The Sony Eye Cup Eyecup Eyepiece Viewfinder Replacement Part is a genuine product made by Sony in Japan. Not sure if it is for the Sony HXR-NX70 camcorder, but we had a HVR-Z5U that this must have been for. It provides a comfortable and secure viewfinder experience for the user. With its compatibility with Sony brand camcorders and high-quality construction, this replacement part ensures a proper fit and optimal performance for capturing your footage with precision and clarity.
