Case where MF has advantages over AF are :
- shooting in dark conditions where AF can't work
- shooting a very fast event which you are expecting and which you can pre-focus, and wait for the exact moment of the event. AF would ruin the timing
- shooting an image where the point of focus is outside the cluster of AF sensors (using AF to focus and then recompose is not accurate. The more you move the camera when recomposing, the worse this inaccuracy gets)
- tilt/shift work. There are no AF lenses which do this, afaik.

I do have DA200mm & A*300mmF4
If you feel like using MF on DA200mm it is quite ok as its focus speed with SDM is superfast.
I am used to shoot bird in flight image with the MF A*300mm F4
B I F shots in city Sept 6 (Page 1) - Gallery - Manual Focus Forum
That has shown that MF guys are no slouch too
