In the first post you saw the Zenitar picture. Here is a version taken with a longer focal length, my first attempt to make a Shallow DOF Mosaic:

K10D, Sigma 30/1.4 EX at f/2, 35 pictures stitched
The background is now nice and soft, the Sigma = good bokeh.
If this is better or the same or nothing to care about will vary from person to person but also from situation to situation. I have found that the subject need to be large. A car is OK (if you take pictures of cars that is

), this sculpture is a tad small but it works.
There is a white sculpture in the background. It looks like this with this technique:

K10D, Sigma 30/1.4 EX at f/2
The picture of the white sculpture suffers from boring composition. I wanted the "hand" to be there but the overall result is nothing compared to slowly walk around it.
In the next post another picture, the place revisited...
