The APX 400 is extremely powerful and reliable even in low light conditions, providing professional black and white images with high resolution and fine grain. The already very high sensitivity can be increased up to ISO 1600/33° by "pushing" it. The possible applications of the APX 400 are thus virtually unlimited: Action, sports reporting, fashion and advertising. The emulsion is not really new, however, as it is formulated according to the Kentmere 400 formula that appeared on the market in 2004 and has been available as APX 400 since 2013.

AgfaPhoto APX films are professional black and white films with high resolution and fine grain. They offer the best conditions for detailed documentaries or stills with a high aesthetic appeal. But also rapid action scenes or atmospheric moments can be reproduced expressively with AgfaPhoto APX. The advantages of these films are convincing: excellent image stability in homogeneous areas, high edge sharpness, no tearing of critical subject zones, flexible in sensitivity and contrast, exemplary in grey balance.

The APX 400 has a sensitivity of ISO 400 / 27° (400ASA, 27DIN). Alternative exposures of the film such as ISO 320/26° and ISO 800/30° are also possible, but the film gives its best results when exposed at the nominal sensitivity of ISO 400.
With alternative, recommended exposures, quality losses in graininess and sharpness must be accepted. Furthermore, in the case of exposures deviating from ISO 400, it is advisable to first carry out test exposures and developments with adjusted times to check whether the desired results are achieved.
Even if the film does not show any visible changes in its latent image behaviour for a few months when stored properly, dry and cooled, we recommend developing it as soon as possible after exposure.
