Thanks Peter for your notice, but I did not really meant wide aperture,
moreover, I rarely shoot wider then f/4 by 28-70. My thought is backed
up by a sharpness (that I find even excessive in case of some sensitive
portraits) and regular apertures. That boosts the feeling of reality.
I never experienced that feeling looking even at mere of 10x15 prints
shot by other glass I used to own (probably sometimes except of Sigma
70-200/2.8 APO EX, but this is another range).
