It look like I does not have enought depth. what > should I do to get total sharpness of the subject ? Olivier, the math is simple. closeup + hand-held = no depth of field. No matter what closeup equipment you use, there's very limited depth of field unless you stop the lens down to a very small aperture. Small aperture = slow shutter speed, which means tripod. In some cases one can arrange the photo elements more-or-less in a plane but that can't always be done. Using a small aperture, you'll need to be more aware of backgrounds and how they will appear at the smal aperture. Use the camera's depth-of-field preview to see if the background areas become unacceptably busy or cluttered at the small aperture.
