Provia 400X for example is excellent pushed to 800 and 1600, and even quite good at 3200.
And excellent pulled 1 stop.
It pushes better than the current 400 CN films.
The film is specifcally designed for push processing.
This film belongs to the best color films ever made.
Astia 100F and Provia 100F deliver also excellent results pulled 1 stop and pushed 1 stop.
