I don't go into DPP at all...
Everything comes into LR, and converted to DNG immediately....and I work from the DNGs, not the CR2's
I use LR mainly because of it's cataloging capabilities...Going into DPP adds a couple extra steps to my process.
I also don't sharpen at all in LR... unless it's a quick turnaround job that doesn't go into PS.
All of my sharpening, on retouched files, is done in PS, and it's done meticulously, and they are saved as separate files.
Now... My workflow is different from others, and is designed around security, precision, and future proofing.
If you are looking for quick and efficient (as far as taking as few "clicks" to output files), then Yes I do apply sharpening in LR...but this only goes to client proofs, and or lower end clients. I find, depending on the framing/type of shot, that 45, with a 1.5 radius in LR does a passable job for this case.
Again... going into DPP adds more steps I don't need.
I don't have anything against DPP, and it does some things pretty well, but it all boils down to how you choose to work.
For me, it's a step I need not take in my work. For others...its invaluable.
in summary... I think ALL digital files require unique sharpening, when you get down to the nitty gritty pixel peeping level of analysis.
If you really care about getting the best possible results, you have to take time to achieve them.
If you want fast and efficient... you have to make compromises... regardless of the camera you are using.
