Hi I am looking for a all matte minolta focusing screen without any focusing aid, i.e. without any little circles or rectangles in the middle. Preferably of the acute matte spherical type. I believe they were made for the XD, XM, X700... but it's soo hard to find them now. It's not important for which type of minolta body the screen is. Please if you where to find them, let me know. Thanks!!
