Efke R25 Overview

Efke R25 Black and White 120 film is manufactured using classic emulsions with very high silver content. This results in a large exposure latitude and superior grayscale reproduction. The Efke 25, 50 and 100 films are made using the ADOX formulas that were first introduced back in the 1950s.

Efke products are true to their rated speed. Unlike modern flat crystal films, which are very unforgiving to use, these films allow beginners to produce quality images. The nature of the film also easily allows large, grain free, enlargements to be made from negatives.

Made in Croatia
Efke roll films are coated on a polyester base (100 microns plus coating)
