When I decided to use my Zeiss-Ikon camera again (before I realised it no longer worked) I couldn’t quite remember all the functions because it had been a while since I last used it.
When I originally purchased the camera from a vintage camera shop in Arundel there was never a manual included and the owner at the shop had given me a basic run through at the time of how to use it.
I therefore looked on the internet to see if I could find a copy of the original manual.
I came across this fantastic website which has been invaluable to me for other film cameras (and vintage flashes) I have since acquired.
The website is http://www.cameramanuals.org
The gentleman who runs the website, M Butkus recommends a donation of $3 (which can be done via PayPal) if you find any manual you download useful.
I personally make a donation every time I download a manual from him as I think it’s only fair as it has helped me understand my vintage film camera’s, especially when I’m unable to find an out of print hard copy of the manual.
