Nikon PB 4 Camera Lens Adapters, Mounts & Tubes

Take Close-up Shots With the Nikon PB 4

Bellow systems like the Nikon PB 4 provide a way to produce macro photography shots with your camera and lenses. With a bellow system in place, you can take extremely close-up shots in a short amount of time. Here is some information to consider when looking for a Nikon PB 4 on eBay.

• PS-4 slide copying adapter: This detachable component allows you to make copies of 35mm negatives or transparencies. You can also use this part of the PB 4 to crop and edit film for different shots.
• Accordion bellow: This part expands to increase the focal length of the lens. The bellow is made of a light-proof material to keep external light out.
• Rail system: The Nikon PB 4 is built on a four-rail system that works to expand and constrict the extension range. The PB 4 has an extension range of 43 millimeters up to 185 millimeters and can be controlled with a knob on the side. The rail is marked in millimeters to allow for specific settings.
• Mounts: The PB 4 has two separate mounting screws on each side of the bellow system. One side is responsible for connecting the camera body, while the one on the opposite side will connect the lens.

• Camera compatibility: The bellow system uses the Nikon F Bayonet type of mount and can be used with any type of Nikon camera with this style of mounting.
• Lens options: The Nikon PB 4 can be used with lens sizes ranging from 20 millimeters up to 300 millimeters. This can include some standard types of lenses along with macro lenses for extra magnification.
• Support solutions: The PB 4 can be used with a wide range of tripods and other support options. You should find a tripod that has the standard mounting options.

Both bellow systems and extension tubes can be used to take close-up shots with your camera. The PB 4 bellow system increases the focal length by turning a dial to move the rails to the open and close positions. These rails will stretch out the bellows to increase the distance between the lens and camera body. Extension tubes consist of metal or plastic tubes that are attached between the camera body and lens. To increase the focal length, different extension tubes can be added. Some systems allow multiple extension tubes to be connected to each other for an additive effect.
