 Canon A620 - DIGIC II processor
The DIGIC II can be found in both the professional range, which includes the EOS 1DS Mark II and the amateur range to which the A series belongs. Among other things, the fast processor enables you to start up quickly and has a very fast shutter release and rapid image processing. In fact, this small feature accounts for Canon's manifestly large share of the market. Canon is able to incorporate innovative developments from its range of professional cameras into the amateur range within a short period of time and in doing so, it clearly stands out as an innovator.
Canon PowerShot A620 - Focussing
The addition of Canon’s advanced DIGIC II image processor results in a faster and more responsive camera that delivers improved image quality. Focusing time has been cut by around 60%, and shutter lag is negligible at no more than 0.1 seconds. Smooth continuous shooting is now available at approximately 1.9 fps for the A620. With DIGIC II’s superior assessment of white balance, colour rendition accuracy is increased. The new PowerShot A620 features Canon’s 9-point AiAF for fast, accurate focusing even when subjects are not centred. FlexiZone AF/AE allows free scrolling anywhere within the frame's auto focus area to select the desired subject, for which exposure is weighted accordingly. Manual focus selection is also available.
Canon A620 - Optical zoom lens
Precision Canon zoom lens in this new A620 Powershot camera follows the design and construction of G-series lenses, with eight elements in seven groups, and incorporating two aspherical elements. The upgrade to a 4x optical zoom provides a 35-140 mm focal length (35 mm equivalent). With a maximum aperture range of f/2.8 (W) to f/4.1 (T), the lens is impressively bright at the telephoto end. In addition, focusing performance in low light has improved by up to 2-stops, resulting in greater freedom when shooting in dim conditions. The lens’ spectral characteristics has been optimised specifically for the configuration of the lens and sensor, providing accurate colours and significantly reducing the chromatic aberrations (such as purple fringing) often found with lower quality lenses.

Canon PowerShot A620 digital camera review : Canon has found a formula for success with the PowerShot series of digital cameras. The concept of a wide range of functionalities and advanced features with a low entry-level for users has really caught on, and it is with good reason that the PowerShot A series of cameras is popular with Canon users. The Canon PowerShot was officially introduced in 2005, replacing the Canon A95 and raising the resolution to 7 Megapixels simultaneously. One of the differences to its predecessor is the format and flexibility of the screen at the back of the camera; it has been enlarged from 1.8 to 2.0 inches and can be tilted.
