ADC works when shooting in .jpg but not RAW so I'm not sure what the setting looks like on my camera since I shoot the latter. That being said, though, and from what I've read, the function does work rather well in correcting both pincushion and barrel distortion to some degree.Do you keep it on or off?
I see that it was off by default but I turned it on. Didn't see much difference but I didn't really shoot graphs and charts
