Low noise benefit of FF vs APS-C equals ... zero

Yup. APS-C and FF basically = excluding limits of lens. Only problem is will Pentax listen? Will they make a 50-135mm f/2.0 (no need for it though) as a true 70-200mm f/2.8, a 200mm f/2 for a true 300mm f/2.8, or a TS lens? Until they do, I doubt people will take Pentax seriously.

Ohh... I really want a 30mm f/1.4 or f/1.0 (I doubt the f/1.0 :D)

I guess it makes sense for Super long lenses, but what about normal lenses?

If you put that 400mm f/2.8 on a FF body, how would it be possible to get the same bokeh as it on APS-C with the same FL? A 280mm or 300mm f/2 would be the only option and as of now there are no production 300mm f/2s.

Or a normal prime. To get the bokeh of a 50mm f/1.4 on FF, you would need a 35mm f/1.0 on digital sensors. Of course, 50mm f/1.4 bokeh on FF is (IMO) TOO creamy and f/2 would be enough for most people, but that would STILL require a 35mm f/1.4 (canon sells one for $1300)
