1. Inheriting the broadest focal length range in its class of ultra-wideangle
zoom lenses
The new Model B023 achieves a broad
focal length range of 10-24mm, the largest range among ultra-wideangle zoom
lenses for APS-C DSLR cameras. This is the 35mm equivalent of covering a very wideangle
of view, from 16mm ultra-wideangle to 37mm semi-wideangle. A photographer can
enjoy diverse wideangle expressions with just this one lens, from dynamic
landscapes far beyond the normal human field of vision to simple, casual
snapshots.
2. Improved optical performance across the entire zoom range
The optical design of the new Model B023
consists of 16 lens elements in 11 groups. Special lens elements are utilized
in an optimum configuration of one LD (Low Dispersion) lens element, one XLD
glass element, one molded glass aspherical element, and one hybrid aspherical
lens. While curbing an increase in the size of the optical system, the new lens
very effectively compensates for a wide variety of aberrations in the entire
zoom range, including transverse chromatic aberration, comatic aberration and
distortions that tend to become more prominent with a wideangle lens. Tamron’s highly regarded BBAR
(Broad-Band Anti-Reflection) Coating and the optical design paying close
attention to internal reflections in the lens barrel also curb the effects of
harmful light rays that tend to occur with a wideangle lens, achieving
excellent resistance against ghosting and flare seen in backlighting situations.
3. 4-Stop Vibration Compensation that is especially useful in low light
conditions
In response to the requests of many
customers who have asked the company to equip a wideangle lens with image
stabilization, we have now installed Tamron’s acclaimed VC (Vibration
Compensation) on the new Model B023. Optimizing the actuator and the control
algorithm has made it possible to incorporate the VC, while maintaining the
compact design of the previous Model B001. The VC especially enhances the
photographer’s freedom in handheld shooting at dusk or in a dimly lit room, and
under other relatively low light conditions, as the mechanism proves
particularly effective in the shooting conditions with slower shutter speeds.
4. Equipped for the first time with the new HLD with outstanding driving
power and stability
Tamron’s new HLD (High/Low torque modulated Drive) has been developed for use as the AF
drive system for Model B023. With its outstanding driving power and stability,
the HLD is capable of smoothly controlling the AF mechanism of the new Model B023
that is actually equipped with large focusing lens elements. When shooting in
AF mode, the Full-time Manual Focus override allows you to instantly make fine
focusing adjustments manually, without having to switch between modes.
5. Compressed into a compact body with structural ingenuity
While enhancing image quality, adding
new functions and substantially improving the basic performance, Model B023’s
space-saving design has ensured an optimum configuration for components such as
the VC and AF unit, thus successfully reducing overall length compared to the
previous Model B001. The lightweight and compact body with outstanding ease of
use will prove to be very well-balanced when attached to an APS-C DSLR camera.
6. An even more user-friendly lens with Fluorine Coating and
Moisture-Resistant Construction
The front surface of the foremost lens
element is coated with a protective fluorine compound that is water- and
oil-repellant. The lens surface is easier to wipe clean and is less vulnerable
to the damaging effects of dirt, dust, moisture and fingerprints, allowing for
much easier maintenance. For
greater protection when shooting outdoors, leak-proof seals throughout the lens
barrel help protect your equipment.
7. Electromagnetic
diaphragm system now used also for Nikon-mount lenses
An
electromagnetic diaphragm system, which has been a standard feature for
Canon-mount lenses, is now employed in Nikon-mount lenses. More
precise diaphragm and aperture control is possible because the diaphragm blades
are driven and controlled by a motor through electronic pulse signals.
8. Compatible with TAMRON TAP-in ConsoleTM, an optional accessory product
The optional
TAP-in Console provides a USB connection to your personal computer, enabling
you to easily update your lens’s firmware as well as customize features
including fine adjustments to the AF and VC.
9. External design placing importance on functionality and ease of use
While inheriting the design that makes
use of a lot of organic curves and the delicately polished form down to fine
details that characterize the SP lens series, the new Model B023 comes with a
highly sophisticated design that also places much importance on the lens’s
functionality and ease of use, featuring an overall form that faithfully
encompasses the internal structures within, a slim Luminous Gold brand ring,
the switch shape and the distance-scale window design.
