... Per and Martin, can you perhaps expand on what you don't like about the lens?...
Well, at this early stage my impressions are mainly from the build and feel of the lens, less about performance. It is VERY "plastic-y"; turning the zoom ring feels more like opening a screw cap bottle than adjusting fine optics. To be fair, however, it has a nicely finished metal bayonet, and the sideways play when fully extended is less than many "consumer" zooms from Canon or Nikon. The focus ring is quite smooth, but then it is of the "fly-by-wire" type, so it doesn´t mechanically move anything.
Also, it is quite slow, of course. I really look forward both to those adapters, and to the 20 mm pancake...
Some test shots I did yesterday afternoon of the Stockholm skyline looked a bit soft at the corners, even stopped down (center was OK), but they were hastily made free hand, so not really conclusive. To complicate the analysis even further, I didn´t use my final copy of the camera and lens then, but the shop´s demo, kindly loaned to me for one day while they sent for a blue one for me (that´s service, indeed!). Got the final one in an unopened box today, battery still charging. Let´s see how that lens performs a s a p!
And, it has to be said, the images shown here and in the UKPSG diary are very good; Carl´s gorge shots are downright stunning!
