Best to post a sample image. It could be subject movement, DOF too shallow, miss focus or a number of other things.
50mm f2 ISO500 Flash 1/2
here if you zoom on his face you wil see that is soft focused.
That is the sharpness, I would expect at F2 for that lens. What I see is noise/grain. You need more light to reduce the noise. Get a stronger flash, go FF or lower the ceilings.
I see Thank you.
I would actually expect a bit better sharpness than this. I sold my 50 STM when I got the Sigma 56 F1.4, which gives much better sharpness than this, even at F1.4. But my 50 STM still performed better than this, I think. Have you tried the lens in other conditions?
Thinking about what you said about the conditions, this could be a combination of hand shake and subject movement. If the ceiling is really 30 feet high, I'm pretty sure you're not getting much, if any, benefit from the flash (that's much too high for an effective bounce). What color is the ceiling? If what we're really seeing is the exposure from available light, 1/100 is just not fast enough to freeze even slight subject movements or hand shake. Take a shot with the lens in bright light at a fast shutter speed (at least 1/250) of a flat detailed surface at the same distance as this shot, and check how sharp it is at 100%.
