Power Grip specially designed for SIGMA SD1 PG-31

The Sigma Corporation is pleased to announce the release of the Power Grip PG-31, specially designed for Sigma’s SD1 digital SLR, the camera that ensures high resolution and breathtaking image quality.
The PG-31 is a specially designed battery grip which upgrades the battery power of the SIGMA SD1 by holding two dedicated BP-21 battery packs. This caters for large-volume photography and photography in field. The PG-31 also incorporates a shutter button and therefore becomes a grip for vertical photography when attached to the SD1, providing a more assured grip.
