<p>Not exactly what you asked for but perhaps, interesting nonetheless. I use a 45 PCE on a D300s, the <a href="http://patwarner.com/new_pix.html">first 20 or so pix,</a> tilted and shifted as needed. Clean and sharp? As good as can be for the WWW. I use the lens for nearly everything. Some compromises, but max versatility. One thing, seems you're after speed. It is a fast lens alright, but the set up never is.</p>
