Description — AstrHori 40mm f/5.6
The AstrHori 40mm f/5.6 is a manual focus prime lens purpose-built for medium format camera systems. With a fixed 40mm focal length sitting in the standard range, it offers a natural perspective well suited to a range of photographic subjects. The f/5.6 maximum aperture keeps the lens design compact, contributing to its impressively light 333g body weight — a genuine advantage when shooting with medium format equipment that can otherwise be bulky.
