I have a new camera, a Pentax KP, and thsi came as a surprise. Shootign against shedding sunlight I got a red flare on the images. https://img.aspr.gr/images/2020/06/09/90df43e99a358bb3677e74c73ee12842.jpg And this image crearly shows that is sunray caused https://img.aspr.gr/images/2020/06/09/aac03517b0120733bdfd66d711119ee6.jpg The same phenomenon appears in the RAW files, it changes intensity when i stopped down, and happened with TWO lenses I tried. (pentax 17-35 and sigma 28-70) So what the reason can be? A camera fault, or a concidence that the lens coatings created it? thank you
