Pentax SMC-m 50 f1.7 vs Konica 40mm

Just wondering if anyone knows how the Pentax SMC-m 50 f1.7 compares in image quality to the Konica 40mm f1.8? Im looking for a legacy lens for the Lumix gx1.

Pentax is sharper, among the best, while konica is smaller, lighter, cheaper, but some less good at wide open.
From f5.6 hardly see any different. There are many good 40-45-50-55 in this class.
