DSLRs sensors, this high-resolution macro lens captures even the tiniest details with stunning clarity.

As well, the addtion of Tamron's VC (Vibration Compensation)* makes this new lens ideal for general telephoto use such as handheld natural-light portraiture, where the wide maximum aperture is complemented by the image stabilisation.

USD (Ultrasonic Drive) autofocus provides a speedy, accurate response to faster-moving subjects.

Powerful resolution with beautiful blur effects

Two XLD (Extra Low Dispersion) glass elements** made from specialised, high-grade glass and one LD (Low Dispersion) element combine to thoroughly correct aberration. As well, the rounded diaphragm shape at wide apertures*** delivers spectacular blur of out-of-focus objects. Pinpoint focus on the subject and soft, natural-looking blur in foregrounds and backgrounds combine for images with a richer, more satisfying ambience.

* 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 XLD glass has an extremely lowlight dispersion ratio similar to fluorite.
*** The diaphragm retains a nearly circular shape at aperture settings down to f/5.6.

LD
Low Dispersion

Sharpens edges by reducing 'colour fringing'

Chromatic aberration occurs when a lens element refracts different wavelengths of a ray of light – its rainbow colours – at very slightly different angles. This results in the 'colour fringing' that reduces the sharpness of an image. LD elements are made from special glass materials with extremely low dispersion indices (i.e. the refraction of a ray of light into rainbow colours is extremely narrow). Thus they effectively compensate for chromatic aberration at the centre of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (toward the edges of the field) that often occurs at short (wideangle) focal lengths.

Although costly, LD glass materials result in clear, vivid image quality.

Low Disperison glass

XLD
Extra Low Dispersion

Dispersive properties even lower than LD elements

Extra Low Dispersion lens elements are made from a special high-grade glass that has dispersive properties (i.e. where refraction causes the dispersion of white light into spectral hues) even lower than standard LD lenses, in fact being similar to those of fluorite. In combination with LD elements, these make for an optimal optical design that delivers superb resolution with advanced correction of axial chromatic and magnification aberrations – major inhibitors of image quality.

The result is a lens that delivers sharp contrast and better descriptive performance throughout the entire zoom range.

eBANDeBAND Coating

Advanced lens coating produces even sharper, crisper images

This new coating technique developed by Tamron deploys a nano-structured* layer with dimensions smaller than the wavelengths of visible rays of light. Called eBAND (extended Bandwidth & ANgular-Dependency), its ultra-low refractive index, combined with the sophisticated multiple-layer coatings underneath, yields significant anti-reflection properties, absolutely minimising flare and ghosting to deliver sharp, crisp images.

Attention-grabbing blur effects at wider apertures

Use depth of field more creatively with spectacular but natural-looking background blur.

The rounded outline diaphragm of the lens is retained even when stopped down to f/5.6. Blur highlights in a photo reflect the shape of the aperture, and they are a much more prominent feature at wider apertures. Especially in higher-speed lens, this important optical design element results in more attractive, natural-looking images.


Other features

1:1 Maximum magnification ratio

The powerful maximum magnification ratio of 1:1 reproduces a life-size image of the subject on the image sensor. The Tamron 90mm Macro captures a minute world with a level of crisp detail that cannot be easily seen by the naked eye.

VCVibration Compensation

Stabilises camera blur for sharp images in low light

If you're shooting handheld when light is low, especially with longer lenses, your camera's shutter speeds can extend to a point where the image may turn out blurred due to camera shake. Tamron's VC tracks this shake and neutralises it for sharper images without the inconvenience of a tripod or the artificiality of a flash, in much lower light.

Tamron's unique VC mechanism uses a proprietary actuator and algorithms to deliver an extremely stable viewfinder image with excellent tracking. The tri-axial system uses three driving coils to move internal optical components within the VC lens electromagnetically, based on signals originating from three ball bearings, made from either steel or ceramic. The VC lens elements are held in place only by contact with the balls, achieving smooth movement with minimal friction.

Tamron's original moving magnet system employed a heavy magnet positioned near the moving VC lens element. The improved VC reverses the positions of magnet and coil and attaches the VC optic to the coil. This moving coil is lighter than the magnet, and as this reduces the load on the drive system, both the VC unit and the lens are lighter and more compact.

USD Ultrasonic Silent DriveUltrasonic Silent Drive

'Travelling waves' generate a fast, smooth AF movement

This extremely quiet motor is ideal for photography of events, weddings, theatre or musical performances, as well as crucial moments on the golf course – any situation where autofocus noise is obtrusive. Major improvements in autofocus response and tracking ability over standard DC motors make for instantaneous focusing and spontaneous shooting of rapidly moving subjects.

Watch this feature in action on our YouTube channelTamron’s USD works with the high-frequency ultrasonic vibrations that are produced by a ring called a ‘stator’. Energy from the vibrations is used to rotate an attached metallic ring known as the ‘rotor’. Piezoelectric ceramic is a material that produces ultrasonic vibrations when voltage of a specific frequency is applied is arranged in a ring formation on the stator. This electrode configuration of piezoelectric ceramic causes two ultrasonic vibrations to occur in the stator. By effectively combining these two ultrasonic vibrations, it is possible to convert the energy from the vibrations that produce simple motion into energy known as ‘deflective travelling waves’, which move around the circumference of the ring. The friction between these deflective travelling waves created on the metallic surface of the stator and the surface of the rotor produces force, causing the rotor to rotate. Attached to the rotor is the focusing lens, which is given a fast, smooth autofocus movement.

IF
Internal Focusing

Focusing elements inside the optical design make for better handling

In many lenses, the front elements move back and forth to alter the focus distance. With an internal focusing (IF) mechanism, the focusing elements are inside the optical design. Because the front lens elements remain static, the lens’ actual length does not change. This provides several benefits both to the image and during photography:

  • The barrel is not subject to stray light entering from external helicoids that can adversely affect image quality
  • A non-rotating front filter thread makes it easier to use filters such as graduated filters and polarisers
  • A flower-shaped lens hood will remain in the correct position to most effectively shield the lens from stray light
  • Better balance and more predictable handling because the lens length does not change during focusing
  • Generally, a much closer minimum focusing distance throughout the zoom range
  • Improved optical performance by minimising loss of illumination at the corners of the image field (vignetting)
  • Suppression of other aberrations that become more troublesome at different focusing positions.

Integrated focus cam optimises internal focusing

Tamron's Integrated Focus Cam is a precision mechanical component that optimises the co-ordinated movement of the Internal Focusing (IF) system with the Multiple Cam Zoom Mechanism. This ingenious mechanism ensures accurate and seamless positioning of all the internal elements within the lens and coordinates them with the external zoom and focus controls.

Moisture resistance adds protection

Moisture-resistant body construction helps prevent water from penetrating the lens, making it well suited ideal for travel and shooting outdoors.

DMF
Fine manual focus adjustments can be made quickly and easily

The USD motor is complemented by DMF (Direct Manual Focus) to enable manual fine-tuning after autofocusing if and when necessary. No need to engage a switch – just gently rotate the focus ring on the lens.
