The Konica Impresa 50 Professional is a color negative film. It has a sensitivity of ISO 50.
At launch, Konica described it as the finest-grained and sharpest color negative film on the market. Impresa 50 is developed using the C-41 process.
The Impresa 50 was discontinued by Konica and is no longer produced today. Unfortunately, there is no real alternative for the film, which was available for 35mm and medium format cameras, in the ISO 50 range.
