strange behavior of my 20mm on 1.7.

Hello, I noticed about a half stop darker exposure on 1.7 compared to other diafragma's of my panasonic 20mm wonder what caused this differences. Any thoughts ?

See samples. No PP and all parameters the same except change of diafragma. 1.7 and f4.0

Thanks peter

F  1.7

F4.0
