establishing hyperfocal distance?

Hi Everyone,

I have been doing some tests to understand the  hyperfocal distance, but its not looking sharp;so i dont think i am getting it..

here you can see 2 images(first is taken with manual focus and the second with live view ,manul focus dof button)they are quite identical and the left part is quite out of focus compare to the right, why do you think is that, can you tell me what is my mistakes,please?

i was focusing around the first tree, as the hyperfocal distance was 2,5 meters.(f16)
