    Cons: - Very strong field curvature - You need to stop down to f/8 or focus manually to get edge to edge sharpness - Autofocus not 100% reliable - Lens is quite big for mft cameras

    Pros: - Good build quality - Nice bokeh - Very good sharpness in the center from f/1,4 - Fast autofocus - Affordable price

    Summary: This lens is a mixed bag... It\'s big but not heavy at all. Seems quite well build with a large manual focus ring. I found it very nice for portrait since it has good sharpness in the center even wide open and bokeh looks overall smooth. However, it has strong field curvature ad edge to edge sharpness was deceiving unless you stop down to f/8 or focus manually. I don\'t agree with the review saying it is almost equal to the 25mm f/1,2 pro. I upgraded to this one and find it way better. The Sigma is still a good lens and a bargain for the price but don\'t expect it to beat a 1200$ lens.
