The GT-1 40mm Telephoto 1.43x Conversion Lens from Ricoh provides your GR DIGITAL and DIGITAL II cameras with 1.43x magnification, which makes it better suited for shooting from far away. Whether you're shooting wildlife, portraiture or sports the GT-1 zooms-in on the scene and allows you to get more close-up detail into your frame - simply attach the conversion lens and start shooting. Just be sure to have the GH-2 Hood and Adapter required by this conversion lens for both cameras, as well as turning off the built-in flash to prevent unwanted vignetting in images.
Having 1.43x magnification means your focal length will be transformed to the 35mm equivalent of a 40mm lens - zooming-in your camera's field of view for a closer perspective.
A firmware update is required to use this lens with the GR DIGITAL camera, while the GR DIGITAL II is compatible right out of the box. The GH-1 Hood and Adapter are required to use this lens for both cameras, and the built-in flash cannot be used with this lens as vignetting may occur.
