Is in-camera sharpness the same as sharpening in post?

[PajamaGuy]

(for the "Do-a-search" police, I've been searching for a tad over 90 minutes..and a simple URL pointing to a definitive answer will be appreciated as much as a detailed treatise.)

Preamble- serious, but amateur, T3i moving to T6s (maybe 7d next year), and all lenses less than $500 - mostly jpg, but will shoot RAW + L occasionally. 

For JPG shooting:Is In-Camera sharpness 0-to-7 the same as the sharpening in post? If you're going to PP anyway, does in-Camera sharpening provide a benefit that cannot be obtained in post?  Is there any disadvantage to using in-camera sharpening? 

Thanks for your time!

Grampy,

Sharpening does not sharpen anything.  It outlines edges.  So if you 'sharpen' in both place all you are doing is increasing that outline.  A lot of folks do it to the extreme!  Why? Who knows but it isn't good.  No matter how much they think it is. Maybe they mistakenly think it conceals a poor lens.  All the editing features in post should be done at the least level possibile to improve the image.  In this case more is not better.  It is an example of less is more.

Did you state what camera/lens you are using? There may be some technique changes you need to make that will help.
