Just tried twice to buy a used Fuji XF 2.4 60mm with 12 months warranty and failed due to some sort of 3d security system process? Really peeved about this as I ended up going to Clifton Cameras as a consequence, to purchase the same item, using the same security system, without any issue or problem at all? Unfortunately Clifton only offer 6 months warranty on a "mint" graded item.
