I just got it in the mail today. I pulled the trigger last Tuesday, the seller sent it within about two hours of me paying (granted, Australia and Japan only have an hour or two different, may be different if you are in vastly different timezones), and provided me with a tracking number. The tracking didn't help much, I guess whoever was handling it wasn't too diligent about updating the tracking as I've got entries tracking its departure from Japan and after it left Melbourne the tracking stopped. It took my girlfriend coming back home to find it by my door to bring it to my attention, I was expecting a personal delivery. But that says more about the Australian postage system than anything else, so I can't fault the seller for that.
As for the lens itself, I present to you the unboxing:
The package
The side view where there has been some dents, probably at the airport
As you can see, the actual box itself is very well cushioned with wrapping paper
... and also bubble wrap
A brand new lens inside the box
The actual lens itself
Everything works, the shutter fires properly and there's no fungus, the lens is like factory new, it's pristine and there is no fungus on the lens. If I didn't know better, I'd think that this lens was made fairly recently, I think Mamiya still has a limited production of new lenses?
I'm going to take this baby to the beach later today and run a couple of rolls through and put this through its paces.
