Hi!
I think this photo shows a pretty good example of sensor flare. Look below the car's bumper, right of center. I blurred out the license plate, otherwise the photo has no postprocessing other than the obligatory resize:
Olympus OM-D E-M5 // Olympus OM 100 2.8 // ISO 400 f8 1/125s
Cheers!

Looks like lens flare to me -- I see multiple lens elements -- from sun reflection off bumper.
Interesting photo for reflections!

Hi!
Here's an enlargement of the flare. No post-processing other than cropping the flare out of the larger picture above, converting from raw to jpeg, and resizing for this web site:
Note the rectangular shape of at least two parts of the flare. The lens aperture is hexagonal, while both the rear baffle of the lens and the sensor are rectangular. What does this mean?
Cheers!
