The GT-2 Tele Conversion lens from Ricoh is designed for use with the GA-2 Lens Adapter and the GR IIIx digital camera. When mounted, the camera automatically detects the GT-2 as a tele conversion lens and extends the focal length to approximately a 75mm equivalent with the camera's crop mode, or to approximately 107mm in the secondary crop mode.
