You've got a great camera. My friend has one and he travels with it. Very sharp images. Can't say the same for my Mamiya RZ. Shoot a couple of rolls soup the film and you won't feel like an idiot. You'll congratulate yourself. May you enjoy it for years to come!
I have two RZ's and I have to say my experience is completely different. Awesome picture quality. Use a light meter to set your Aperture and Time.
