I would make sure that the filter is correct. That pic (not sure if its the angle or what) doesnt show that it has a return line..
I thought the same thing. The print is in different spots on different filters though and at the odd angle they took the pic at (probably for flash), you can't see the nipple for the return. As long as it's a real GF432, it has to have it. If not, they'll be getting it back....
