Pentax Spotmeter V &nbsptype_Audio 6 is a compact standardThe Pentax Spotmeter V is a precision meter for reflected light measurement. It reads from a one degree area through a big, bright viewfinder, displaying an EV number on an easy to read analog scale which can be transferred to built in calculator dial to provide exposure options. Accurate readings, excellent cosmetic condition, with light surface wear. Worth noting: the internal illuminator lamp is not functional.
