Therefore, it's useful regardless of the focal length of the lens being used. It's true to say the flash won't cover more than 85mm but, in this case, we're talking about angle of view, i.e. the flash will cover the angle of view of an 85mm lens. Because the 180mm has a narrower angle of view than an 85mm lens, the 85mm coverage of the flash will cover the entire scene (with, granted, some 'wasted' light). I don't mean to be picky, but Robert's sentence above might lead to confusion. Bye, Mike [EMAIL PROTECTED] www.NetworX.ie ---
