Light here around is just lousy these november days. But I tried my ZE21 all the way to f22. On the smaller pixels of a 450D I start to see diffraction around f13, f16 is clearly mushy, f22 bad (for what this lens is capable of at f2.8 to f11, again on a 450D).
Most surprising, however, was the deep DOF allready at f5.6.
