>>3273092apx 400 isnt the same anymore, its a really different emulsion. the new emulsion is kind of flatter than most other films, with a bit more shadow details, and pretty controlled grain, even when pushed. its my go-to all round b&w film. pic related is apx shot at box speed.
Rollei RPX 400 is exactly the same emulsion as old apx 400, it feels more classic than the new apx, has a bit more grain, is a bit more contrasty, and pushes really well.
