Just another example of the excellent street photography benefit of the Olympus 17mm's Bokeh. This was shot (late evening-darker than it looks) at f1.8 with focus hitting the back of the mans Kimono, but the transition backwards is so coherent, that the focus area looks to be much wider. Even the sign across the road is almost readable and the lady with the umbrella is also quite defined.
There is a pleasant mix of foreground "snap", without the background being too overtly blurred. It's an old fashioned thinking, made to be of practical benefit, not a deliberate, fast drop off Bokeh in the more modern style. The same image taken with the 20mm Panasonic or the 12-40 zoom (even at f2.8) would show a faster drop off to softness which some will preffer, but for street shooting shows focus misses too aggressively. Bokeh has no wrong or right. Like texture, colour and contrast, it has it's different forms to suit a variety of situations and tastes.
