    All shot are shot with JPEG, AWB (pardon for inconsistent WB) with Olympus EP1.
    No other processing besides resize.


    Distance of scale for reference on apperture testing. The closest subject (doll on the right) to furthest subject (招财猫) is approx 10inc.

    The Summilux optical quality give a very sharp output.
    Now look at the center vs 100%, and corner at 100% crop.

    Bokeh
    Only one comment, Sweet ! Besides of Nokton f0.95, this is m4/3 largest aperture AF lens. f1.4 allow good indoor shot. (indoor/lowlight field test in next thread)

    Optical Quality
    Very sharp. I have not shot with Leica Summilux/summicron mounted on m4/3 cam before, but up to date, this is the sharpens m4/3 fens I have used. It is certainly a mile ahead of Panny 20mm f1.7

    Corner Sharpness
    Have not done pixel mapping or MTF chart. But based on eye ball judgment, the corner performance has held up pretty well. Only at the 3-5% corner, you would see some softening.

    CA
    Very well controlled and hardly noticed. In extreme conditions, there is only small amount of purple fringe.

    AF
    Though mounted on first m4/3 camera EP1, the focusing is pretty fast. I have also tested this lens on GF3 and EP3, the AF is almost instant. Hardly imagine how could the AF can further improved. However, similar to Lumix 20mm f1.7, it has some unpleasant motor sound when the apertures move during focusing.



    Below is the field test on low light shot ;

    I would believe if it is on EP3 or GH2/GF3, it would be able to draw more detail/resolution from the lens.
