Maintaining the high performance of the previous model, Tamron's 28-300mm f3.5-6.3 XR DI LD Lens now features the Tamron "Di" design, making it the ideal lens for use with both full-frame and consumer digital SLR (APS-C) formats. This all-in-one, compact zoom lens offers a minimal focusing distance of 0.49mm and a versatile focal length that covers wide-angle use and subjects at a distance, such as wildlife, sports and portraits.

The Tamron 28-300mm Lens Overview
Di (Digitally Integrated)
Is the designation Tamron puts on lenses featuring optical systems designed to meet the performance characteristics of digital SLR cameras as well as film cameras. These lenses may be used on cameras with full format (FF) or APS-C sensors (with a crop factor relative to the camera).
XR Glass is a special type of glass with a high index of refraction. XR Glass allows for a more compact lens construction in terms of length and diameter, as compared to a lens made of customary glass with the same luminosity and optical performance. The focal length of an XR glass element is shorter than that of customary glass, so that the barrel of an XR lens can be shortened. As a result of the shortening of the barrel, the actual opening consequently becomes bigger and the lens diameter can also be reduced (see picture). The luminosity of the lens remains the same in spite of the smaller diameter.
LD Low Dispersion
LD Elements are produced of special glass materials which possess an extremely low color dispersion index (a unit which measures the ability of a glass to separate a beam of light in its spectral colors). LD elements compensate for chromatic aberration, which is particularly a problem with telephoto lenses. Chromatic aberration is a form of optical noise which reduces the sharpness and the brilliance of an image.

Top notch purchase!

About Me Hobbyist/Enthusiast
Comments about Tamron 28-300mm f3.5-6.3 XR DI LD Lens - Pentax Fit:
Love photography but prefer to travel light so having one lens that does wide angle, telephoto and macro all in one is ideal for me and my camera. I use it for landscape and macro nature photography and output so far has been great!
Bottom Line Yes, I would recommend this to a friend

Great all round lens, and easy to use
By Mary B
I use this lens mainly for wildlife shots using the 300mm zoom, but having the 28mm facility makes it is so versatile for use in landscape and portrait photography. Its lightweight and small, a great travel lens for those holidays when you don't want to carry a lot of equipment.
