The Nikon PB-6D Bellows Spacer enables moving a Nikon F6, F5, D2 series or D1 series on the PB-6 Bellows Focusing Attachment rail without interference. It also allows horizontal/vertical changeover anywhere along the rail. Two PB-6Ds are needed with the PB-6; three are needed when using the PB-6E Extension Bellows.
Note! D3, D700, and D300 may require PB-6D depending on camera orientation

Comments about Nikon PB-6D Bellows Spacer:
Used on PB-6 Bellows with Nikon D-3. It works as advertised and allows the clearance necessary to work with Nikon cameras with motor drive. Only issue I have is that you still need an extension ring on the camera to give clearance necessary to mount the camera to the bellows. This limits the magnification limits on the low end.
