The Schneider Super-Angulon XL 58mm f/5.6 is a wide-angle large format lens producing an image circle of 166mm, covering 4x5in format with some room for movements. At 320g with a 67mm filter thread, it offers a practical balance of wide coverage and portability. The XL series features aspherical elements for enhanced image quality across the full field, and the 110-degree angle of view makes it a popular choice for architectural and landscape photography.
