What about PhotoShop Element 2.0 made for photo work specifically?
I guess sharpen is not sufficient to overly blurred picture?

Professionally involved in the evolution of FFT as applied to medical
imaging technologies, I too was swept up in the hyperbole of that era.
Yes, FFT is solid math which, when applied appropriately to special
situations, can be beneficial. Fundamental perspective then is no less
true now and no less applicable to film photography: GIGO. Garbage
In Garbage Out of the computer. Fundamental concept of imaging
science: you can never alter the intrinsic S/N determined at the time
of acquisition by equipment and technique. You can filter a select
portion of the data spectrum for the most desired signal, but never
change the S/N.
Photoshop provides as much (maybe more) as you will ever obtain from
any of those FFT programs. NOTHING substitutes for sharp lenses, sharp
eye and the technique reminders just posted. Signal can never be
recreated by image POST-manipulation - - - one of the reasons the
publicity on these techniques evaporated.
Enjoy Photoshop (or equivalent ) and your zuikos.
