Just wanted to share the information that Efke 25 is available as sheet film, so ld under the name Wephota NP 15. It can be bought in all sizes, and if you have an odd size camera they will cut the film for you!
Efke 25 is the old Adox KB/R 14 film that was born in 1949. It's as sharp and fi ne grained as Ilford Pan F Plus! :-)
