The new Lomo LC-A section, includes comments on the camera's batteries (important), specs and some pictures of mine.
One of the Spider's favorite cameras, the Lomo LC-A. Its an old plastic Russian film camera. People call it a rangefinder, but it doesn't have a rangefinder "finder", so it is really a point'n'shoot. In any case, it is still wonderful (and cheap).
The LC-A produces unique images and the camera itself encourages quick, informal shooting. I expect no more than one good shot per roll -- but I am generally surprised at how interesting that one shot is.
I think everyone should try the Lomo out at one time or another.

Foveon is a company that produces the foveon digital camera sensor. This sensor works a little differently than typical sensors. It is used in Sigma cameras, including the DP1 and DP2 series.
In normal sensors, red, green and blue colors are captured by adjacent but separate sensor that together form a single image pixel. In this arrangement, a block of 4 sensors are grouped together - typically 2 green, 1 red and 1 blue. The 4 sensor outputs are summed together into a dithered single pixel. Green must be adjusted because it is twice as luminous as it should be.
The Foveon sensor on the other hand has 3 stacked sensors and the material of the sensor itself filter light into its separate colors. In this sensor each pixel location captures all light frequencies and are summed together to form the final color output.
Common sense would seem to tell us that capturing a single pixel of information at a single point would produce sharper detail that blending adjacent pixels into a dithered mess. And it does, but there is a catch. Although the DP2 is advertised as a 14MP camera, they could each color sensor so its actually 14/4 or about 4.7 MP. Let's just call it 5MP. Most people will agree that the Sigma's 5MP output captures about as much detail as a typical 12MP camera.
But its an apples to oranges comparison, and Sigma DP1/2 supporters will rave about the sensors superior colors and dynamic range. Without getting nit-picky, most reviewers do see the appeal.
At any rate, the Foveon sensor is a fascinating technology. It may or may not be for you, but real choice is always welcome.

I added a number of new pages in the Sigma section. Sigma has had its ups and downs, but overall they offer some exceptional deals. Searching the used market can turn up some super bargains. Higher-end Sigma equipment is excellent, sometimes rivaling 1st parts stuff and often giving us options out chosen manufacturers don't offer at all.
Take a look at what's new under the Sigma link in the upper right menu.
