I just could not help noting the effect for the Sun went away, to me at least, when I tilted my screen. I am not sure that we still know. | |

As such the apparent dislocation of the sun is no more than an optical illusion caused by the lens distortion. | |

| Aug 6, 2017 at 19:17 | comment | added | user107153 | I agree with @SamuelWeir I think, although I originally thought the barrel-distortion reasoning was really good: it's more likely to be perspective distortion due to the sensor plane being angled upwards. Although the image is missing any useful EXIF data and the person didn't tell us what camera it was taken with, many modern cameras, if they know enough about their lens will, when creating JPEGS, correct for the distortions they know about. So if this was taken with such a camera, it seems unlikely you'd get so much lens-related distortion. | |

| Aug 6, 2017 at 19:05 | comment | added | user163104 | @SamuelWeir Thank you, being realistic, if you are not sure, then I am even less sure. The building distortions, those I think I can justify, but the Sun may be a bit more off line than even barrel distortion can explain. I will edit your comment in to my post? I have no experience of zoom lenses. | |
