Attempting to verify the sharpness of my new (used) Zeiss 24mm prime

I would appreciate it if some of the experts here could analyze these shots, and let me know if necessary if I'm not doing this test correctly. I took these photos on a tripod in A mode, RAW, DRO turned off, and converted to JPEGs using Sony's RAW software. Camera was about 5 ft away from the whiteboard I put the targets on. Please ignore the tally marks. One thing I'd like to point out is the center sharpness seemed to be equal on the Zeiss and my 1650 kit lens (I'm not sure if that's a good or a bad thing?)

Zeiss 24mm @ f1.8

Zeiss 24mm @ f8

Zeiss 24mm @ f14

Comparison of center. I used manual focus with focus peaking; could my focus be off in the second shot?
