Emaks and Varycon papers are great stuff. I haven't used them for years though, since they aren't available in Sweden anymore. It's sad to see them vanish from the market.
The Efke films are popular and it's a relief that FK will continue to make them. There has been talk over the years about moving the production back to Germany and Adox, so these emulsions will probably still be made even if FK decides to quit.
