A scene lit only with flash exposes the sensor for about 1/1000s, regardless of shutter speed selection. The camera can be shaking violently afterwards, but that won't be recorded.
A photo of a golf ball leaving the club or whatever, they can leave the shutter open for ten seconds, it's all about the strobe's duration.
Your point is that I did not record 1/50s of actual exposure? You do have a point. Potential shutter shock is a new thing for me, I'm still wrapping my head around it.
Believe it or not, for the last two weeks we have had absolutely no sunlit days. It's always been cloudy and gloomy. In november in my region, that means low shutter speeds outside, so I've relied on the flash to get more light. A mistake if I understand you correctly.
I could duplicate the test by using all the lamps I've got at home (all the incandescent ones, at least, with broad emission spectra) to try and raise the esposure to around 1/50 without flash.
In any case, looking at the results above, the flash pictures appear to be the worst ones.
