The Canon LA-DC58K Lens Adapter allows users to add the TC-DC58D Teleconverter to the Canon Powershot G10, G11, and G12 digital cameras.
The adapter can be taken apart into a front and back component, but both parts are required for use with the teleconverter lens.
Note! Although the adapter has 58mm threads, attaching a 58mm filter might cause vignetting.
