@zerone I did a little research and found two online DOF calculators giving hyperfocal distances of 19m and 19.96m for 55mm at f/8. I also found there is a hyperfocal distance given in pyexiftool from your raw file. That one reads 26.8m.
Your focus distance is 3.35m, so it’s not surprising that the branch at the top left is the clearest. That’s the closest to the 3~4m DOF listed. Before you spend money on new lenses, learn how to get the most from what you have now.
