BobYIL: To see the prices of the latest 40MP backs hovering around $20K indicating to one fact: None of the MF manufacturers are expecting substantial sales quantities to feel encouraged to reduce the costs.
Wow - an IQ180 is a serious investment. I would have a hard time factoring that into my business model, as a pro, now. I still use an Aptus 22 and, as a backup, an original Kodak ProBack. They still get the job done. But there's no way I would reinvest in MF, now. The returns are too-small, mid-market. If I need more MP, I rent a back. The Leafs are great because of the openness of the system. I can sling any Leaf unit onto my beloved ELDs, and I'm off. I cannot abide 645 bodies, so I stick with the V system Hassies.
