Nice Filter
By Gregory A Ferdinandsen
UV refelected photography is very much a niche. Since this filter lack's reviews, I figured I'd add one.This filter is constructed as good as any B&W filter, it's thick, heavy, and screwings in cleanly. No complaints about quality.Since you can't compose a scene using this filter, it only passes 320nm to 385nm, and only when looking at the brightest light can *you* see anything. Also, you can't use it in live view (like the R72 filters by Hoya). So after composing and focusing, you have to put the camera in manual mode and dial in an acceptable image. Obviously, a tripod and cable release is a requirement. But if you are looking at this filter, you probably have both.The only reason I give it four stars and not five, I was hoping to get more artistic shots with it. I was hoping that like an R72 it might change the colour of foliage, but it does not (that I have found thus far). Also, much to my surprise, the image in very red, like an R72, even though this blocks all but the most violet of violet of light.I plan to play with it some more, maybe try it under a black light, play with it in an urban and rural settings. I think it has potential. But I would not advise getting one unless your camera bag is full. For the money, you would be better off buying something that would get occasional use than something that get rare use.
