Maria Sharapova was the special guest of honor when she unveiled the Canon PowerShot Diamond Collection on August 20. She wore a unique dress with a single black sleeve on this memorable occasion. The new camera is a limited edition camera specially designed by Canon. Each Canon PowerShot SD 1101 is embedded with 88 white diamonds around its lens. Six models were dressed to look like Maria Sharapova and they mingled freely among the guests to pose for photographs.
