The LEICA DG SUMMILUX 9mm F1.7 is comprised of twelve lens elements in nine groups including two aspherical lenses, two ED (Extra-Low Dispersion) lenses and one UHR (Ultra High Refractive Index) lens to effectively suppress both axial chromatic aberration and chromatic aberration of magnification. Astigmatism is also corrected with these aspherical lenses, achieving high resolving performance. Furthermore, a UHR (Ultra-High Refractive Index) lens achieves uniform image quality from the center to edges of the image while contributing to downsizing of the lens unit. The filter diameter is 55 mm, with a 7-blade circular aperture diaphragm.

It is a bit strange because in case of full frame you see more and more 20-21 mm f/1.4-1.8 models. A system with a sensor two times smaller should also offer equally fast devices with angles of view approaching 100 degrees.

Among them, only the Voigtlander has a really good aperture fastness but it also provides the narrowest angle of view and, additionally, it proved to be the weakest of the whole Nokton line designed for the Micro 4/3 system. The Meike and the Laowa don't impress us with their apertures for a change.
