The Pentax Optio S5z, a 5 megapixel compact camera with a 1/2.5-inch CCD, 3x zoom, and a 2.5-inch LCD, is the smallest camera in Pentax's Optio S line at 3.3 x 2.2 x 0.8 inches and 4.2 ounces. It's also the most expensive, with an MSRP of $349.95, though online prices range from $270 to $350. It's about $50 more than Pentax's Optio S55, and about $120 more than the Optio S45.
Like the other cameras in the Optio S line, the S5z is clad in a bright aluminum alloy, and features the Pentax Sliding Lens system, which allows the lens to retract fully when the camera is shut off. Also like other cameras in the S line, the Optio S5z is very easy to use. Pentax's slogan for the cameras is in fact, “No experience required,” and they deliver.
