Main features: The main features of a telephoto digital camera are actually similar to the principle of a telescope. hunting trail camera,The focal length is changed by the movement of the lens inside the lens. The benefits of telephoto come into play when people shoot distant scenes or when the subject doesn’t want to be disturbed.
In addition, the longer the focal length, the shallower the depth of field, which is the same as the effect of the larger the aperture, the shallower the depth of field. The advantage of a shallow depth of field is to highlight the subject and blur the background. The longer the lens of a digital camera, the more space for the internal lens and photoreceptor to move. large, so the zoom factor is also larger.
