So the person who sold me a Hasselblad 50-110 did about the absolute worst packing job I've ever seen. The lens clearly shifted wildly in the package throughout its entire journey because the box was improperly packed. As I understand it, this lens is prone to problems from improper storage. My concern is twofold. This was a con job to pawn a broken lens off on someone, or the possibility the lens broke in transportation because of this poor packing. I put the lens on my H2 and it seems to be functional, but as I can't just shoot a roll and have it developed quickly, what else can I do to check to make sure the lens is ok and functional?
