Your cam has adjustable settings that can apply a degree of sharpening to your images.

Depending on the RAW software you are using...it may or may not take that in cam sharpening setting into account....ie, it may default to zero sharpening when opening the image....of course you can change it if you wish.
The TIFF shot will already have the in-cam sharpening applied.

Generally, I leave my in- camera sharpening setting to off...then use image processing software to sharpen as a FINAL step. Third party software is much more sophisticated and will give you far greater control than the in- cam engine.

BTW, as a point of interest,  I don't think there is any such thing as a true ZERO sharpened RAW...I believe it has to sharpen as part of the process.

In youth, we learn....with age, we understand.
