Lens Distortion for 18-105 Nikkor increases in ACR 6.4 beta

Question

The lens distortion correction on an AFS DX Nikkor 18-105mm seems to INCREASE Barreling instead of decreasing it. To get rid of the barreling I have to cut back on the Distortion correction. Anybody else experiencing this?

Answer 1

What you say about overall usability is true (and unfortunate; all my film camera lenses, no matter how humble, had full control of all pertinent information), but I was referring to the corrections only.
So far as software is concerned, it won't perfectly make a silk purse ... but it comes damn close! Years ago, I did lens testing, for oscilloscope cameras, and the rigor even for that was very demanding. What I know about the conditions necessary for obtaining repeatable results during such testing cannot change unless you are willing to accept less than optimum results. The penchant to "Let software correct it" has some painful connotations!
Of course, the major source should be the lens makers themselves, but I fear this is a pretty guarded secret. No one wants to admit their failings, and because of the software correction capability, I suspect that certain parameters are of less concern at the lens tradeoff level. But Nikon or Canon isn't likely to tell you that!
