if thats the way it looked when it arrived, something went horribly wrong in shipping, AP would never ship a lens like that

1) talk to AP, get RMA #

2)pull the three socket head cap screws (dont touch the set screws)

3) lift lens off

4) wrap in tissue paper and then box safely... this is an idea of what safe lens shipment looks like

5) send to AP
