I recently acquired a Vistaquest 3Mpx mini-camera. Vistaquest is a small company specialized in making very small cameras with not much quality; made of plastic and without LCD screen, the pictures taken are very saturated and very contrasty. I bought the VQ-3005 model to play and see what can you get with one of them; it has a F2.8 lens, it cost me 40 euros (50 dollars) and its size is similar to that of a lighter.
These are some of the photos that I’ve been able to get; to center the camera correctly is quite complicated because of the lack of screen, but maybe thanks to that some of the pictures are more interesting. The only pictures that I’ve retouched are the ones in black and white, the rest I’ve uploaded them as the camera took them.
If you are interested, you can browse around this search in Flickr where you can see really impressive photos taken with Vistaquest cameras.
