My 50mm/f4 Zeiss Distagon lens is one of my favourites, and it continues to surprise me. I wasn’t quite pointing at the sun in the image from the Scarborough Bluff’s on New Year’s Day, but it was certainly in the sun’s direction. Flare is not an issue at all. (Of course having a lens hood on the lens helps).
