The Hungarian website Index Digicam have reviewed the Sunpak PZ40X Flash in conjunction with the Canon Powershot Pro1 digital camera. The Sunpak PZ40X is a powerful, full-featured, lightweight, shoe-mount electronic flash unit for digital and film cameras, that is available in Nikon, Canon, and Minolta TTL dedicated configurations, and will also work manually with cameras having a non-dedicated, single-contact hot shoe. It is 40% smaller and significantly lighter than previous flash units with the same features and power output: with an impressive guide number of 102 (ISO 100, ft) at the 50mm zoom setting.
