As suggested by Jon_T in this post , I have started a new thread for this.
There seems to be an issue about how DXO Optics Pro (DOP) versions 10 and 11 crop raw images and correct lens distortion for some cameras. In that post Jon mentioned that with FZ1K images DOP 11 is cropping more off of wide angle images than the SOOC JPEG and more than ACR/PSE14 used on raw files.
I have done some tests and it seems that with the FZ200 both DOP 11 and DOP 10, when using the DXO Standard preset, crop less rather than more off of raw images at all focal lengths compared to the SOOC JPEG. (My past experience is that ACR produces exactly the same geometry and cropping as the SOOC JPEG, but I have not tested that in this case, but I can do if anyone cares.)
What is more, it seems that the JPEG images produced from FZ200 raw files using the DXO Standard preset in both DOP 11 and DOP 10 exhibit barrel distortion at all focal lengths, decreasing but not disappearing as focal length increases.
I captured raw+JPEG pairs using my Chinese FZ200 at 1X, 2X, 4X, 12X and 24X zoom, and did the same with my Japanese FZ200. With my TZ60 I used 1X, 2X, 5X, 15X and 30X zoom. With my G5 I used 14mm, 25mm and 42mm with the 14-42 kit lens and 90mm and 175mm with the 45-175 lens.
I produced JPEGs from all of the raw files using the DXO Standard preset in DOP10. I produced JPEGs from the Chinese FZ200 raw files using the DXO Standard preset in DOP 11. There are 1300 pixel high versions of all of these JPEGs in this album at Flickr.
Here is a 2X zoom Chinese FZ200 example which compares the SOOC JPEG with the JPEG produced by DOP10.

I believe that the SOOC JPEG is much closer to the actual geometry of the bookshelves.
DOP10 and DOP 11 produced JPEGs from the Chinese FZ200 that were geometrically identical as far as I can see.
DOP 10 produced JPEGs from the Chinese and Japanese FZ200's that were geometrically identical as far as I can see.
At full wide angle the SOOC TZ60 JPEG shows more at the edges than the DOP10 version, but the SOOC JPEG shows barrel distortion which the DOP10 version does not (or does not as much). As the focal length increases the SOOC JPEG and DOP10 version become increasingly similar geometrically.
The situation with the G5 is similar to that with the TZ60.
Other people's experience/evidence with these and other cameras may be very helpful in helping us come to an understanding of the nature and extent of this issue.

. Lots of books! When I finish this I'm going back and look some more to make sure I'm not confused? Can you provide a link to the RAW image like they did in the other thread so that I could try it in my copy of DxO? I'm not as computer proficient as I would like to be, but I was able to get that one, so I would try it again. That was my first time, and I was surprised it worked
