I've never used Efke's sheet films, but about 15 years ago I used their 35mm and medium format films extensively and was very pleased with the results. The old KB-14 emulsion had a spectral sensitivity that differed from other black and white films in production then and now--it rendered greens somewhat lighter than other films. I loved it for landscape work. If you do order and use this sheet film, I would be very interested to hear how it works out for you.(posted 8717 days ago)
