"It is also of a very compact design: measuring only 7mm from the camera body." "Construction type: retrofocus" "its ACV system (Auto Compensation Vignetting) developed by Lux Technoligies insures a homogeneous distribution of the intensity of illumination at the level of the film. The ACV system replaces advantageously the so expensive concentric graduate neutral density filter: The photometric aperture is f/22. Orthoscopic optic, the Panomigon 15mm differs by an almost total abscence of linear distortion, thanks to the utilization of high refraction index glass. The very weak curvature of the frontal lens allows the use of filters and other creative accessories in the standard diameter of 49mm, usually not permissible with current optics." "The internal parts undergo a micro-snadblasting preliminary to an anodic antiflare process.... The lenses, made of SCHOTT and CORNING optical glass of exceptional quality, are manufactured in France with the most extreme precision....." "Each Panomigon 15mm lens is checked with the greatest care, not only on optical test bench MTF, but also by photographic tests with film, means to which Lux Technologies grants a great importance... so can the highest level of quality be reached" "Indisoensible complement of the Panomigon, 15mm viewfinder fastens on the camera body by the accessory shoe. It includes a multi-axis spirit-level quite useful for architecture photography....." Hope this helps.... Regards, Joseph
