I bought a Mamiya AFDII with a Sinarback 54m 22mp back as my first MFDB. Then, because the Sinar only shoots tethered, I got a Leaf Aptus II and my freedom. I decided to sell my Sinarback so I got it out cleaned everything up and thought maybe a technical camera would be kind of cool to use with the back because it really takes nice pictures, but I know nothing about what I need in a body or lenses, workflow, how to focus etc. So any little starting hints would be awesome. My wife already thinks I'm crazy so budget items would be best.
