You are bidding on a Viltrox 15mm f/1.7 Air lens for the Fuji XF Mount system.  This is part of the Viltrox Air lineup of lenses which are small and light, have a low aperture, but still give you amazing picture quality.  This comes with the lens hood, both caps, the cloth carrying bag, and the box (however, the box is actually the box to my Viltrox 56mm 1.7 Air - I cannot find the 15mm's box).  I love the compact size and light weight.  It makes my camera easy to handle and doesn't give my wrist any fatigue.  The picture quality is sharp and holds up well with my 40mp camera.  The autofocus is quick and quiet.
