That is what I suspected. You can still stop down your aperture to increase your DoF, and if your camera cannot increase flash output, you can increase your ISO to compensate for exposure.
At this point, do not be concerned with added noise due to increased ISO. Just work on proper exposure with best attainable DoF. Eventually, mounting a speedlight to camera hotshoe will allow more illumination, so you can drop ISO and still use f/16.
Lets be more technically astute.
1) Do not use f/16 if at all possible. F/8 is sharpest, and f/16 is diffraction limited.
2) Do not go higher than ISO 400, and if at all possible drop to ISO 200.
It has all of 7 stops of useful dynamic range at ISO 200, only 6.2 stops at ISO 400, and 5.2 stops along with horrid noise at ISO 800.
