So I took your response to mean radius =250, Amount=40% & Threshold=3 (default), etc. Based on that I created a 'Raven Sharpener' action. Here is a before and after. It certainly boosts the apparent sharpness and dehazed the image. However, I am not certain it isn't too much in this case. The butterfly was back lit and the hazy quality might be desired as part of the sense of place and time.
Woah! No, the original seems better and is actually quite good. My method has 6 steps, and none of them gets more than 8% sharpness.
All with threshold set to 0. Maybe that isn't default... I'm still toying with it.
250 pix 4%
64 pix 2%
16 pix 1%
4 pix 2%
1 pix 4%
0.5 pix 8%
Auto contrast
Different photo example with the new value; before and after. As I played around it seemed about 90% of the difference in this example is from the auto-contrast. The sharpening did add some detail that auto-contrast alone did not. BTW, these settings seemed to have little impact on the butterfly photo.
That looks more like it! They don't have a noticeable impact on all photos, but on some they have a HUGE impact. Case in point: taken from a misty mountain top in China, the city of Tai'an before and after (this was the older method, I don't know if the new one would do the same exactly):
Note that you may have to run the routine two or three times to make the effect of the unsharp mask clearly noticeable, I made it mild on purpose because I didn't always want a sledgehammer effect. The auotcontrast has minimal impact after the first run. I put autocontrast on last so I can undo it with just ctrl + z when it screws up, which happens about one time in ten.
Who says Olympus can't do high ISO? ISO 1600, 300MM on a 70-300MM. Wish I had a faster lens to push the shutter higher, but you work with what you got.

And one more... for some reason the EXIFs got stripped out of these pictures, don't know why. 70-300MM at 300MM F5.6, ISO1600, developed from RAW in Master 2
