Coming to market in 1973, the Spot F, as it is usually known is completely mechanical except for the meter which requires a button battery of 1.35 - 1.5 volts. We are using a 625 which works well. Being a screwmount (M42) body this opens up a wide range of legacy Pentax top quality lenses. Very stylish black body. Our example here is Japanese manfactured in A+ cosmetic condition and operational in all aspects including the light-meter. Fresh battery for NZ purchaser and pdf manual.
