gotcha, that clears it up. I do have a zoom through lense then. The black edges disappear once I zoom in a bit. Just wish there was a lense that didn't have those black edges so I could get the best of both worlds, ie. being able to zoom all the way out and get a full stage shot, and then be able to zoom way in on the hands/fret....all with a standard 10x optical zoom from a pretty far distance. Guess thats just a fantasy!
