Product Description
The worlds first F2.8 all-in-one zoom lens for full-frame mirrorless
cameras
A remarkable first for an all-in-one zoom lens: the 28-200mm F2.8-5.6
achieves a fast F2.8 aperture at the 28mm wide-angle end. Additionally, maximum
apertures at intermediate zoom ranges are F3.5 at 50mm, F4.5 at 100mm, and F5.6
at 150mm through 200mm. As an unprecedented all-in-one zoom that combines fast
aperture with compact size, the 28-200mm F2.8-5.6 delivers greater versatility
and usefulness than ever before available.
Lightweight and compact size for superior mobility
Tamrons series of full-frame mirrorless camera lenses, starting with the
28-75mm F2.8 (Model A036), has been developed with the overall goal of balancing
high performance with convenience. In addition to the series-standard 67mm
filter diameter, and leveraging the camera integrated image stabilization,
engineers concentrated on achieving compact size and light weight. Length is
just 4.6, maximum diameter is 74mm, and the weight is a mere 20.3 oz. With a
size that offers excellent portability, the lens lightens your load, allowing
you to travel comfortably and shoot unencumbered.
Uncompromising image quality that lets you focus on creativity
This new zoom lens contains 18 elements in 14 groups. A generous assortment
of special lens elements that includes GM (Glass Molded Aspherical), hybrid
aspherical, XLD (eXtra Low Dispersion) and LD (Low Dispersion) lens elements is
precisely arranged to effectively control chromatic and other aberrations,
enabling high resolving power. Meanwhile, the BBAR (Broad-Band Anti-Reflection)
Coating provides powerful anti-reflection properties to effectively reduce
ghosting and flare, resulting in clear and crisp images. In-camera correction
features are utilized to mitigate distortion and shading to achieve uniformly
high image quality from edge-to-edge at all zoom settings. Tamron has
concentrated all its all-in-one zoom technologies into achieving optical
performance that sets a new standard among existing all-in-one zoom lenses. From
casual snaps to serious photos, this single lens lets you enjoy a wide range of
shooting situations with complete freedom of composition.
Superior up-close shooting performance
The 28-200mm F2.8-5.6 delivers superior close-up shooting performance for an
all-in-one zoom. At the 28mm wide-angle end the MOD (Minimum Object Distance) is
7.5, achieving a maximum magnification ratio of 1:3.1. This performance,
combined with the fast F2.8 aperture, allows users to move in close so that the
subject is large while simultaneously showcasing a beautifully blurred
background. Close-up shooting is remarkable at the telephoto end as well, with
an MOD of 31.5 and maximum magnification ratio of 1:3.8. Users can capture
impressive images with highly blurred backgrounds and create exceptional
compositions.
The RXD stepping motor unit is exceptionally quiet
The AF drive incorporates a sensor that accurately detects the position of
the lens while the RXD motor unit delivers optimized AF control. This achieves
very fast and accurate autofocus operation, allowing users to maintain
tack-sharp focus on continuously moving subjects or when filming video. The
exceedingly quiet operation is an important advantage because it virtually
eliminates extraneous sounds during video recording. In addition, the compact
configuration of the RXD AF drive system contributes to the unprecedented size
and weight reduction.
A full family of superb, compact lenses made especially for mirrorless
cameras
The 28-200mm F2.8-5.6 zoom is based on Tamrons stratagem of creating a
series of lenses for full-frame mirrorless cameras that leverage the
characteristics of compact camera bodies. Consequently, photographers can more
easily enjoy various combinations of interchangeable lenses. For example, when
the Model A071 is combined with the 17-28mm F2.8 (Model A046), the combined
weight of the two lenses is less than 35.1 oz. This lightweight, portable zoom
set covers everything from wide-angle to telephoto with a zoom range of
17-200mm. Additionally, when combined with a lens from Tamrons series of fixed
focal lenses such as the 20mm F2.8 (Model F050) or 24mm F2.8 (Model F051), the
weight is less than 28.2 oz., expanding the possibilities of shooting at the
wide-angle end without adding excessive weight or bulk.
All lenses in the series share the common filter diameter of 67mm, thereby
eliminating the hassle associated with using different size filters and lens
caps. Costly filters (e.g., PL, ND, etc.) can be shared instead of buying
separate units for each lens. In this way, Tamron has expanded its series of
lenses to make it truly practical to carry multiple lenses at the same time.
Moisture-Resistant Construction, Fluorine Coating, and Zoom Lock switch
Seals are located at the lens mount area and other critical locations to
deter infiltration of moisture and/or rain drops and afford Moisture-Resistant
Construction. This feature provides an additional layer of protection when
shooting outdoors under adverse weather conditions. Also, the front surface of
the lens element is coated with a protective fluorine compound that has
excellent water- and oil-repellant qualities. The lens surface is easier to wipe
clean and is less vulnerable to the damaging effects of dirt, moisture or oily
fingerprints, allowing for much easier maintenance. Additionally, the handy Zoom
Lock switch prevents unwanted barrel extension during transportation.
Compatible with main camera-specific features and functions:
Tamrons new 28-200mm F2.8-5.6 is compatible with many of the advanced features
that are specific to certain mirrorless cameras. These include the following:
- Fast Hybrid AF
- Eye AF
- Direct Manual Focus (DMF)
- In-camera lens correction (shading, chromatic aberration, distortion)
- Camera-based lens unit firmware updates
