We haven't had a chance to fully test this product yet, but we've assembled this helpful overview of relevant information on it.
The Ricoh PX integrates a 1/2.3″ 16-megapixel CCD image sensor, a 5x optical zoom lens, and a transmissive, 2.7-inch LCD monitor with 230k-dot resolution. 720p HD (1,280 x 720) video capture is enabled on the PX, allowing users to shoot at up to 30 frames per second. The power supply on this device comes courtesy of a DB-100 rechargeable lithium-ion battery. Storage is provided via 40 MB of internal memory, while an SD/SDHC card slot allows for expansion with external media.

Digital Trends’ Camera Buying Tips:
What about memory cards?
There is no universal memory card to fit all digital cameras – not yet, anyway. Based on internal politics, design considerations and financial reasons, individual camera manufacturers typically adopt a particular style of Flash Memory card for their cameras. Some manufacturers will even split their alliances – one type of memory card for professional-level cameras, and another type of memory card for consumer level cameras. When buying a new Flash Memory card, remember which camera you have and the type of card it requires. Some camera snobs (like your humble writer) will even selectively buy a digital camera based on the type of Flash Memory card they prefer to use!
The most common types of Flash Memory cards are:
Compact Flash, or CF – Roughly the size of a silver dollar (though not round), the CF card is one of the earliest types of Flash Memory cards and is most often used in professional or semi-pro digital cameras.
Secure Digital, or SD – Roughly the size of a postage stamp, the SD Card is available in a wide range of storage capacities. It’s inexpensive, durable and amazingly lightweight.
Memory Stick or Memory Stick Pro – About the size of a small stick of gum, the Memory Stick is meant for Sony Digital cameras.
XD-Picture, or XD Card – Typically found in Fuji and Olympus cameras, the XD Card is about 40% smaller than the SD card.
What’s the difference between optical and digital zoom?
Like megapixels, manufacturers frequently throw around big numbers relating to digital zoom. Like megapixels, you should ignore them. Optical zoom uses real optics to get you closer to your subject, while digital zoom merely takes the same amount of pixels you would have in a standard shot and blows them up to fill the frame. The camera captures no more detail. It’s the same zooming or cropping trick you could pull in Photoshop, done in the camera on the fly. While that can sometimes be handy, image quality suffers severely as a result, and most photographers would never use digital zoom.
What Should I look for in an LCD Display?
Camera manufacturers market display size quite prominently because it’s easy to visualize, but other factors also come into play. Resolution (usually measured in the number of pixels, like 461K) will determine how clear the display looks, and brightness will help determine whether it gets washed out when shooting outdoors. An optical viewfinder makes a great backup when shooting with a less-than-ideal LCD.
LCD screens are measured diagonally and 2.5 inches is a common size. We prefer even larger ones, up to 3 inches. If your eyesight is a bit challenged, definitely look for a larger LCD. Screens are measured in pixels, just like image size. Again, the more pixels, the better the image you’ll see on screen.
What about shooting video?
Within the past few years, video has gone from a novel sideshow that yielded almost unusably bad results, to a legitimate secondary purpose for many point-and-shoot cameras. Although you probablt won’t want to replace your dedicated camcorder with a camera that also shoots video, many will do the job just fine for short, impromptu clips.
First off, pay attention to the resolution a camera can capture – VGA (640 x 480) is now common on point-and-shoot cams, while 720p is getting more frequent and 1080p sometimes crops up on DSLRs. Video in the AVCHD format – the same type real digital camcorders shoot – is preferable to other formats. Pay attention to the encoding bitrate, measured in megabits per second (mbps). The higher the rate, the more detailed the videos will look, although they will take up more space on your storage card as well.
