Excellent lens for the price!
2 of 2 found this helpful I scored this lens super cheap and am really happy with it! Nice color and contrast and center is very sharp from f2. Whole image is razor sharp from f5.6. I am using this lens on a Sony Nex 5n which is APS-C so I don't see the actual corners of the image though. Build quality of this lens is A+, smooth focus ring and aperture clicks. Wide open at f1.7 everything is pretty soft but the center is still sharp enough for portraits. If you shoot wide open at anything strongly lit you will get ghosting and CA but this can be used for artistic effect. Also bokeh when stopped down is hexagonal so that may be a con for you if you like creamy bokeh. Overall I highly recommend this lens.
