Fixed lenses for camera

fix

— lenses with a fixed focal length. The specific value of this distance can be different: a “fix” can be a wide-angle model by 25 mm, and a “station wagon” by 50 mm, and a “portrait” by 70 mm, and even long-range optics by 100 mm or more. However, the exceptions to this list are ultra-wide-angle models (up to 20 mm) and telephoto lenses (over 150 mm), they are separated into separate categories. Anyway, the absence of a zoom lens has a positive effect on the reliability, weight and dimensions of such models, moreover, it is easier to achieve high aperture in them than in optics with a variable focal length. On the other hand, it is impossible to change the zoom level when working with a fix, which can create serious inconvenience in some situations.
