(maybe do not letting it degrade by the side light?) Yes, it does. At least, some of them do, some of the time; in cases where there would have been a problem, but the hood manages to cut enough extraneous light to make a difference. You know how you sometimes shade the lens with your hand to block really bad visible flares, or flag lights on the set to keep them from shining directly into the lens? Same thing. For a wide-range zoom it's not going to do anything much except at the wide end, of course. -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
