Changing partly exposed films
If you want to change a film that you have only partly exposed, first rewind that film into the cassette (page 12). Rewind only as long as the reversing button rotates then stop. This will leave the trimmed film leader outside the cassette. Remove the film from the camera and mark on the cassette the number read off the film counter. When reloading the partly exposed film at a later date, first load it in the usual way and set the film counter to the diamond, then operate the rapid- wind lever with the film release button depressed until the number that you have marked on the film cassette reappears in the film counter window.
Eyesight correction
If you use spectacles but do not wear them while taking pictures and so cannot see the finder image clearly, you can order a special correction lens from your photo dealer. This lens screws into the finder eyepieces mount. When ordering please state the exact power required in dioptres +or
Care of the camera
Protect your lens against damage and avoid finger prints on the lens surface and the finder windows. For cleaning outer glass surfaces preferably use a soft sable brush or special lens tissues. From time to time also dust the film track and cassette chamber with a brush.
Filters
Filters are used with
Most filters have what is called a filter factor. This is the factor by which the exposure must be increased to compensate for the light absorbed by the filter. With the RETINA automatic I, this is best allowed for by reducing the film speed setting
as follows:
Reduce the film speed setting by the following number of divisions
