The < FAVOR > minia'lure camera has been designed especially lor use wilh any slandard 35 mm lilm;
packed in normal day-li9ht magazines conlaining 35 or 12 exposures. lls body is made ol a lighl alloy die
casling prolecled by means of a chemical process againsl corrosion and ofher a'lmospheric inlluences. Top,

As shown in lig. 1, a Pronlor-5-Shuller (1) combined wilh delayed aclion release serves _for arranginglhe exposure limes and lhe aperlures. The oplical elemenls having undergone an anli-relleclion llare-

The lenses have been coafed wiih exlreemly lhin blueish layers in a specia'l vacuum process, by means ol
which the relleclion losses encounlered up lo now on glass surlaces have nearly been complelely avoided.

II. HOW TO TAKE PICTURES. A GENERAT OUTLINE

Any slandard 35 mm lilm packed in day-light magazines can be used. Turn the key (10 fi9.2) on lhe

lhe suilable sellinqs in due order :

Furlher lorcible moving may resull in damage fo the film locking mechanism.

row re-inserled as described above, A loss ol 2-3 piclures is, however, unavoidable.
Inserting the back lid
. Make cerlain lhal on inserlion ol lhe back lid, lhe key of fhe lid locking device shows downwards,

REYIEW - To have a good conlrol ol the resulls oblained il may be uselul lo pass the film under a
magnilying glass (a'l leasl B X ) an operalion which lells clearly whal sorl ol mislakes have been made.
(Giain size, -developing, selling, elc.)
For comparison lesls each camera is accompanied by a photography showing ils lens number and lhe
maximum of precision possible, The piclure laken al a dislance oi 3 mefers shows clearly thal fhe black

This lesl is carried oul on a line grain f ilm ol 27 - 28o 5ch. E. The same precision is af lainable al all
occasions, if lhe slandard rules and proper malerials are applieci. Unsharp piclures are in almosl all cases

Thus, conlrol enlargnrenls whelher lhe delails are reproduced properly and whelher lhe sharpness is
