Just using the one click "process now" feature, I ws able to fix an entire folder of photos that I took of a recent listing. I was a bit skeptical, but when I viewed the full sized before and after images side by side, I saw a major difference. Not only does it automatically fix the barrel distortion based on my lens, focal length and camera body, it corrected noise, lens distortion, some lighting and more! I think that it is definitely worth taking a look at!

That's a Private label of the Tokina 12-24. Identical lens, just a couple hundred bucks cheaper than the Tokina. www.promaster.com I use the ProMaster 12-24.

At almost $1800 it's a stretch, but boy do I love this lens! Only when I have a vertical line in the extreme foreground do I get distortion, and even then it's barely detectable. That said, if I remember correctly the beta Lightroom also had a lens correction slider, didn't it? Does anyone have the current version and can check that?

One other neat software is <a href="http://www.dxo.com/photo" rel="nofollow">DxO</a>, which have the correction transformation built-in for many lenses, at various focal lengths, and with batch possibilities. My sigma 10-20 as a lot of distortion for a SLR lens (like 3-4% in moustache), but since it's really wide, I can enter further in the room and keep the door frame and its verticals out of the frame or crop it.
