I use the TS-E17 and 24 quite a lot, and now have the EF11-24 to add to the wide collection - all great lenses
They're pretty sharp lenses to start with, but I've been testing Piccure+ as a plugin to 'fix' some aspects of lens softness.
It's not fast (over 5 mins on a 1Ds3 file), but the sharpening for lenses like a fully shifted TS-E17 is very good, and to my eye looks very much as you'd expect a 'better' lens to perform.
I've quite a few examples in some notes I've written up at:
http://www.northlight-images.co.uk/reviews/plugins/piccure_plus.htmlNote for example, the shifted TS-E17 shot of Southwell Minster. The sharpening seems a lot more natural looking than many techniques I've tried
Like any such tool it needs some experimentation to see what works best, and how it affects other aspects of my RAW file to print workflow.
There are still some types of sharpening that I'll try with focus magic, but Piccure+ seems set to become part of my 'Big print' workflow.
