Was going through various shots amd came across this one taken with the 6D and Sigma 24mm f1.4A. I also have the Sigma 20mm version and although I have not done a side by side comparison yet the 24mm has that little bit less distortion and takes a 77mm thread,Both lenses are great in low light as is the 50mm.Picture taken in my local paddock processed in Picasa.
