The IQ out of the Merrill sensor can beat any full-frame camera up to (and including) the original A7R, imo. The files are extremely printable. Jpegs are a bad idea.
It's a specialty camera: so yeah quirky and difficult until you learn it. Treat it like a technical camera and you'll be blown away, at least that's what reviews say (I treat it as I would any other camera, though the technical limitations fit my style of shooting). And nothing else has the Foveon Merrill look. It's already a classic.
Some questions: why shoot auto-iso Jpeg? Why is 3:2 refreshing? If you want to shoot mono, you really should be developing in SPP, as there are some blue-channel tricks that will allow you to shoot around 1600 iso and get pretty clean, filmic files.
I hope this thread turns into your one-camera 2016 thread, as that really interests me.
