The reason behind 52 rolls is to enhance your skills, maybe try new film and different ways to process it to push the boundaries. It certainly taken me on new road!
Agfa vista 400 pushed to 800; for a consumer film, hats off, not much colour shift, none too dark shadows, all in all a great little tool to have in you arsenal. To be honest, if comparing whilst pushed, im almost slightly preferring it to portra 400.
Give it a go!
