Indeed, that's the reason I purchased one. Many Fuji lenses suffer from fairly bad to truly awful "hotspots" that render them unusable in infrared photography, which is too bad, because Fuji bodies are readily adapted to that photographic discipline and, unlike some other brands, have an auto white balance wide enough to embrace the needs of infrared shooting.But alas, its reputation notwithstanding the 18-135 is unsuited for any IR photography in color. It is manageable when shooting IR in black-and-white, but it has a color shift vignette/hotspot that is nigh impossible to correct. Here's an example, showing OOC jpeg, jpeg after white balance is corrected, and jpeg after red-blue channel swap (a typical IR processing technique), and a black-and-white conversion, which though not egregiously bad does have a substantial brightening toward the center:[ATTACH=full]198745[/ATTACH][ATTACH=full]198744[/ATTACH][ATTACH=full]198743[/ATTACH][ATTACH=full]198742[/ATTACH]The phenomenon is consistent across apertures and focal lengths, which is too bad.I'd be interested in seeing others' pictures made with various Fuji lenses in infrared. The problem with the 18-135 was a real surprise, and a sad and expensive one.</blockquote>
