A High Powered Zoom Exclusively For DSLR Cameras

Tamron AF 18-200mm F/3.5-6.3 XR Di II LD Lens Tamron AF18-200mm XR Di-II LD Aspherical (IF) MACRO A high powered zoom lens created exclusively for use on DSLR cameras featuring an APS-C image sensor Several years subsequent to its announcement, the present AF 28-300mm zoom is even now a highly valued favorite by photographers from around the globe as a symbolic model of high powered zooms.

If you need a low light lens, this isn't it. If your primary objective is to take pictures in low light situation such as weddings and concerts, in the 18-200mm range you need 2 lenses, get the 18-50mm f/2.8 Sigma or Tamron 17-50 VC and a 70-200mm f/2.8 lens instead.

With the market flood of DSLR cameras in recent times, using high powered zoom lenses has increasingly become popular as these high powered zoom lenses impart the handling conveniences for a number of photographic situations and the ability to shoot ultra telephoto images without ever changing a lens. The widespread popularity of this particular focal length induced Tamron to develop two new zooms to further fulfill the needs of DSLR photographers.

The upshot is a successful creation of a fresh zoom lens made to be used on DSLR cameras only. The wide-angle through ultra tele focal length of this particular lens will give DSLR camera owners the pleasure of digital photography with convenience and reassurance

Digitally Integrated Design (Di), is a title Tamron includes on their lenses with optical systems engineered to compliment performance characteristics of DSLR cameras. DI Lenses include the following advantages: Reduced peripheral light fall-off, Improved Resolution, chromatic aberration reduction, ghosting and flare compensation

By using an optical layout for only use on an APS-C DSLR camera, this high powered zoom lens delivers focal length similar to the Tamron 28-300mm ( a 35mm equivalent format). Therefore, one can meet almost every photographic challenge using this single zoom without a need to change lenses. When teamed up with the Tamron AF 11-18mm zoom, announced by Tamron during the same time, you can now thoroughly enjoy DSLR photography with a combination focal length range of 17-300mm.

The Optical System employs Special Glass which is Optimized for DSLR compatibility as a way to further Enhance Optical Quality using a compact layout. This new 18-200mm high powered zoom employs a fresh new optical layout using Extra Refractive Index (XR) glass using an innovative effort to optimize the complete optical power distribution all the way through total zoom range. This layout diminishes many aberrations to an absolute minimum and realizes remarkable downsizing while doing it. In addition, two Low Dispersion LD) glass elements and three aspherical hybrid lens elements are employed to achieve effective compensation of lateral and on-axis and chromatic aberration, a crucial factor in enhancing optical quality.

Using the zoom past 135mm you'll require a tripod unless you have excellent light to steer clear of blurring from camera movement.


The term hyperzoom or superzoom is used to promote photographic zoom lenses with unconventionally large focal length factors, typically more than 4 and ranging up to 15, e.g., 35 mm to 350 mm. The largest ratio for digital SLR cameras is held by the Tamron 18270 mm, giving 15. Some Digital Camera Review by Gene Wrights have even larger zoom ratios up to 35. For movie and television use, Panavision holds the record with their 300X HD Lens.

While superzoom lenses have improved greatly in recent years, they still have a number of drawbacks in comparison with shorter-range zooms and prime lenses. Most notable is the much increased likelihood of significant distortions of the image at both extreme ends of the range. Other potential problems include smaller maximum aperture and poorer autofocus performance

The minimal factor used here is 5 or more. A 28200 mm has a 75 to 12.3 angle of view, a 28300 mm (or an 18200 mm for an APS DSLR) has an 11.1x 75 to 8.2 Nov 20, 2011✓
