I've recently graduated to using Sony's GMII range of lenses, so this 24mm Zeiss is now just sitting around.
It's been well used both in a studio setting as well as outdoors in run n gun situations, and as such it is showing the usual signs or wear and tear that you would expect. The glass is still good, however, and doesn't have any major scratches that I can see (it's hard to photograph lens glass but I've looked closely and all appears good).
It's in full working order and should serve you well for many more years. Great beginner lens for full frame camera users.
