This sale is for a very hard to find pair of Fuji GX680 80mm extension rails in mint condition, suitable for use on all of the GX680 cameras.
This is an invaluable accessory for any Fuji GX680 camera user. These rails allow better than 1:1 macro images when used with a 100mm lens. They must be used in combination with the long bellows.
These rails are have absolutely minimal signs of use – very very little used. The marks on the rods that go inside the tubes were probably there from manufacturing; I have seen brand new extension rails with similar markings.
