Nikon PB-5 with PS-5 wide angle is pretty decentThe Nikon PB 5 is a well made macro bellows with a rigid two rail design. Accepts any Nikon F mount lens; the camera end is a standard F mount but practical compatibility will depend on the shape of your camera (some bulkier AF and digital cameras will require an additional extension tube not included to clear the back of the rail). Some cosmetic wear, including light corrosion on rails which does not affect function. Includes PS 5 slide copying
