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

I think this discussion is stupid.

For instance I have this lens, a 31mm f/1.8. It is a full-frame lens that's a wide angle. It also has a short DOF.

Is there an equivalent APS-C lens that will give me equivalent FOV (21mm) and DOF (f/1.2)? There is not.

Is there an equivalent APS-C lens that will give me equivalent FOV and light-gathering capability (21mm f/1.8)? There is not.

I don't really care about low noise. I'll get a Pentax FF camera when/if it comes out only so I can have my 31mm become a wide angle.

Low noise is not relevant AT ALL. If it matches the K20D that's enough for me.

NOBODY with a FF cam will stop it down to shorten the DOF of their 31mm f/1.8 camera. That makes the discussion EVEN MORE stupid.

Here's a few pics that didn't turn out too bad. Shot raw, fixed exposures (all underexposed by 1 to 2 stops), incresead contrast, fixed vignetting (amount 20, midpoint 20 in LR), white balance tweaked... Lens is Rokinon 500mm f/6.3. Colors are always a bit weird with this lens. I wish I had a standard color char to calibrate it. And the sensor has some dirt.
