I thought while shooting with the "Q" in DNG we always get the full 28mm crop and the crop for 35 and 50 only affected the JPEG files. Today I decided (long overdue) to test out the resulting images from choosing the 35 and 50 crop expecting to see 3 DNG files full 28 and the difference in the crops only in JPGS. Not so... They all show the crop. So, I didn't read something correctly or something else changed???

Lightroom shows the crop selected in camera by default.  The full image is still available.  Select the crop tool in the Lightroom develop panel and you'll see the entire image.  You can more or otherwise adjust the crop if desired.

The crop info is stored in the DNG. However, LR is the only application I've found that applies the crop (non-destructively). Luminar, Apple Photos, RAW Power & Affinity Photo do not. I didn't try PS, C1 or DxO. It would make sense that PS behaves like LR.

As can be seen, the raw data's crop information can be honored or not honored per the specific application you're using to process them. IMO, Lightroom does it the right way—it honors the crop parameters but allows editing and adjusting them. I first saw this behavior when I was using the Olympus E-5 DSLR and learned how it worked then.. I think it was the first camera I owned that embedded crop parameters into its raw files that reflected the framing proportions in the viewfinder.  :) 

The Q2 crop data is stored and editable with EXIFtool and other EXIF editors;  for example:  

75mm crop:

Crop Top                        : 0.312321

Crop Left                       : 0.31238

Crop Bottom                     : 0.687321

Crop Right                      : 0.68738

28mm crop:

Crop Top                        : 0.09957

Crop Left                       : 0.099665

Crop Bottom                     : 0.900251

Crop Right                      : 0.900335

So if you want to get the full FoV to display with your in-camera cropped images, and be editable in other raw processors, edit the EXIF parameters "CropTop, CropLeft, CropBottom, and CropRight" to match the 28mm crop specifications, then open the file in your raw processor of choice, if it is other than LR. On macOS using a Terminal window, I use the command line and this command: 

$exiftool -CropTop=0.09957 -CropLeft=0.099665 -CropBottom=0.900251 -CropRight=0.900335 {filename list}

For safety reasons (to ensure against my making an unrecoverable error), I always do this on a copy of the original DNG files. :D

BTW: of course this implies that you can set your own custom crop parameters on any Q2 DNG file, any time you want.

All that matters to me is that, in my camera > card > finder > PS/Camera Raw workflow, when I choose a 28, 35, 50 (mm) crop in the Q I don't have to use the jpeg for crop information. I really only care about the images. I just thought from what I read about the Q that the crop was only evident in the jpeg. Totally my fault for not researching carefully. Thanks for the insights.
