Re: canon 17-85mm lens....Need crisper image...

Nik Sharpener is what most of the Pros are using. You need to tailor the sharpness to your output format. Print can withstand more sharpening. You can also add sharpening to a Photoshop selection so if you want to sharpen the face or just the eyes in a portrait and leave the rest as is, it's easy to do.

Nik also do a plugin to reduce grain and colour noise for digital cameras inclusing a profile built for each digital SLR call DFine. Again this can be used selectively.
