Thank you very much for your advice. The photo had been taken 1/125 sec, f2.5, ISO 200. I guess f2.5 was unnecessarily wide. But, what part of the photo is not sharp? I suppose the far end is appreciably less sharp. As you can see, the ISO has to be pumped up quite a bit, to get the benefit of that sharpness. I bear what you said in mind. I was in shoot-first-talk-later mood. Thank you; much appreciated.

Needs a few degrees of counter clockwise rotation and maybe higher F stop to enhance depth of field.

Thank you. It seems horrible to be fed to an open mouth. So blatant or may be, efficient.
