Ok, that's still pretty good. Cropping does help. The upper right corner is a bit soft, but there's nothing to see at the upper left and the pavement patterns are irregular, so it's hard to see distortion.
Yes, do try one of the DLO programs with that lens. I think you'll be impressed. Of course, DPP has DLO and shipped with your camera. You may need to update to the latest version after installing DPP on your computer.
DPP is very good software, but clunky to use. I use DxO Optics Pro 7.5 because it's intuitive, fast and high performing. (You can test it with a free 30-day trial). Lightroom also has a DLO function.
