Right. Not ideal to be honest :D The problem was, there was a lot of shadow and the sun was behind clouds so the light was constantly changing.

Ideal would be:

Iso: 400
F: 5-8
Exposure: As high as possible (Until it matches with the 2 settings above)

For this kind of shot a bit more depth of field would have been better so 2.8 is quite a bad choice :D
