Hi, I have been using dslr's for years but have wanted to expand into medium format digital. My interests are landscape, macro, and still life and I have decided I wanted a camera with technical movements. My thought was to spend the majority of my money on a camera and a minority on a used back. I could upgrade the back as my finances allowed. I have read the review's on LuLa but am still unsure which system would be best. My funds are not unlimited and therefore I need the most bang (IQ) for the buck. Any thoughts would be appreciated.
