DESC: The PZ40X combines high-performance features with innovative design. The unique rounded angles and low-profile provide a more functional design and is the perfect match for current digital and photo cameras. While compatible with the latest E-TTL (Canon), 3D D-TTL (Nikon) and ADI (Minolta) functions for 35mm digital and film SLR cameras, power-ratio and zoom setting can also be controlled manually in 5 steps.
