ultrawidelähtöinen

ultrawidelähtöinen is a Finnish term that translates to "ultra-wide-angle" in English, commonly used in the context of photography and optics. It describes a lens with a very short focal length that captures a significantly wider field of view than a standard lens. This allows for the inclusion of much more of the scene within the frame, making it ideal for landscapes, architectural photography, and situations where the photographer wants to convey a sense of vastness or incorporate a lot of detail.

The angle of view for an ultrawidelähtöinen lens typically exceeds 90 degrees, and can often reach 110 degrees or more, depending on the specific lens design and sensor size. This extreme width can sometimes lead to characteristic optical distortions, such as barrel distortion, where straight lines near the edges of the image appear to curve outwards. However, modern lens designs often employ sophisticated corrections to minimize these effects. The short focal length also results in a greater depth of field, meaning more of the scene will be in focus from foreground to background. When discussing cameras, the term might refer to the primary wide-angle lens on a multi-lens system, emphasizing its expansive capabilities.
