Let's face it, if you're going to buy one of these ultra tiny cameras, you should do it for the novelty factor alone and nothing else. Most offer poor quality construction, plastic lenses and a resolution that is less than exciting unless you're used to VGA-type clarity. Of course, there's the cool factor of a digital camera that you can tie to your keychain, and that's what these are all about...
Micro Digital Camera
The Micro Digital Camera is a 4 in 1 digital camera. You can take pictures, videos, record your voice and even use it as a webcam. It can take up to 20 hi-res pictures at 1280 x 960 pixels, or 243 at low resolution. It's so small, the product sticker is nearly bigger than the camera itself!
2.0 Mega Micro Camera
With this micro camera you can store your blurry and pixelated memories inside the supported 32GB memory card. The 2.0 Mega Micro Camera looks like a tiny DSRL and has a 2 megapixel resolution for pictures and 640 x 480 pixel video resolution. Transfer your files using a USB cable to your compute, but hurry up, the battery is only good for 2 hours.
Minox Micro Retro Digital Camera
This is considered a monster when compared to the other two, but the looks alone will make up for the extra heft. Modeled after the Leica M3, the Minox manages to push all the right buttons aesthetically. The Minox also takes decent shots, especially when compared to the other two. This isn't a toy...more like an exercise in good/bad design plagiarism.
