Top work, some really nice shots there. Love the last one in particular.
Seems to blur the background quite well in macro mode as well, surprising for a non-SLR camera.
I might be wrong but it depends what the aperture will go up to at what focal length. According to the specs the Aperture is from f/2.8-f/11
When the aperture is bigger i.e f/2.8 you get most blurring and a smaller focal point.
Excellent photos. I like the last one as well
