Dear Patric, absolutely. The Maco films are made by Efke. The IR 820 is based on the Efke 100. The ORT 25 though is not a Efke 25, which is orthopanchromatic and is calibrated for a normal contrast range. The ORT 25 is closer to a high resolution orto microfilm on a "conventional" base, exactly what the Agfaortho was. Some people again might come with the old story: Maco is in Germany and Efke in Croatia. On the films it says "made in Europe". It is funny when you compare a Efke and a Maco 120 film side by side. The machine that fixes the end paper to the film is obviously misaligned in Zagreb: The paper is glued to far away from the edge of the film, which means that it is impossible to secure the film without taking the entire paper off: Exactly the same can be seen on the Maco film.(posted 8276 days ago)
