Speed Of The Focus

The focusing speed of a digital camera is the delay between the zoom setting of the photographer and the actual finding of the focus point by the AF system.

In short: It's about the milliseconds between pressing the zoom lever on the camera body and a really sharp image in the viewfinder. As is often different factors influence on this very important measure. This is the first type of autofocus system: A different frame AF, for example, by the video autofocus. Furthermore, many modern digital cameras now distinguish between characteristics such as pursuit-phase detection autofocus or auto focus.

The number of lenses in the optical system and the focal length of the lens have a massive impact on the focus of your digital camera. On the "last mile" will decide the vision - here, among other things, the image processor - to be or not while focusing the image scene. Who, for example, used a telephoto lens is a AF motor can focus much quicker than with the venerable mechanical transmission.

Although the autofocus performance a significant factor in the quality of regular use of digital cameras is that they are underestimated by less experienced users often. This is nothing more annoying than a slow focusing camera: spontaneous capture images in the course of this rare and the use of the device range is limited accordingly bad.

Although there is no clear correlation between price and digital camera auto-focus performance, can still be said unequivocally that low entry-level compact cameras focus on average slower than devices of the middle and professional class. The frequently used video-AF is much slower than phase detection system.

Beginners lost amid all the technical terms, often the fact that ultimately decides the scanned location of the actual achievable focusing speed: Scenes with little light or too uniform color spectrum for a digital camera to process significantly more difficult than colorful images of nature under ideal conditions, the midday sun. Also, back light, dramatic example, by a lamp, slows down the autofocus in places or even places him out of action.
