This lens has a fixed focal length, which cannot be changed. Fixed focal lengths offer a high light intensity, which allows you to take good pictures even in less than optimal lighting conditions. They are particularly suitable when you want to capture specific and characteristic parts of the image. Thanks to the large possible aperture, a shallower depth of field can be created. This allows you to optimally expose subjects from the background with the targeted use of sharpness and blur. This lens can only be focused manually. Although manual focusing takes longer and is more demanding than working with autofocus, it does offer some advantages: It allows you to focus on exactly the point you want, enabling you to take shots that are exactly what you want. You also prefer to focus manually in situations where autofocus would quickly become overwhelmed - for example, in low light, smooth surfaces with little texture, or in foggy weather.
