LAH-DC20 and LH-DC40

Conversion lens adapter and lens hood set

The LAH-DC20 is an adapter that lets you mount conversion lenses or 58mm filters to your Canon PowerShot S2 IS, S3 IS, or S5 IS. Provides a 58mm filter mount for adding wide angle and telephoto conversion adapters, filters, and other accessories.
The LH-DC40 lens hood attaches to your camera and shades the lens, minimizing flare and ghosting from stray light.
