I was impressed by the quality of bokeh from the 12-45. The bokeh balls were notably smoother and cleaner in the 12-45. They both looked sharp and if there were differences, they were very slight.Robin Wong went the extra mile and did a comparison between the 12-45 and 12-40. Interesting.
I would agree that bokeh quality had the largest impact on IQ in this comparison as the sharpness difference was negligible at best. Olympus has placed more emphasis on the bokeh quality over the past 3 years (since the 12-100) and that shows again with the 12-45.I was impressed by the quality of bokeh from the 12-45.

While it's not really possible to compare the old versus the new charts, it is interesting that the new lens starts at it's sharpest wide open while the 12-40 f/2.8 is better at one stop down. Or actually two stops at 40mm.Well here is a link to the brandnew ePHOTOzine review of the 12-45mm f/4, with, to compare, their review of the 12-40mm f/2.8
Do share samples if you have any, because all the samples we've seen so far have been from members of the press, or Olympus Ambassadors, and I'd love to see if the lenses attainable by us mere mortals could measure up to those results.Well my lovely 12-45mm turned up this morning. Seems to sit nicely on the em 5.3. I'm limited to house and garden because I'm in the at risk category, in the UK. So inventive photagraphy it is.
