The traditional cameras that used a whole lot of apparatus for capturing images have evolved into compact multi function, feature rich digital cameras of modern times. With technology and innovation, digital cameras have been getting more advanced with the release of each new version. These technological innovations look at making the gadget more sophisticated with high tech features and simpler in use by easing the use of complicated technology. One such camera, the focus free camera aim to enrich the photography experience of novice users.



What is a focus free camera?

A focus free camera is the base version of a . The camera's design enables the camera to capture a picture that is within focus in a certain range of distances. This essentially means that in a focus free camera you do not need to adjust the focus. The higher version of a focus free camera is the auto focus camera that automatically adjusts the focus of the camera according to the picture and the light conditions. The focus free camera has the obvious cost advantage over other cameras and is a great choice for beginners.

Many a times the fixed focus cameras are also included in the category of focus free cameras because the fixed focus camera also does not allow the user to set the focus before shooting.

The mechanism of an auto focus camera is controlled by a mini motor that is further controlled by a computer program to focus the camera lens. The lens of the camera keeps adjusting itself until the object comes into the sharpest possible focus, which is also dependant on the distance of the object from the camera lens. This requires the auto focus camera to calculate the distance between the object and the camera lens.

In a point-and-shoot camera, the camera determines the distance between the object and the lens of the camera by emitting an infrared signal that detects the distance. An auto focus camera works best within the distance of around 20 feet.

Before these cameras were introduced, photographers were dependent on adjusting the lens of the camera manually to get the object in focus. Besides the obvious benefits of cost, the focus free cameras are a boon for people with eyeglasses and of course for beginners who are not ready to wander in the technicalities of a camera focus. So now you can get the benefit of capturing the moment as and when with losing it trying to set focus.
