see pictures--I noticed that the material of the lens barrel, although black, would reflect light into the lens and cause flare-the opposite of the intended effect of the lens barrel. Therefore, in went some of the telescope flocking material. Unfortunately, the flocking is self sticking and was a pain to get in there so I can't take it out to do a "comparison" shot. anyways--this works for all lenses and lens shades.every little bit counts. See pics.
