I was interested in seeing the differences that two different lenses could produce; one is a cheap 35mm Fotasy lens and the other a legacy Olympus 50mm. Both were mounted to my Sony a6000 with a simple adapter. Both are manual lenses.

The Fotasy, a $30 lens bought in 2016, makes very soft edges wide open at f/1.4, and can create some interesting shots.

The much higher quality legacy Olympus from the 1980s makes a pretty nice looking bokeh on f/1.8.
