Working against the bright light seems to be the biggest flaw of the tested lens. The huge front lens catches light at full blast, so it’s easy to catch massive and intensive flares. And you don’t even need the Sun to be in the frame. What’s more, when taking a picture of a scene full of contrast, where one part of frame is much brighter than the other, we may catch a weak ghosting, as we can see in the last picture below.
