Unused PENTAX 67II Screen Grid Matte BG-80 This is a BG-80 grid matte screen for the Pentax 67II. It is unused and was only opened for inspection. The original box has scratches and scuffs. Compared to standard screens, this screen is very bright, making it easier to focus. However, there may be some exposure error with stopped-down metering. Also, the periphery may darken when using wide-angle lenses of 75mm or less. Please refer to the lens compatibility chart from the manufacturer, which is shown in the fourth photo. Thank you. ※ Photos 3 and 4 are excerpts from the manufacturer's instruction manual.
