Thank you for viewing. Fisheye Ultralight Clamp Series Clamp SD, set of 2. According to the manufacturer: ・Retail price: ¥5,830 (per piece) ・Effective length: 40mm Condition: ・I forgot when I purchased them. ・There are scratches and signs of use. ・I don't think there's much deterioration of the material itself. ・There's some catching, but there are no problems with use. ・Compatible with housings, strobes, and lights from various manufacturers. ・Tightens strongly, so it's recommended for the base adapter side.
