Mirrorless interchangeable lens camera systems such as Micro Four Thirds, Sony NEX, and Samsung NX were designed to cater to users who find dSLRs too heavy and bulky to operate. Well, these formats now have a new competitor--sort of.
The Chobi Cam One is a miniaturized dSLR that comes with different lens attachments users can deploy for varying picture results. However, don't expect this to dethrone dSLRs or mirrorless system cameras anytime soon. The pictures from the Cam One measure 1,600x1,200 pixels, and it captures video in VGA resolution only.
The mini shooter has a microSHDC slot that supports cards up to 32GB in capacity, and it has a USB port to connect to a PC for image transfer.
If you're looking for a quirky toy camera, the Chobi Cam One is to be considered. It can be had for about $118 from the JTT online store, but shipping is limited to within Japan only.
