5. the 1960 PHOTOKINA the world s largest photographic fair in Cologne Germany it attracted the instant and close attention of photographers and photo graphic engineers alike Not available for purchase at that time it was a model of the advanced design and features that would be incorporated into cameras of the future Pentax cameras and other brands as well Several years of extensive research preceded its introduction and four more years of research and experimentation followed before the meticu lous Pentax engineers and technicians felt the camera was truly ready At last in late 1964 it reached the eager hands of serious amateur and professional photographers around the world Like that early Spotmatic your Honeywell Pentax SP 500 is a computer camera Hidden within its body its unique behind the lens exposure meter utilizes two highly sen sitive Cadmium Sulphide sensors to accurately measure the light gathered by the camera s lens as it is reflected from the subject being photographed Therefore by measuring the light as it passes through the lens and match ing the exposure needle as seen through the viewfinder you can be as sured of properly exposed pictures under all but the most impossible light ing conditions Whether you re using special macro or microphotographic lenses telephoto lenses or simply filters on normal lenses your Honeywell Pentax SP 500 will give you correctly exposed photographs without the use of ex
