Olympus 25mm F/1.2 Pro lens is the fastest lens in terms of aperture available by Olympus at this moment. It keeps relatively small dimensions and weight given the large aperture and as it turned out, exceptional build and optical quality. You can find all information’s and test analysis in my Youtube review of this lens. Download links for full resolution sharpness test are below.
