The technical specifications say that it has an equivalent of 24mm. lens – it does not mention anywhere "the eye of the fish", and as the fish-eye lenses are usually ultra-wide (about 16 mm), this also seems to indicate a straight lens.
This random test sequence seems to indicate that it does not have a fisheye lens either.
You may need to consider the distortions of light. However, you will have to do it with all lenses that are not industrial grade aerial lenses.
