Have a number of images with 5D and 24-105 at wide end - knew distortion would be noticeable and it is

I may not be using search correctly, but couldn't find any relevant posts

DxO supports a whole lot of lenses, including long focal length - curious what they do with these lenses

My experience (with Nikon cameras):

The distortion/CA correction works great, as do the lighting and film looks where appropriate. I'm not impressed with the lens softness/sharpening and never use it. Check out the 1:1 appearance with your camera, it's not always the best demosaicer for detail. Note that the DNG output is in linear form, with a much larger file size than the original raw in mosaic form.

DXO seems to rely on maker note information for obtaining lens information, so if you've already run the file through a third-party tool (such as ACR), you probably won't have access to the distortion correction.

In all, kind of a mixed bag for me: great/easy distortion correction, but not the best raw converter. I use it mostly as a pre-processor (distortion only) to panoramic stitching.

You might also want to look into alternative (to DxO) solutions provided by Kekus (Mac) or PTLens (PC). I've not used that last versions of DxO but I seem to remember that distance info was not provided on Canon lenses to DxO and had to be entered manually. This might be incorrect with the last versions and newer lenses/bodies like your 5D and 24-105 L.

This is still the case. I've got the current version of DxO and with the 5D and 24-105L there is no distance info available.

DXO and the 24-105 is a great combination

I use DXO Pro with my Nikon D200 and my favorite lens, the 18-200 VR. DXO does a great job correcting for it's unique distortion. You can go the the Ken Rockwell web site to see how DXO works with Canon lenses. http://www.kenrockwell.com/tech/dxo/optics-pro.htm To get the full benefit of the program, you'll need to shoot in the RAW format. I use some of the features in DXO and then open the picture in Photoshop to put the shine on it. DXO can be used as a stand alone or as a plug in. Be sure and check out the film pack, which is an option. You can choose different film or camera "looks," and sometimes it's bingo and some times no.

Thanks, i downloaded PTLens -- price, and the plug-in works with my work-flow

so far have only used it for lens distortion and perspective almost entirely with the 24-105. perspective sliders aren't quite intuitive, and are "sticky", but i'll blame the later on my old, slow computer

side-by-side screen comparison looks good, but i haven't made any large comparison prints yet

the older comparisons between PTLens and DXO were favorable to PTLens, and the latest reviews for DXO are somewhat mixed, 16-9 in particular

other than the time involved, is there any reason for not processing images for distortion? i'm surprised at the amount of correction at mid and longer focal lengths
