If you are not satisfied with your manual focus lens of SLR camera, this split screen is the best aid to give you accurate focus.

Features:
Made of good quality resin, it's soft and not resistant to scratch, so please install it with tweezers carefully. When the image is correctly focused, the lines would form a straight line. Otherwise, if the line separates the circle into two halves, it means the focus is not accurate. Helps user to focus accurately in shooting. Nice replacement for worn and old focusing screen. Suitable for PENTAX KR KX KM K3 K5 K7 K30 K50.
