I couldn't find anything that would explain plainly what this is, and do I need it. I have Nikon D5300, Firmware version C - 1.00, L - 2.009, and it is with the kit lens 18-55mm VR II.
First, what is Auto Distortion Control, and should I turn it ON on my camera?
EDIT: Ok, I have made some pictures, with setting the Auto Distortion Control on the camera ON and OFF, here is the album. PLEASE NOTE, the pictures without a text in them I forgot what was the option, but you can see there isn't a difference. If there is something that I should be aware of that I can't notice, please tell me. ALSO NOTE that I have been changing the IN-CAMERA option Auto Distortion Control ON and OFF
