So I made some further observations after the first review yesterday. I also got a message telling me that other and more detailed shots are needed to see. So here we go. Below you will find the corner and center crops from shots I took today in the morning. The shots were made handheld and the ISO was limited to 100. First the center shots of a street scene using apertures 2.8, 4 and 8 As you can see, the center gets sharper at f/4 to soften up at f/8. Next you will see the details in the upper right corner. As you can notice there is a slight purple fringing which gets softer when the lens is stepped down. Strangely enough the shot at f/4 is not sharp. I think the branch has moved in the wind, but the wall looks sharper.You can find the full SOOC shots here. As a conclusion I have to say, that for me the lens is very fine wide open. I haven’t considered if I prefer f/8 or f/16 for my night cityscapes. What still is strange to me is that the lens falls in to a resting position when turned off with a hearable soft *tock*. What I have not tested by now is the fact, that the lens seems to take long to “boot” – the Iris is closed and opens wide only to get stepped into positions. I will save this for the next blog entry. If you have questions you can also leave a comment. @Edit20120420: A reader mentioned that he thinks the blurriness at f/4 in the corner could be due to the exhaust of the truck you see. This sounds reasonable as everything is a little bit blurry in that corner.
