There are Three Positions.
AF.S, C and MF. MF ( for Manual Focus ? )
Thanks very much for all the helps.

Because the DFA 100mm f/2.8 WR does not have a focus limiter, it's best to use Manual Focus - even though the lens has quick shift.
Why? If you miss focus, the lens will move through it's entire focus range and the bug/flower/whatever will probably change enough for you to loose your focus.
Your images above have lots wrong with them as far as focus, as well as your flash is too bright and it is destroying/blowing out the details.
Use a decent/appropriate depth of field as a first start, and work your flash exposure via the minus exposure compensation for the flash or the generic exposure compensation for the camera.
Tripod is my recommendation, but if you can work your technical factors for a shutter speed of 1/500 or greater, you should be fine too.
The main thing is to get to know the interaction of camera/flash/depth of field and how your lens works around the factors.
