Your Lens is perfectly OK...

If you use Photoshop, you can use the Lens Correction
Filter to correct the image. The values:

  • Remove Distortion +2.2

  • Rotation 0.65 Degrees

will make the horizon in the first of your posted images
perfectly straight.

On the second image the values are:

  • Remove Distortion +2.0

  • Rotation 0.55 Degrees

The differences in the distortion values can stem from
two sources: it can be due to the different focus value
(distortion may change due to focus distance), and
the horizon on of the sea is actually not completely
level, but has a slight curve to it.

The rotation values are due to your holding the camera
not level.

Greetings,
Robert
