The PowerShot Pro1 is a igital camera made by Canon, announced in February 2004 and was discontinued first quarter of 2006. It uses a Sony-built 2/3 in (17 mm) 8.3 megapixel CCD image sensor, which gives a usable image size of approximately 8.0 megapixels. It was the most expensive fixed-lens camera sold by Canon at the time, and thus the top of the PowerShot range. It was the first fixed lens designated a Canon L series lens, a designation normally reserved for expensive EF-series SLR lenses.
