EX-25 is an extension tube for Olympus digital single-lens reflex cameras. It can be used for close-up photography. It features a dust- and water-resistant design and can be used with the ED50mm F2.0 MACRO lens to take photos at an almost equal magnification (0.98×) (equivalent to 2× on a 35mm film camera).
The EX-25 is an extension tube designed exclusively for Olympus Four Thirds DSLR cameras. It offers dust‑proof and drip‑proof construction and enables close‑up shooting with a magnification close to 1:1 when used with the ED50mm f/2.0 MACRO lens.
The manual explains how to mount and remove the tube, safety precautions, and the technical specifications such as weight and dimensions. It also lists compatible lenses and notes that the tube cannot be used with the optional EC‑14 teleconverter or stacked with another EX‑25.
