Three new ones from Pentax: The Optio S5z, the Optio S55 and the Optio S45

Three new digital cameras from Pentax today:

The Optio S5z, a new ultracompact five megapixel camera that's just 3.3 x 2.2 x 0.8 inches in size and weighs only 3.7 ounces and that sports a 2.5-inch LCD screen and a 3x optical zoom lens. Retail price will be somewhere south of
$350.

The Optio S55, a compact five megapixel model with a 3x optical zoom and a 2.5-inch LCD screen. Will retail for under $300, so it sounds like the S55 is mainly for people who don?t want to cough up an extra $50 for the smaller S5z.

And rounding things out, the Optio S45, a compact four megapixel camera that has a 3x optical zoom lens and a 2.5-inch LCD screen. Should sell for around $230.
