The Manfrotto 681B is a photographic support accessory, specifically a monopod, used to steady cameras and lenses during handheld shooting. It is part of Manfrotto's broader range of tripods and monopods aimed at enthusiast and professional photographers.

Sales data for the 681B is extremely thin: a single UK auction hammer result from March 2023 saw one sell for £12. With only one data point at saleroom level, today's market value is best treated as a guide rather than a firm figure, and condition, completeness, and the presence of the original head plate will materially affect what an example sells for.
