The fisheye lens was originally developed to help meteorologists to shoot the whole sky and study cloud formations. I don't know if it's used that way anymore, but I do know that it gives an amazing effect and that the Lomo Fisheye One is a perfect way to rock it sky high!
The Holga 135 BC may be the little sister of the original, legendary Holga, but it ain't less of a camera. It's simple, its light weight, it's small and it got all the great features of its bigger brother - including the fantastic effects of the plastic lens and dark corners (vignette). Plus it use regular 135-film which is cheap, easy to get, to use, and any one hour lab can develop it! But most of all, the Holga 135BC is FUN, FUN, FUN!
