Interesting this is brought up. I used to carry my Minox B everywhere. Got some great photos. They really are a precision camera. Walter Zapp had to be one of the really great camera designers of all time. My Dad used to use an Adox asa 10 film, and could make creditable 8 X 10 prints. Too bad that film isn't available any more (at least I don't think it is). This gets me thinking I should use my B again.
