This bayonet has saved me 200 Euros ... the price announced by two photos of stores (Fnac and Photoshop) The disassembly / assembly was conducted in 15 Minutes. which takes the most time is to position the screws that you remove the diagram you have been careful to make before disassembly using the new bayonet. A little patience, two good precision screwdrivers (Phil and Ph 00 000), a good lamp and voila. It really is not worth the shot to go through Nikon. youtube video is a great help. Good luck to all
