Canon EF 25mm Lens Extension Tube II
- Shortens focusing distance of lens
- Compatible with EF-S lenses, as well as EF and TS-E lenses
The Canon EF 25mm Extension Tube II is used to allow a lens to focus closer than it does natively. This is accomplished by moving the lens 25mm farther away from the camera body's sensor/film plane by fitting between the camera body and the lens.
