Philippe, I may have a bad copy of the planar, but at 1.4 I can\'t expect better sharpness from mine than what you show in your crop.
The lens surely creates a dreamy \"glow\" wide open, as someone has said, but it\'s very far from sharp. At regular image sizes it\'s hardly a problem, though. It\'s not a focusing problem since I can track the focus point on some ground in the picture, and even at this focus point the image is very soft despite good shooting parameters (ie. iso, speed, etc...).
I can\'t get very good sharpness until the aperture is closed to f2.5.
I knew this before I buyed the lens, as this lack of sharpness is somewhat of a strength for some shots.
