We've seen a lot of compact megazooms announced this year and, well, here's one more. The 16-megapixel Pentax Optio RZ18 packs an 18x f3.5-5.9 25-450mm lens in a body that's only 4.3 inches wide by 2.4 high inches by 1.4 inches thick. That's roughly the same dimensions as the Nikon S9100, which has a lens with the same specs. It's impressively small given the size of the lens.
Other key features include sensor-shift image stabilization; a high-resolution 3-inch LCD; fast burst shooting capturing up to 40, 5-megapixel photos at up to 9 frames per second; and 720p HD movie capture at 30fps.
You'll also get a full assortment of automatic shooting modes including creative special effects filters, enhanced face and pet detection, and a macro mode that lets you focus as close as 1.6 inches from your subject.
The Optio RZ18 will be available in black, pearl white, or metallic orange for $299.95 in October 2011.
