The Alpa is the only mirrorless camera which uses the new Sony 101 medium format sensor. But unlike modern DSLR digital medium format cameras the Alpa is quite tricky to use. Kai surely got though a lot of annoyances to make it work. It would certainly make sense for Sony to launch a RX medium format camera with such sensor. If they manage to price it below $10,000 there may a market for this?
