The Tamron 28-300 F3.5-6.3 VC lens is a High-powered zoom lens designed for all SLR and digital SLR cameras. It covers everything from landscape and portrait to telephoto and macro. It is also equipped with Tamron's very efficient Vibration Compensation system. This award winning design is optimized with the combination of XR (Extra Refractive Index) and Low Dispersion (LD) Glass for a greater lens shapness. Its Aperture of F/22-F/40 (28mm-300mm) and ø67 Filter Diameter makes it to a point that undesired light would be filtered inevitably to obtain clear images. The lens minimizes illumination loss and suppresses abberations by its Internal Focusing System. It is compatible with APS-C and Full Frame Sensor DSLR Cameras.
Product Features in Detail
Tamron’s Unique State-of-the-Art In-Lens Image Stabilization System
Handheld camera shake is the leading cause of blurry and unsharp pictures. Several leading companies now make lenses with built-in optical image-stabilization systems that sense the amplitude and direction of the shake and compensate by moving optical groups within the lens. Tamron’s exclusive new Vibration Compensation (VC) system that’s built into the Tamron AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) Macro and the Tamron AF18-270mm F/3.5-6.3 Di-II VC LD Aspherical (IF) Macro lenses performs a similar function, but it executes it much more effectively due to its innovative breakthrough design.
While other image-stabilization systems can only correct the effects of camera shake in horizontal or vertical planes, Tamron’s VC system uses a tri-axial configuration that employs three pairs of driving coils and low-function ball bearings placed around the shake-compensating optical group to produce, in effect, a free-floating shake compensator. This simple, elegant system is able to compensate for camera shake that occurs in diagonal direction as well as for up-and-down and side-to-side movements. Furthermore, due to its simple, low-friction design it is more responsive and durable than previous systems. TheTamron 28-300mm VC and 18-270mm VC lenses incorporate a highly sensitive and accurate gyro sensor for detecting even the slightest hand shake, and that,combined with a 32-bit RISC CPU and Tamron’s proprietary Algorithms and actuator, provides unequalled real-world performance. The bottom line: Tamron VC provides up to a 4-stop advantage in shooting sharp handheld pictures at slower shutter speeds along with a smooth, stable viewfinder image that is the envy of other shake-control systems. You can expect to see the VC feature built into more Tamron lenses in the future.
Special Glass for Better Performance and More Compact Lens Designs
XR (Extra Refractive Index) glass can bend light rays at steeper angles, thereby decreasing the physical length of the lens while enhancing imaging performance by minimizing optical aberrations. This has allowed Tamron to develop a line of shorter, smaller-diameter, lighter lenses without sacrificing lens speed, and actually upgrading image quality compared to older designs. XR glass is costlier than conventional glass but it yields enhanced optical power distribution, making possible many of the outstanding and innovative lens designs that bear the XR designation. XR glass, with its superior light-bending power, makes it possible to design a short-barrel lens with the same light-gathering ability (aperture value) as a long-barrel lens—even with a smaller lens diameter. By using this principle Tamron has been able to shorten the length of the entire optical system and produce lighter, more compact lenses of the same speed, and also to provide greater zoom ranges in lenses that are much more convenient to carry and hand-hold.
Low Dispersion (LD) Glass for Greater Lens Sharpness
Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)
Hybrid Aspherical Elements Provide the Ultimate in Image Quality and Compactness
Tamron uses several hybrid aspherical lens elements in many lenses bearing the Aspherical designation. These innovative optics allow us to achieve the ultimate in image quality, and at the same time produce lenses that offer remarkable zoom ranges in extraordinarily compact packages. By perfecting theses cutting-edge advances for series production, Tamron has advanced the state of optical design, and virtually eliminated spherical aberration and image distortion from the high-power-zoom series.Through the effective application of Hybrid Aspherical Technology, one lens elemen tcan take the place of multiple elements without compromising performance. This is what allows us to produce remarkably compact long-range lenses that deliver a uniformly high level of image quality at all focal lengths and apertures.
Internal Focusing (IF) System
Internal focusing (IF) provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron’s Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions.
Zoom Lock (ZL) Feature
Another original Tamron mechanical engineering concept is the Zoom Lock (ZL), a simple convenience feature that prevents undesired extension of the lens barrel when carrying the camera/lens unit on a neck strap.
