The polish website Optyczne (Click here) posted their final Olympus 45mm f/1.8 review. In short, this is a MUSTA-HAVE lens! It has a sensational image quality in the center of the frame and an excellent quality on the border. Very low CS, distortion,astigmatism and vignetting. The only minus is that it is not an all metal lens. But damn, it costs you 399 Dollars only! For that price you would be crazy to expect a 12mm f/2.0 quality build quality!
