Product Description
The Tamron 18-250mm is great for macro photos, too, with a maximum magnification ratio of 1:3.5 letting you fill the frame with a subject approximately the size of a business card. As a result, you can easily and conveniently enjoy close-up (macro) photography of flowers, insects, and more. Tamron has also adopted various countermeasures against ghosting and flare, common problems in digital photography. The lens employs internal surface coating and new multilayer coating technology to minimize reflections that occur when light enters through the front element, while also reducing image-degrading effects caused by the imagers themselves.

| In Depth | Tamron's high-power 18-250mm zoom lens is a photographer's dream come true. While conventional 35mm film cameras typically require two lenses to cover 28-388mm, the Tamron 18-250mm lens does it in one, with a 13.9x zoom level delivering enormous photographic freedom in a single compact housing. The life of a digital photographer has never been better. Despite achieving the ultra telephoto capabilities of a 388mm lens (35mm equivalent), this Tamron zoom lens sports an extremely compact optical system. Unlike previous Tamron lenses, the lens optimizes the power distribution of the entire optical configuration without using XR glass, letting you achieve both ultra-high-power magnification and a minimal size. In addition to offering low dispersion (LD) glass to eliminate chromatic aberration and sharpen ultra-long shots, the lens offers such special materials as hybrid aspherical elements and anomalous dispersion (AD) glass to achieve three goals at once: increased magnification, compact size, and improved image quality. |
