[QUOTE="BackdoorArts, post: 322984, member: 9240"] These were not profile corrected. I almost always use it, but rarely with the fisheye. Here's the fountain perspective (unedited) with the profile correction applied... [ATTACH=CONFIG]97086._xfImport[/ATTACH] It essentially turns it into a 15mm lens, but stretches and severely distorts the corners, losing a lot of resolution. There are uses for it, particularly with architecture, but you need to make sure that details are preserved where you need them. Some lenses vignette more than others (like the 50mm f/1.8), and being able to correct them is a plus in most situations, but if you like a lens for the look that it gives you then you can simply turn it off. I apply it automatically in the Develop module, so it's a bit of a pain when I have to turn it off for the fish, but it saves me clicks with all the other lenses. If you're really interested in how profile and perspective correction work with the fish, I say a LOT about it here...
