It's amazing how sharp the Sigma 50mm f1.4 is at f1.4 ... once you manage to nail the focus that is ... which for me is not that easy.
I believe the focus shifts a bit with the aperture, so even a calibrated lens can benefit from a bit of manual fine-tuning. The lens is otherwise well described with a WOW, and on my 1.7 crop SD15 even the corners are sharp wide open.
