Adox 300

The Adox 300 is a 35mm viewfinder camera made by the German company Adox and introduced in 1956. It was one of the few 35mm cameras to be equipped with interchangeable film magazines, allowing one to change film-type in the middle of a roll (other examples were the Zeiss Ikon Contarex, some versions of the Zeiss Ikon Contaflex, the Rollei SL2000F and SL3003, the Kodak Ektra, and the Mamiya Magazine 35).
