Just so you know biases, I love fast aperture lenses and have owned several for multiple camera systems, including Canon, Nikon, Leica (Voigtlander), Panasonic and Sony. This 45/1.2 completes my set of Olympus f/1.2 PRO lenses and so far I'm quite pleased with the wide open performance. Very good resolution and none of the residual spherical aberration that often plagues fast lenses. Fast AF and beautiful finish like it's sisters 17/1.2 and 25/1.2. I consider all 3 to be suitable for portrait and street photography...for that matter any kind of photography. Hope the attached photo isn't dithered by eBay and does the lens justice. The original photo is bitingly sharp.
