I've processed all my NEF files using the free trial period, and am waiting to buy the mid-range product. Out of the box it has substantially sharpened up my Sigma 18-200 pics, correcting a lense and camera combination (on a D50) that consistently produces noticeably soft images when wide-open and at high ISO. And once I got the hang of it, I found its photography controls easy to use to adjust raw settings. I like also the fact that it can export DNG files as well as or in place of JPEGs. Anybody else using it? If so, with what camera and lense combo?
