From the Manufacturer

Setting the standard for lightweight long-range zooms

AF70-300mm F/4-5.6 Di LD Macro 1:2

Compact top tele-zoom lens with macro 1:2 function. A high mechanical quality combined with excellent optical qualities are the characteristic features of this telephoto lens. This Di lens can be used on a digital APS-C sized or full frame camera. This lens ideally complements standard kit lenses.

A 'Macro Switchover' mechanism allows a minimum focus distance of 0.95m within the focal length range of 180-300mm. You can fill the entire frame with subjects of apx. 5 x 7cm size, at a maximum magnification ratio of 1:2, ideal for capturing images of flowers, insects and objects of similar size. With its 300mm tele-end the lens guarantees ultimate photo fun.

The designation “Di” (Digitally Integrated Design) marks a generation of lenses, which have been specially adapted to the higher requirements of digital SLR cameras (APS-C and full frame).

Low Dispersion (LD) Glass for Greater Lens Sharpness

Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range).
