A wide-angle lens is a must for shots like this, where it is impossible to move back.
MANY amateur movie makers in the novice stage buy a camera equipped with a lens turret, but instead of buying a full set of lenses, at first buy only the standard 1" 16mm lens (or yi" 8mm), intending to procure additional lenses when they have gained more experience. When the time comes for the first addition, the problem is whether it shall be a telephoto or a wide-angle lens. There are advantages to both types of lenses, but apart from the fact that the wideangle lens is usually a trifle cheaper than a telephoto lens of the same speed and qualitv, this lens is generally considered to be the most versatile of any for the following reasons.
For interior shots the wide-angle lens will take in considerably more area than other lenses. With a stand

ard lens it requires a fair-sized room in which to take anything but medium close-ups and close-ups, and a telephoto lens is out of the question for anything but close-ups. With a wideangle lens, shots can be taken to include a person's full length in an average sized room with something to spare, and, of course, can also take the medium close-ups and close-ups to which the other lenses are limited.
When a wide-angle lens is set at infinity, objects as close as five or six feet away, depending on / stop used, will be in focus, and focussing is only necessary for objects closer than this. Therefore, if the lens is left set at ' infinity it will take care of most of those shots which have to be taken in a hurry without time to do very much in the way of lens adjustments. With a standard lens it is nessary to adjust the focus for all distances less than about fifteen feet.
Somewhat akin to the previous paragraph we have the case of the movie maker who wishes to ha\re a fixed focus lens in his turret. The logical lens for him to have of the fixed focus type, is the wide-angle lens, due to its great depth of field. Where extreme close-ups are required and auxiliary lens can be used with a fixed focus lens to bring the focus up short. Another way, if there is sufficient light, is to stop the lens down to say, //ll, which would give sharp focus at four feet or even less. There is also the method, which is frequently used, of turning the lens out of its mount so as to bring it farther forward from the camera, but this method requires either a
