    Cons: I has a bit of LoCA, but its not a substantial issue. Price.

    Pros: Exceptional optics wide open, weathersealing, MF clutch, consistent size and weight with other f1.2 primes.

    Summary: The king of the hill for portrait primes in M4/3. Nocticron varies too much between copies.

    Cons: - Price - Aperture not fully rounded when stopped down - Could have focus closer

    Pros: - Great build quality - Fast and silent focusing - Razor sharp from wide open - Extremely smooth bokeh at f/1,2

    Summary: This is a near perfect lens. Solid build quality and fantastic image quality. The first sample I got was a bit soft at f/1,2. I wondered if it was normal for a portrait lens but for the price paid, I finally asked for a replacement. I\'m glad I did it, the new one is probably the best lens I\'ve used, with the equally great 17mm f/1,2. Build quality is similar to the other PRO lenses. Focusing is fast and accurate. The lens is razor sharp from edge to edge wide open, I was blown away. Stopping down to f/1,4 or f/1,8 you gain a bit of contrast but the lens is made to be shot wide open. At f/1,2, feather bokeh looks beautiful. At f/1,8 and below, the PRO lens is pretty similar to the much cheaper 45mm f/1,8 even if it\'s a bit sharper. It is expensive for an equivalent 90mm f/2,4. But I think it\'s worth it if you are a portraitist or need a fast telephoto with swallow depth of field. It\'s amazing. Bokeh is smooth and creamy with outstanding sharpness, probably one of the best glass in micro 4/3. I strongly recommend it if you want to upload your gear to another level. But if the f/1,8 aperture is fine for you, then stick with the smaller lens since it\'s a bargain for it\'s price. Would be perfect if it could focus a bit closer althought it\'s quite good for a 90mm equivalent.
