Lens looks nice. But it has couple problems. First, auto focus is very stiff, so lens is not auto focusing. But it can be used in manual focus mode. Focus is still smooth, just too tight for auto focus. and second problem is aperture blades don't spring back. It seems that spring is damaged. But aperture can be adjusted manually, using aperture ring. On digital cameras that would cause FE error. Still lens can be used in M mode. So it still works in manual focus and manual aperture modes.
