Standardbrennweiten

Standardbrennweiten, often referred to as normal lenses, represent a category of photographic lenses whose focal length approximates the diagonal of a standard 35mm film frame or digital sensor. This typically results in a field of view that is considered natural and comparable to human vision. The most common standard focal length for a 35mm format is 50mm.

Lenses with this focal length tend to minimize distortion, especially in the periphery of the image. This makes them well-suited for a wide range of photographic applications, including portraiture, street photography, and general-purpose shooting. The perspective rendered by a standard lens is neither excessively wide nor strongly telephoto, offering a balanced view of the scene.

The term "standardbrennweite" is derived from the German words "Standard" (standard) and "Brennweite" (focal length). While 50mm is the most prevalent standard focal length in 35mm photography, the equivalent focal length may vary slightly depending on the sensor or film format's aspect ratio. However, the principle of approximating human vision remains the core characteristic.

The popularity of standard lenses stems from their versatility and ability to produce images that feel familiar and immersive to the viewer. They are often a foundational lens for many photographers due to their ability to capture scenes without dramatic perspective shifts.
