I have both. The 14mm is in my box of lenses I plan to sell one of these days. I can't comment yet directly on anIQ comparison; my preference for the 15mm over the 14mm is simply size. I don't use wide angle that often, so carrying around a small lens for that just-in-case moment makes more sense to me than carrying around a larger lens.
I have a nearby industrial scene I will do nighttime shots of; I'll send you a link to some comparison shots in the next few days. Meanwhile, you can see a pano of the scene stitched from 15mm shots: http://smhalpin.posterous.com/?page=4# at the bottom of the page. stan On Dec 18, 2011, at 8:25 AM, Ralf R.
