A more sophisticated model of the Kodak instant film cameras. Kodak used their own film, PR10/PR144, which had to be removed from the market due to law issues with Polaroid. They were produced between 1978 and 1980.
The EK300 has an additional flash, which is activated by sliding it to one side.
It's equipped with a focussing 137mm f/11 lens and full automatic shutter speeds ranging from 1/20 to 1/300 sec.
Also known as the "Colorburst 300".
