Don't Stop Down "Too Much" (the Lens) When Using the Q!

I am almost sure that the sample photos should originally be sharper, but unfortunately the tester used the Av mode and deliberately stopped down to f/8 something and thus the final pictures are now looking rather soft and blurry! Well, I suppose the tester just used to use his camera as he was using an APS-C or m4/3 camera (for most of the time probably), but however that time he wasn't! :-ohttp
