Shot only as a jpeg, top image is the uncropped but sized down version. I know it's not perfect, but compromises must be made to capture these fast little birds (at least for me). The light could have been better, I admit. I'm still impressed with the much reviled Sigma 24mm f/1.8, though. This was at f/2, 1/1600 second, ISO 2000, negative 1/3 exposure compensation, no NR in camera, and none in post, and no sharpening...and the aperture is almost wide open...on the puny, incapable 6D!! This particular lens is not really at all "soft", in my opinion (at least not in the middle 30% of the frame at wide aperture). I did tweak color/vibrance slightly and removed CA, and tweaked the fringing sliders slightly. If I had shot it as a RAW, I might have been tempted to tweak more...but this was shot through glass into low sun backlight, so it didn't feel worthy of RAW. It's possible there is some sharpening the camera added in its jpeg processing, because I see a faint outline on the left edge. But it's not all that noticeable. The bokeh highlights, are also not all that objectionable...again in my opinion. I've really not shot this lens often enough at wider aperture, but I want to do it more often now. What's really wild are macro images at this wide angle...
