The APX 400 Professional Black and White Negative Film from AgfaPhoto is a high-speed black and white film for conventional black and white printing. The film's nominal sensitivity is ISO 400/27°, but it can be effectively pushed to ISO 1600/33° for use in low-light situations and with fast-moving subjects. As a result, the APX 400's applications are nearly limitless: action, sports reporting, fashion, and advertisement.

In black and white chemistry, standard development produces a fine grain texture with high resolution and tonal latitude. The film also responds to push and pull development; however, prior to shooting, testing is recommended.

This item is a 36-exposure roll of 35mm (135) film.
