Nikon "auto distortion control": how well does it deal with barrel distortion?
#4
Here are some sample pictures:



D5000



AF-S 35/1.8

off

on

AF-S 18-55VR

off

on

I guess the effect is clearly visible.

I don't have any samples of the 55-200VR at the long end, but it works there as well.



Auto-distortion-control is disabled with the AF-S 85/3.5VR even when set to on, but this lens doesn't need it.



Auto-distortion-control has its pros and cons.

It slows down in-camera picture processing, the photo is displayed with a delay.

When taking pictures of nature mostly you do not need it.

For a sunset over the sea it is very useful.

For architecture it helps a lot.

I would probably leave it off when taking a picture of a group of people at 18mm, because the "straightened" faces at the edges do not look natural.

And for sure it only shows effect on the camera created JPGs, not in the RAW files.

But for most purposes the D5000 produces good JPGs when you tweak the picture controls right.



Edit:

I just checked, it does show an effect on the RAW files as well...

Could that be?



Edit 2:

Yes it can be. When auto-distortion control is set to on, View NX 2 will show the NEF files corrected as well.

RawTherapee however is not able to interpret that.
