Not quite sure if it's my computer, or your setup, but all of your images in this thread appear to be very soft, almost out of focus. On checking the exif data, speed and aperture look to be about right. Did you have image stabiliser switched on?
Would someone else confirm my finding and if it's just me, then I apologise and hope you don't mind me mentioning it?
I think that Zdenko's images look sufficiently sharp for the size at which they are posted (at least those a couple pages back, haven't looked at all of them).
