The ordinary pocket kodak takes pictures 2 in. by l 1/2 in., and the folding and newer kodak takes pictures 3 1/4 in. by 2 1/4 in. When closed, the folding kodak measures only 1 5/8 in. in thickness. These cameras, having a fixed focus (that is, allowing of no adjustment of the focus for near objects at different distances), are unsuitable for any but fairly distant views, where the variation in focus is very considerably less than with near objects at varying distances, because everything beyond a certain distance is more or less in focus. This result is obtained with a short focus lens and a small stop, but as the latter means long exposure, and as short ones are essential to good hand camera work, the fixed focus patterns cannot altogether be recommended.
