The 200-500mm f/5-6.3 Tamron Di is an ultra telephoto
zoom allowing you to acquire far off subjects and bring them in close while at the same compressing the space between your primary subject and your background scene for professional results. Even though it encompasses a range going up to 500mm, the layout is relatively compact and lightweight. When mounted upon an
APS-C image size DSLR camera, it delivers a 35mm
focal length of 760mm for ultra super telephoto images.
I have discovered that the majority of
telephoto lenses end up getting negative reviews, not that these lenses are inferior, but because people do not know how to properly photograph with them.
The lens optical design allows you to zoom in as close as 8.2' from your primary subject at just about any focal length, while delivering a maximum magnification 1:5 ratio at it's maximum 500mm end, providing impressive, dynamic photos of small subjects.
This lens also features a detachable Filter Control ring Effect, allowing you to rotate your filter in a desired position while the hood is attached, allowing you to make minute fine-tuning with a polarizing filter. The Polarizing effect can be confirmed by looking through your viewfinder, all while with the hood in place to prevent extraneous light from getting into the lens. The Digitally Integrated Design (Di) is a label Tamron gives all it's lenses with optical systems engineered to enhance performance characteristics of DSLR cameras. This particular lens does not feature a built-in lens motor.

Minimum Object Distance of 2.5m (8.2 ft.) throughout the Range
Tamron's new 200-500mm enables you to get as close as 2.5m (8.2ft.) from your main subject at any focal length and provides a useful maximum magnification ratio of 1:5.0 at the 500mm end, allowing you to take dynamic and impressive pictures of small subjects.
The Detachable Filter Effect Control
The Filter Effect Control is designed to rotate the
filter to the desired position with the hood attached, enabling you to simultaneously perform minute adjustments to PL filter compensation. You can confirm the Polarizing effect through the viewfinder, all while using the hood to prevent harmful light from entering the lens.
This powerful ultra telephoto zoom lens weighs a mere 1237 grams (43.6 oz.) through the use of engineering plastic materials for parts that compose the main barrel that provide strength sufficient for industrial applications, yet offer dimensional stability. The tripod mount, detachable in one touch, is made of magnesium alloy that reconcile light-weight and high rigidity, resulting in enhanced balance and ease of use in hand-held shooting.
New Addition to the Di-series
The lens features Tamron's "Di" (Digitally Integrated Design) optical system to meet the performance characteristics of
digital SLR cameras as well as
SLR film cameras. When mounted on an APS-C size digital SLR camera, it provides a
focal length coverage equivalent to a 310-760mm, covering the ultra telephoto zoom range.
Features Two LD Elements That Provide Sharp and Clear Images Chromatic aberration is likely to be reproduced in an image as color blur or color shift. On-axis chromatic aberration in particular, that can be a problem in ultra telephoto lenses, causes color blur in the center of an image. This zoom lens features two LD (Low Dispersion) elements made of special glass materials that have low dispersion indices to confine dispersion of spectra, a cause of chromatic aberrations, to the absolute minimum, and provides sharp and clear images.
SP-Series Lens Featuring High Design Specifications
Tamron's SP (Super Performance) series is a line of high performance lenses featuring high design specifications. In designing the SP series lenses, the first and foremost priority is put on superior specifications and outstanding performance free from cost restraint. Therefore, SP lenses featuring impressive and innovative designs are concept models among Tamron lenses.
Optical System Designed to Provide Outstanding Image Quality with High Contrast
The lens features an optical system balanced at a remarkably high level to provide high resolution while achieving high contrast even in the low frequency range. Therefore, Tamron's 200-500mm provides outstanding images that are uniform and sharp over the entire image field.
Internal focusing lens (also known as IF) is a
photographic lens design in which focus is shifted by moving the inner lens group or groups only, without any rotation or shifting of the front lens element. This makes it easy to use, for example, a screwed-in
polarizing filter or a petal shaped lens hood. During
macro photography, using an internal focus lens reduces the risk of the front of the lens accidentally hitting the subject during focusing as the front element does not move.
