    Cons: f1.1 to f1.8 is an optical catastrophy. As you open up the aperture from f2.0 to f1.1, you will see sharpness degrade, CA goes completely out of control and contrast tanks really badly.

    Pros: At f2.0 and above center sharpness is passable even on 20mpx MFT cameras, closing down further improves this a bit (but you wouldn\'t get an f1.1 lens to use it closed down all the time). Very nice build quality.

    Summary: If you want an ultrafast, but usable prime, go for Kamlan 50mm f1.1 MK2. MK2 while substantially bigger and heavier, it\'s optically excellent particularly for its price.

    Cons: - Never sharp except in the center - Not suitable for general use

    Pros: - Good build quality - Average to good center sharpness - Fun to play with depth of field - Good for portraits

    Summary: The lens is quite well build and fun to play with especially for portraits. You can get a surprising amount of bokeh but don\'t expect the f/1,1 to be very useful in low light. There is noticeable glow wide open, gets better when you stop down in the center but the edges will never become sharp. Therefore the lens is not suitable for general use to my eyes.
