Having a lens that is super sharp in your camera bag is a very good
thing.  You can always lower the sharpness on the lens with a Softar
filter, but when you need razzor sharp chromes use it without a filter. 
This way you have the best of both worlds.  You can remove sharpness with
a filter but nothing you can put on your lens will add sharpness thats
not there already.
