In DPP on the edit image window, there is a spot/click/button that says Lens Data : no ---- what is this for? I click it and up pops a window with a list of apparently all the canon lenses.
If there is correction data available for these, is there correction data for Sigma, or Tamron lenses? If so, where do I get that?
So far, I don't think I have really needed it, but every time I see it... wonder if I am missing something...
Thanks...

Lens data only for select Canon lenses and cameras. You select the lenses by check mark and then download the data from the Canon site.

It's a bit confusing. First, you have to be editing an image to download lens data. The only data that can be downloaded is EF, EF-S and EF-M lenses. Canon does not develop lens profile data for non Canon lenses.

Say you're just starting to use DPP. If you go and select more than 30 profiles (as I remember), the software will let you select all those lenses, but will then throw an error about not being able to download that count. Also, the files are relatively large and depending on your connection and equipment, the download and install can take several minutes (or much more) to process. If you use extenders, note that you can obtain profiles for the lens and separate profiles for the compatible extenders. Use the check boxes to filter / unfilter the list and types of lenses presented within the selection dialog box. Best practice is to select and install just the lenses you own first and add more when your situation changes.

During the edit process of a RAW (CR2) file, select the following boxes: Digital Lens Optimizer, Color Blur, Peripheral Illumination. The final setting - Distortion - can have a profound impact on your image. Depending on the lens, I see most on wide angles, this may produce unexpected and undesirable results. It does have a slider to let you control the effect.

Btw, if you use lens correction in DPP, turn off the in-camera lens correction so you don’t apply the correction twice. Preferable to do it in DPP as doing the correction in-camera negatively affects the burst rate.

Absolutely download the data for your Canon lenses (this feature is for Canon lenses only), and then select Digital lens Optimizer, Color Blur and Distortion in the Image Lens Correction panel for all your raw images taken with your Canon lenses. The feature optimizes sharpening and other characteristics for Canon lenses and does a great job at it. It is not automatic and needs to be applied for each image. You are cautioned by Canon to lower any sharpening you've added to prevent halos and other sharpening artifacts. You can reapply extra sharpening if you think you need it. If you use Canon before/after tool viewing tool (which is unfortunately not active while you are still in that panel), you will see significantly sharper and cleaner images as a result and with no artifacts.

That actually is not necessary to avoid double application of the distortion data. It doesn't apply anything twice since the software in the camera and DPP are both proprietary Canon software. DPP understands what has been applied in camera and what has not. If for instance you have a recent Canon that allows you to apply distortion data in camera, as my 7D Mark II does, then in DPP the distortion check box is already checked. The same is true for peripheral illumination and chromatic aberration . I just tested it myself to confirm what I'm suggesting. However, I don't use the distortion feature because once applied in camera the images no longer display the original focus points used. This is all presuming one is shooting raw.

DPP has some bulk / batch editing options. When you initially open DPP and navigate to a folder full of CR2 files, you can use Edit / Select All from the menu. You can then use View / Tool Palette. If you change to the Lens Correction table on the palette, you can update all the images at once. I've read the suggestion to adjust the sharpness setting on this panel to 0, apply the lens corrections, and then update the sharpness setting back to the desired amount. I did this approach for a while, but can't discern any difference and have dropped from my DPP workflow.

Finding a repeatable and reliable bulk-approach to DPP takes some effort and some internet research. From Art Morris I learned to create Recipe files with Noise corrections stored for ever ISO value between 100 and 5000, my own personal limits for my 5DIII. So, I sort my CR2 files in DPP by ISO descending. I then use the Info panel and select the files in groups by their ISO value and apply these ISO-specific recipes. Then, I activate the lens corrections to all files at once via the Tool Palette. (After the ISO recipes, I restore the default sort order by filename, ascending.)

For your experts out there: DPP4 as well as Adobe Camera Raw have lens correction features. In my example using Canon's 24-105 version II,. both programs recognize the lens profiles. Can you tell me the difference and the advantages/disadvantages bethween the two.

Before I got my 5DIV, I only used Adobe's ACR. Adobe did not support the 5DIV files at first, and therefore I started using DPP4. Now I go back and forth, between the two for processing raw files. I seem to get good results from both but I would love to hear non-biased opinions on whether one is better than the other for processing Canon raw files.

Thanks in advance.

If you view at 100% or 200% and leave sharpening on after optimization you may see white or colored haloing around the edges. As you lower the sharpening the halos become less prominent. After applying optimization I lower sharpening a bit as needed, which is perhaps 25 to 50 percent of the time.

The difference is that the DPP lens profiles are developed by Canon for their own lenses and for use in their own software. Adobe develops their own profiles based on available information. I would tend to believe that Canon's profiles are at least as accurate and perhaps more accurate then Adobe's.

I never have understood Arite's iso specific recipes.

If one applies lens corrections in DPP, will that be reflected when the images imported into LR?

Depending on what you mean by "import".

If you mean: if I update the CR2 file in DPP, will LR see these same changes when the CR2 is imported to LR? Here the answer is NO. DPP does not use sidecars. It extends (not overwrites) the CR2 data inside the CR2 files. However, only DPP can see these extensions inside the CR2 file. No other software is aware of the data DPP adds to the file.

If you mean: If I edit my CR2 files using DPP and convert the results as a 16-TIF (or 8-bit TIF or JPEG), then YES, your edits from DPP will be seen by LR when you import the converted file type. As said above the updates directly to the CR2 file are not seen by other software, LR included.
