I Never Felt it Deficient.
Just Not Overly 'WOW'
Tamron 70-300mm F/4-5.6 AF Di LD Macro Lens
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.

DI - Digitally Integrated Design
ghosting, flare, CA and peripheral light fall-off along
with improved resolution of the optical system to meet
the performance characteristics of digital SLR cameras
as well as film cameras).
• Built in Motor for Nikon
This version has a built-in Motor which will allow it to work with all Nikon Digital Cameras. With some Film cameras this will not work in Auto Focus mode
• Low Dispersion lens elements
Glass to reduce
chromatic aberration for sharper images) Aspherical - contains aspherical elements (compensates for
spherical aberration and
distortion, making for better performance with fewer elements (and As a result allowing for smaller, lighter lenses)
