Waterloo, Ontario, December 1, 2005 - DALSA Corporation (TSX:DSA), an international high performance semiconductor and electronics company, today announced that its customer, Mamiya, has set a shipping date for its new Mamiya ZD medium format camera. The professional grade camera, which integrates DALSA's 22 million pixel image sensor chip, will be available in Japan on December 21st, 2005, and will be released world-wide in January 2006.

The Mamiya ZD is the world's first medium format digital SLR camera that is both fully integrated and portable. Medium format cameras are used extensively by commercial photographers for advertising, wedding, portrait, and landscape work. Compared to the smaller 35mm format, the imaging area on a medium format camera is two times larger, providing sharper, higher quality images with significantly more detail. As in other areas of photography, medium format is rapidly transitioning from film to digital. The move is being fueled by the availability of viable digital camera and workflow solutions that allow commercial photographers to eliminate film costs and significantly increase productivity.

"We are very pleased that Mamiya has incorporated our 22 megapixel sensor into the Mamiya ZD," commented Brian Doody, President of DALSA Digital Imaging. "Our image sensor technology and product roadmap allow Mamiya to gain a strong performance advantage. We're fully prepared to meet the anticipated strong demand for the Mamiya ZD."

"We appreciate being supported by DALSA as a key supplier in the development and introduction of the Mamiya ZD camera," said Mitsunori Takizawa, President of Mamiya. "Combining Mamiya's optical technology and DALSA's leadership in digital imaging technology allows us to differentiate our new camera product in the professional digital photography marketplace."
