The Tamron compact lightweight, high-image-quality Di type zoom telephoto lens with 1:2 macro capability that can be mounted on digital cameras. This lens uses an with an improved multi-coating optical system created to work with both film SLR and DSLR cameras. This lens favors outdoors where there's lots of light.
Flipping a switch for macro while in the 180mm to 300mm focal length range gets you a maximum magnification1:2 ratio at a minimum focusing distance as close as 37.4", letting you capture close-up images of insects, flowers, and other subjects that normally require using of a specially created macro lens. Furthermore, it's a zoom lens which nonchalantly provides the distant foreshortening acquisition enjoyment of a 300mm telephoto zoom world.
If you need a low light lens, this isn't it. If your primary objective is to take pictures in poor light situations such as concerts and weddings, then get the Tamron 70-200mm f/2.8 Di LD (IF) lens instead. The overall contrast is only average at best, although I never felt it is deficient. Just not overly 'WOW' like a few prime lenses are. There's scarcely any lens distortion up for discussion, however chromatic aberrations beyond 200mm can be seen sometimes, although easy to fix with Photoshop and the focus speed is average to slow.
