The chart above suggests a plan for buying the lenses that will be most useful for your own photographic purposes. If you are using a view camera other than a 4 x 5, refer to the chart on page 31 to find equivalent lenses for a larger or smaller format.

A good way to find equivalent lenses for your new large-format camera is to take your favorite 35mm lenses and multiply their focal lengths by 3 for 4 x 5 and by 6 for 8 x 10. When moving up from medium format, multiply your favorite focal lengths by 2 for 4 x 5 and 4 for 8 x 10.

The Soft-Focus Lens. The primary application of the soft-focus lens is in fashion and portrait photography. The soft-focus effect is controlled by inserting disks with cut-out holes into the diaphragm area of the lens. The effect can range from a sharp image, like a regular lens, to a very diffused image that minimizes or eliminates skin blemishes and reduces the amount of retouching that might otherwise be needed.
