F2014 16 MP DIGITAL CAMERAS LENSES
The lenses used in most professional camcorders are zooms. This means that the focal length can be changed during recording. The requirements for a professional camcorder are very high to ensure that the image never distorts at all focal lengths. The design of the lens is very complex and sophisticated. Its characteristics are the most important influence on the impact of the image.
Zoom range
The lens is usually defined as follows: zoom range X minimum focal length. The minimum focal length tells us whether the lens is a telephoto lens or a wide-angle lens, which generally corresponds to a distance of about 7.5 mm. Some studio lenses can be very wide and still have a large zoom range. These lenses can be used in almost any situation.
The zoom lens allows a faster work mode than the main lens. Sometimes it's easy to forget the focus distance you use during recording.
Preceding focus
The flange focal length adjustment ring controls the rear focus lenses, ensuring that the subject is in focus during zooming. This setting is called the last focus setting and must be set correctly when preparing the camera or changing the lens.
A good lens is designed to keep the subject focused on the entire zoom range. However, for this to be the case, the subsequent focus needs to be properly adjusted. If you zoom in on an object, focus on it, then zoom in and see that the image becomes unclear, and its focus later is not correctly set or changed during production.
