I'm pleasantly surprised by the quality of this lens and its close focussing ability.
I expect a little colour fringing at the ends of the zoom, most zoom lenses are good in the middle of their range but it's at the extremes; the wide and narrow ends you see how good they really are.
Nothing scientific about these shots, balanced on a coffee cup in the office in normal (i.e. dim) fluorescent light. 2Sec timer, "P" mode and auto WB, no enhancement, shot as JPG just resized in Lightroom and the automatic conversion from Adobe RGB to sRGB on saving.
Can you tell at 14mm which is the Olympus 14-42 and which the Panasonic 14-140 ?
Yes, the 42mm is the other end of the zoom on the 14-42.
