I am suprised you think the pics are especially good. They are low-res and very hazy. Only the one with the sea reflecting the sun has been tweaked, to remove what would have been an even denser haze.
The camera is a Pentax K5. 1/1000 or so. F6.7 or so. ISO280 on the above mentioned pic, 1/2000, F6.7, ISO160 on the VMC on top pic. TAV mode (you set shutter and F, the camera picks the ISO).
