I must say the zoom range is useful for street photography, certainly on the crop sensor. It matches the lenses I used to use in the days of 35mm too, so should I ever take a full frame camera round town it should work equally well.
These next two leave me undecided as to whether the colour version or the black and white conversion works better. It was the colours and the lighting that made me put the camera to my eye, but it's the chap's expression (which materialised during the picture taking) that makes the picture.
So far the lens seems to be a handy piece of kit for the money. It'll certainly come in useful as a travelling light lens for fishing.
