Recently I've been thinking about buying a calumet C2 6x7 roll film back for my 4x5".

And to make my decision, I'd like those of you who shoot 120 film with large format equipement to share their reasons here.

Of course I have my reasons, but I'm always curious to read other's reasons and choices, as I always learn tons of details I would never think of.

thanks !


PS : if ever you have reasons NOT to shoot 120 with your 4x5", I'm also interrested
