Product description

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

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 focusing is not accurate.  Suitable for PENTAX KR KX KM K3 K5 K7 K30 K50.

Fitment: for PENTAX KR KX KM K3 K5 K7 K30 K50
