Macro bellows are a great accessory for close-up, macro, micro, stereographic, slide/negative copying, and panoramic photography. The precise rack and pinion gear allows very minute fore and aft movement of your camera set-up for very accurate focusing. The bellows has a locking screw to ensure it does not slip when pointed up or down. The bellows can accommodate heavy cameras and lenses. Any camera with the appropriate adapter can be used with the bellows. The bellows can be mounted on a copy stand, tripod, light stand or any accessory that accepts a ¼" tripod screw. It can be used outdoors for great nature close-up photography, due to its compact size and light weight.
