The L-CW is a version of the Lomo L-CA with a very wide 19mm lens. Some Austrian students discovered the cute quirky L-CA film camera on a visit to Russia in 1991. They loved the pictures from it and with some smart marketing started the Lomography movement devoted to images taken with this camera.
This camera is relatively expensive. It's images are not great, but have their own persona. The Russians were heavily influenced in its design by the earlier Japanese Cosina CX-1 which I also have in my collection (there is a film in there now, so maybe I'll post some pics soon.)
