The PowerShot Pro1 is a digital 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 the professional lines of their FD, EF, and RF lenses for interchangeable lens cameras. It has a variable-angle two-inch, polycrystalline silicon, thin-film transistor, color liquid crystal display with approximately 235,000 pixels and a colour electronic viewfinder (EVF) with the same resolution. The lens has a zoom range of 7.2 to 50.8 mm, equivalent to 28 to 200 mm in 35 mm terms. The shutter has a maximum speed of 1/4,000 second. The camera's dimensions are 117.5 mm in width, 72 mm in height, and 90.3 mm in depth. Its mass is 545 g.
