It is a manual lens capable of creating exceptional perspectives and creative distortions. The maximum lens aperture f/2.8 is optimal when it comes to work in various lighting conditions, while maintaining a small and lightweight housing for photographing from the hand. The optimized optical structure (11 elements in 9-gaps) is characterized by a higher light refraction coefficient and reduced chromatic abberation thanks to the use of Hoya ED glass lenses.
