IF (Inner Focus)
To ensure stability in focusing, this lens moves the inner lens group or groups without changing the lens' physical length.

ASP (Aspherical Lens)
The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.

DC (DC Lens)
These are special lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus ! including compact and lightweight construction.

17-70mm f/2.8-4.5 DC Macro

Large aperture standard zoom lens designed specially for digital SLR cameras.

The lens is ideally suited for a wide variety of subjects and is designed specifically for digital SLR cameras featuring APS-C size image sensors.

A lens specially designed to suit the characteristics of digital cameras
This revolutionary lens has a minimum focusing distance of 20cm (7.9”) throughout the entire zoom range. A maximum magnification of 1:2.3 enables extreme close-up photography. An impressive achievement for a standard zoom lens. The new lens design and multi-layer lens coating reduce flare and ghosting, a common problem with digital cameras.

The advanced design has resulted in a compact and lightweight lens
A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range. This lens offers a large F2.8 aperture at 17mm wide angle and yet it is compact, with an overall length of just 82.5mm (3.2”) and diameter of 79mm (3.1”). Performance is superb, even in relatively low light conditions indoors or at dusk.

Inner Focus System
The lens is equipped with an inner focusing system, which prevents the front element from rotating making it particularly suitable for petal shaped hoods and circular polarizing filters.

Zoom Lock
The lens is also equipped with a zoom lock that eliminates "zoom creep" during transit.
