This is a very expensive lens, or it used to be when it was still made. I got the last one I think, of the DK stock. It was the last holdout of the last batch imported and I think it has been sold a few times and sent back. I would have sent it back also, had I paid the full price, about £900, but I found it at £250 so that was a nobrainer. It suffers from zoom crawl pointing it upwards it cannot hold the zoomed out position and it is, I think a bit softer at the wide end at a couple meters than it should be. But the overall quality of the image this lens produces is very likable. It renders a warm tone, good contrast, creamy bokeh and it looks good so what is there to complain about. A little AF adjustment on my K5 and I am very happy.
