I have a Canon 2000D DSLR with 55-250mm lens and no lens hood. Recently, I took a picture of a tractor that was in nearly the same direction the sun was shining from. However, the sun was sufficiently far away to be not in the picture.
When looking at the image through the viewfinder, I could see reflections of the sun and thought I need to purchase a lens hood. However, the final image was perfectly fine with no reflections of the sun.
Why is this the case? Why did I see reflections of sun through the viewfinder but not in the final image?
Two pictures taken, I don't remember which is the one that had sun reflection in the viewfinder:
