The old thread is so full of hasty comments and off-topic hijacks that it's well worth to begin a new one IMHO.
I like this kind of enterprises and I consider myself a potential buyer. There are three sides that I consider great in the "REFLEX" project: 1) the interchangeable lens mount 2) the fact that one of the mounts will be a standard 42mm thread and 3) the removable film holder. But the positive points, unfortunately, stop here. (And these characteristics are very, very expensive to deploy all together in a camera, but let's skip this point).
The preject is indeed flawed from the roots for one reason, in my opinion: it was announced as a fully mechanical camera, but very soon it was turned into an electronic delirium, from the shutter to an interface to connect it to a phone in order to store the camera settings. There is nothing, absolutely nothing in this world that would open my wallet for a camera produced in small numbers and with no aftersale support and full of all that electronic stuff that could fry for a summer breeze. A bridge TTL coupled lightmeter is all I can tolerate in a camera.
And then there are lots of other details: from the irrational position of the shutter release, to the fact that it pretends to recall the glorious cameras of the '70s (the pentaprism is quite brilliant!) but then it has that horrible right hand "grip" typical of battery-operated plasticameras, the multifunction joystick-like buttons, as well as that fat and rounded suppository-like shape, and so on. You might call these latter details, or matters of taste, and with good reasons, but those are exactly the sides that keep potential buyers offshore. In a word, I don't understand to which market this project-camera is oriented.
