Title: Soft wide open, bad flare
Review: I compared this lens to a Sigma 30mm F1.4, the Canon 24mm was softer at the same f2.8 stop on both lenses. Neither lens is a great lens with the sun in frame, which I expected with the Sigma, since it is designed for speed. The Canon 24mm is not that fast of a lens at f2.8, so I thought I would use it as a sunset lens. The lens makes a horrible triangle shaped flare, along with other rainbow patterns. The lens also did poorly with shooting a skyline at night. I was disappointed, maybe stopped down it would look better, but that point your at f4, 5.6, 8, and there are plenty of lenses stopped down that look great. Also manually setting at infinity, wide opened, seemed slightly off the mark, I only shoot manual, since I am a professional and use a loupe to always check focus, but I was also hoping to have a lens I could pull out in a dark moonlit landscape and know for sure where infinity is. Might as well shoot though a lens cap.
