It is turning cold and wet in Hong Kong. I usually bring along the GX200 mounted with the wide converter in such a weather as the raindrops will less likely get into the lens barrel while I shoot in the street. If you wonder, the blurry background is not a result of extravagant cook-up from post-processing even though the primary subject has been sharpened and warmed up a bit. The technique to bring about a blurry background and a comparatively sharper primary subject in the final image is actually an old trick, which resembles achieving the swirling visual effect by way of slightly zooming the lens while pressing the shutter release. But instead of zooming the lens which is impossible on a camera like the GX200, one just needs to set the shutter speed barely lower than the safe value (and turn off the anti-shake), and push forward the camera gently while snapping the shot. Then, just try and err to find the best result you wish. Mind that this trick best suits a static primary subject, especially if it is less well-lit than a brighter background.
