ith flower-shaped lens hood. Compatible mounts: for Canon, Nikon (with built-in AF motor).
A high-performance, high-speed lens equipped with VC image stabilization.
The renowned VC image stabilization mechanism developed in-house by Tamron
is truly state-of-the-art. By building VC into fast, constant-aperture F/2.8 normal
zoom lens, the resulting synergy has resulted in a lens optimized to deliver
top-notch performance in practically any shooting situation. Lens components
have also benefitted from advances in production technology, resulting in greater
precision, reduced weight and enhanced strength. And since the VC compensator
lens moves parallel to the image plane via electronic control alone, the mechanism
is simplified and the lens itself is more compact.

glass. The optimum placement of three compound aspheric elements has
resulted in a more compact optical system overall while maintaining uniformly high
imaging performance. Two LD
(
Low Dispersion
)
lens elements are also employed
to effectively correct axial chromatic aberrations, which particularly important at
the longer focal lengths, and chromatic aberrations of magnification, which occur
primarily at the wide-angle end. Using these high-value glass materials with their
own special properties for multiple elements has enabled us to design a lens that
captures extraordinarily sharp images over the entire zoom range.
It’s what’s inside that captures light, and the moment.

)
Exposure: F/16 1/10 sec ISO200 WB: Auto Handheld photography
Tamron’s Di II lens series has been designed exclusively for use on
digital SLR cameras with APS
-
C size image sensors that are
somewhat smaller than the 35mm film format. By employing an
optical design optimized for the APS
-
C
-
format image circle, the lens
has been kept remarkably compact and lightweight for maximum
portability, while at the same time incorporating groundbreaking
specs in a flexible, user-friendly focal-length range.

over the zoom range,
with macro capability to 1:4.8.
With an optical system designed exclusively for optimum performance on digital
SLR cameras with APS
-
C size image sensors, the angular coverage range of this
lens is impressive. And even though it has a built-in VC image stabilization system, it
still delivers a close minimum focus distance of 0.29m
(
11.4 in
)
across the entire
zoom range. In short, it allows you to enjoy serious, high-quality macro photography
with unaccustomed convenience.
Uncompromising countermeasures to control ghosting and flare.
The new BBAR (Broad-Band Anti-Reflection) coatings adopted reduce internal lens
reflections and dispersion that cause ghosting and flare. The coatings enhance light
transmission in both the short and long wavelength ranges, ensuring excellent
performance in virtually any shooting condition. Additionally, specially formulated
internal surface coatings have been applied to the cemented surfaces of all lens
elements to ensure sharp, high-contrast images and flawless color reproduction.

For this reason, when a lens exclusively for APS

sensors on digital cameras is used on a 35mm format
camera, vignetting may occur, as demonstrated in the
photograph above (photograph is an image).
The image circle of an APS

C size
sensor is not able to cover the
entire area of 35mm film.
When attached to a 35mm format camera, peripheral areas of the image will
be dark (vignetting will occur). Please note that this lens is not designed for
use on 35mm film cameras or digital SLR cameras with image sensors larger
than the APS
-
C size.
