Ahsanford here is a picture of the sky at 1.4 and a blurred one of my pond at 1.4 taken at the same time of day. I notice the sky but don’t notice the corners darkening in the pond. That is what I meant.
Dear LSXPhotog, did you get the Sigma 24 Art? What's your feedback on that lens? I'm seriously thinking on getting one, as I have had two copies of the 24L Mark II and had to return them as they missed focus a lot when shooting wider than f/2.2 on my 5D3's and 5D4's.
