Hey Guys, new here, but been shooting my beloved Bessa for years.

Im looking to get into MF. The only camera I've used thus far was a hasselblad. And what a pain that was to load. Which body would you say allows the users to snap in a roll and get shooting the fastest? I'm thinking maybe a Mamiya 7, but, I don't really know, and this is one thing that spec lists don't cover.
