Aquatech Eye Piece originally designed to fit Aquatech camera rain shields, can be easily be adapted for use with the NEWSWEAR LONG LENS RAIN PONCHO. It comes in either Canon EOS 1D series, or Nikon D1 series fittings, and provides a more secure eyepiece with its unique twist mount. *** Please note these eye pieces have a large foam surround which by design can wear with heavy use, this is not covered by the warranty but the eye piece remains usable if this foam becomes detached. ***
