Well, it might be "MF" in the digital world, but it's most certainly not "MF" in the traditional 56 x whatever form. So, since the sensor isn't really that much bigger, I think f/2 would be more in line with the camera. But, truthfully, the lens already looks humongous.

The Fuji 6x9 cameras had a 105mm f/3.5, and this sensor is almost half the size of a 6x9 frame! The Pentax 6x7, with film 50% larger, has a 105mm f/2.4!

I just don't quite get it, other than the progression of "my sensor is bigger than your sensor" kinda one-upmanship common these days. I mean, if it was a black box and a control system to shoot attached to a technical camera, I get it, but the form-factor is meant to shoot out-and-about. You'll have to push the ISO to 4x to get the same amount of light compared to a f/1.4 lens on FF. And I doubt there will be significant differences in the image compared to a high-resolution DSLR FF camera with a good, fast lens, at 2 stops lower ISO or 4x shutter speed.
