I'm selling my MAMIYA 645 AF Auto Extension Tube model NA403. This tube will go between your lens and camera body to allow you to get greater magnification and allow you to focus closer.
It is in perfect working and cosmetic condition.
Asking for €90 or $100. Price includes Paypal fees.
Shipping (worldwide) with EMS and insurance: €30 or $35.
I have also Phase One P65+ digital back for sell.
