Abstract: IT IS not my intention to present a technical nor mathematical discussion of this subject but rather to present a somewhat simple and practical method by which comparatively short focal length motion picture projection lenses may be compared. For example, a motion picture theatre owner, manager or projectionist hears about some new projection lens which he may buy at a certain cost and then just as he is about to purchase it, another lens at double the cost say, is shown him. Which shall he buy? How can he determine whether or not the latter lens is worth twice as much as the first? How is one better than the other? In other words, he should have some practical means of determining under his own particular conditions, of screen, length of throw, size of picture, etc., which lens to purchase.
