Cows in Berkeley?
Someone once claimed photodo put a high emphasis on wide open performance.
Judging by how small the telephone poles look, to be able to pick out the
wire on the 500mm image implies the lens is pretty good. It's interesting
that the rope hanging from the trestle is easily visible in the 500mm shot
but can just sort of be seen in the full pixel 150mm image. I would also
agree, the film is limiting the performance.
The trestles(?) look similar to the those supporting a cat walk which runs
between the high voltage lines in the nearby baylands. Is the farmland
former marsh land?
