Don't worry , "off topic" happens very often , and I do not see a problem with that . This is a community , which also lives by small talk , no matter in which thread this will happen .
Now back to your topic :
I use a CFV back and my experience so far is , that different images need different sharpening . Up to now , I can not really say , which type of image needs what sharpening .
But in general , the TIFF files , I create from the 3FR raw , need a sharpening .
I use a method of two consecutive sharpenings in PSCS3 .
The first is mostly around 120/1,3 . Then I save the image . The second sharpening is mostly at 100/0,8 . The trick is , not to over sharpen the image . It needs a bit of experience , which you will get by the time . But I would like to say , that there is no golden rule .
I made the same experience when scanning LF negatives with an ARTIXSCAN 1800f .
