Tamron Developing 90mm Macro

SP 90mm F/2.8 Di VC USD for Canon, Nikon and Sony mounts

September 13, 2012, 4PM JST, Saitama, Japan – Tamron Co., Ltd.
(President and CEO: Morio Ono / Headquarters: Saitama City), a leading
manufacturer of optical equipment, announced the development of a next
generation 90mm Macro lens for full-size SLR cameras. The lens features
completely redesigned optics, a proprietary VC (Vibration Compensation),
and USD (Ultrasonic Silent Drive). The SP 90mm F/2.8 Di VC USD will be
available in Canon, Nikon and Sony[3] mounts. The lens is expected to
ship by the end of 2012. Pricing information will be announced at a
later date.

Product Features
• Tamron has updated their
legendary 90mm Macro lens with a new, state-of-the-art optical design.
The lens, reborn for the age of digital photography, offers VC
(Vibration Compensation) and USD (Ultrasonic Silent Drive).
• Adopting a state-of-the-art optical design and a rounded diaphragm[4],
this lens carries on the long tradition of Tamron’s 90mm Macro lens in
delivering spectacular blur effects. Two XLD[5] (Extra Low Dispersion)
glasses and one LD (Low Dispersion) element reduce chromatic
aberrations, yielding sharp images and outstanding resolution.
• Tamron’s newly developed eBAND (Extended Bandwidth &
Angular-Dependency) Coating[6] delivers a dramatic improvement in
antireflection performance-significantly reducing flare and ghosting for
clearer, crisper images.
• The VC (Vibration Compensation) image stabilization mechanism reduces camera shake to deliver sharp images.[7]
• Features USD (Ultrasonic Silent Drive) to power a speedy AF drive together with a continuous manual focus mechanism.
• Incorporates IF (Internal Focus) system, which focuses by moving
only the internal lens group, rather than the front lens elements. The
overall length of the lens therefore does not change when focusing, thus
ensuring a broad working distance.
• Moisture-resistant construction helps prevent moisture from penetrating the lens.

Notice of Classification Code Change for Nikon Mounts
the introduction by Tamron of the first Nikon mount lens featuring an
internal AF motor, the 28-300mm Di VC (Model A20), all Nikon mount
lenses with the internal AF motor had used the classification code “N
II.” Lenses using a coupler system[11] without an internal AF motor were
designated as “N.” Because future Nikon lenses will have the internal
AF motor as a standard feature, Tamron has decided to simplify the
designation and consolidate all Nikon mount lenses as “N,” eliminating
the “N II” designation for future models. This classification code
change was made effective with the 18-270mm Di II VC PZD (Model B008).

“N” classification lenses with coupler systems (no internal AF motor)
are: SP 200-500mm Di (Model A08); and SP 180mm F/3.5 Di (Model B01).

[1] VC (Vibration Compensation) is Tamron’s proprietary image stabilization mechanism.
[2] USD (Ultrasonic Silent Drive) is Tamron’s proprietary ultrasonic motor drive.
[3] The
Sony mount does not include VC, as Sony digital SLR bodies include
image stabilization functionality. The Sony lens is designated as “SP
70-200mm F/2.8 Di USD”
[4] This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.
[5] The
XLD (Extra Low Dispersion) glass is made from specialized high-grade
glass, which offers greater chromatic aberration correction properties
than LD (Low Dispersion) elements.
[6] The eBAND (Extended Bandwidth
& Angular-Dependency) Coating is a new nanotechnology-based coating
technique developed by Tamron to reduce unwanted reflection.
[7] From 3m, the benefits of VC (Vibration Compensation) gradually decrease as the focus distance becomes closer.
[8] Length, entire length and weight values given are for the Nikon mount.
[9] Entire length is the distance between the tip of the lens and the tip of the protrusion.
[10] Length, entire length and weight values given are for the Nikon mount.
[11] Coupler system refers to a system that uses a shaft to harness the AF motor built into the camera body to operate the lens.

About Tamron
is a recognized leader in the manufacture of precision optics offering a
broad selection of meticulously engineered interchangeable lenses for
professional photographers and photo enthusiasts. Founded in 1950,
Tamron’s passion for innovation brought forth the ground-breaking
development of mass-produced hybrid Aspherical elements, giving way to
enormously popular compact, wide-range zoom lenses. Dynamic research and
development , committed to advanced optical engineering, has produced a
stream of award-winning Tamron lenses and defined the All-in-One zoom
lens category, exemplified by 2010’s 18-270mm Di II VC PZD.
Astonishingly compact and lightweight, this 15X zoom features
proprietary VC (Vibration Compensation) technology, effectively
counteracting image-degrading blur caused by camera shake along with a
fast, quiet PZD (Piezo Drive) autofocus mechanism. Tamron lenses deliver
a superb fusion of performance and value, enabling today’s
high-resolution digital SLR cameras to perform at their peak. Tamron’s
lenses have received numerous prestigious awards from around the world,
including 14 EISA (European Imaging & Sound Association) awards, 7
of which were awarded consecutively since 2006.
