Product Description
-------------------
Example Photograph
The legendary 90mm F2.8 has been available in different improved
versions for over 30 years, and therefore stands in a long macro
tradition in the super performance series. This light super
performance (SP)* macro-lens offers a 1:1 magnification ratio and
pin-sharp images with beautifully blurred backgrounds that make
your subject stand out. The Di version was adapted to the demands
of digital SLR cameras and characterized by a new multi-coating
with which the stray-light behaviour of the lens was optimized.
The Tamron 90mm is often called the "portrait macro", because the
focal length is also ideally suited for portraits. The new
version can be also be used on full frame or 35mm cameras.
*SP (Super Performance) - This lens belongs to the Super
performance (SP) class of Tamron lenses distinguished by ultra
high optical and mechanical quality.
Equally at home on APS-C DSLRs, rendering a picture angle
equivalent of the 140mm lens on a full-frame DSLR or 35mm SLR
camera, photographers appreciate the resulting increase in front
element-to-subject distance and close-up photography. In
addition, this 135mm-like picture angle is well-suited for
environmental portraiture. Extraordinary sharpness, striking
contrast and a remarkable absence of distortion combine to
produce images of exceptional calibre.
9 Diaphragm Blades
------------------
The number of diaphragm blades affects the "shape" of the blur in
out-of-focus areas of the image. This is more important in
portraiture, where the aperture setting is often wide open, and
macro photography, where the high magnification results in
blurred background and foreground even at narrow apertures. When
backgrounds are soft and blurred, not only is the effect very
pleasing and "photographic", but it also serves to isolate the
subject from a distracting background, providing a
professional-looking image. A high number of blades provide a
rounder shape to the aperture, which in turn makes the shape of
the blur more circular and much more natural.
Super Performance
Super Performance (SP)
----------------------
Tamron SP (Super Performance) series is a line of
ultra-high-performance lenses designed and manufactured to the
exacting specifications demanded by professionals and others who
require the highest possible image quality. In creating SP lenses
Tamron’s optical designers put their foremost priority on
achieving superior performance parameters—they are all designed
to a higher standard with little regard for cost constraints. As
a result, Tamron lenses bearing the SP designation feature
impressive and innovative designs that have established an
enviable reputation for excellence among those knowledgeable
photographers that demand the very best.
Di Anti-Reflection
------------------
One major difference between digital and film cameras is how
internal reflections may occur and to what extent. These internal
reflections can cause unwanted flare or ghosting on the final
image. In a film camera, internal reflections can be created
inside the mirror box of the camera or from light reflecting off
the film surface itself. However in a digital camera, the almost
mirror-like surfaces of CCD and CMOS sensors make this much more
of a challenge. Di lenses offer new anti-reflection
countermeasures that are essential in lenses designed for use
with digital cameras. The SP AF90mm Di features an improved
coating technology that reduces the problematic reflections to
the absolute minimum.
Focal Length
------------
As a medium telephoto focal length, 90mm is particularly useful
as a portrait macro lens when used with a film camera. When used
on a digital SLR camera with a smaller image sensor, the lens
provides a focal length equivalent to that of 140mm, so it can be
used conveniently as a telephoto macro lens.
AF/MF Switch Mechanism
Auto-focus/Manual-focus (AF/MF) Switch Mechanism
------------------------------------------------
The ability to switch quickly between auto-focus (AF) and
manual-focus (MF) is a great asset in many types of shooting,
especially sports and nature photography. This is easily
accomplished with Tamron’s ingenious AF/MF system. By simply
sliding the focus ring back and forth between the two positions
you can select either the AF or MF focusing position. In
manual-focus mode Tamron lenses provide smooth, precise manual
focusing by turning their wide, well-textured focusing rings.
