This is made possible by a second zoom group of lens elements that shifts rapidly to correct for the slightest of hand movements.

The use of Special Low Dispersion (SLD) glass accompanied by aspherical lens elements not only compensates for a variety of aberrations, but also allows for a more compact size.

The new lens consists of 10 elements in 7 groups, including 2 aspheric and 3 extra low dispersion elements, and a seven-blade rounded diaphragm.

This means the rear lens elements are as close as possible to the sensor, reducing the back focus distance of each lens to the minimum possible, thus achieving high resolution from edge to edge.

CDM's imaging system, it passes first through conventional optical elements, and then through a lens moulded into a shape of a cubic-like function (ie, with a surface which, instead of being spherical, is relatively flat in the centre but has scalloped edges).

With three glass lens elements in three groups, it can be used as a wide-angle lens equivalent with a single focal length of 30mm (35mm camera equivalent).
