12. ot least by the confidence justified by every product of the Agfa Camera Works The vast experience of our factory has gone to produce in the Karat 36 a miniature camera of a perfect type which will satisfy all requirements Thanks to its collapsible rapid feeding lever that sets the shutter and ensures speed in setting and releasing it again the Karat 36 has become the ideal camera for all amateur and professional photographers and for all press work The idea behind the construction of this camera was to produce an absolutely fool proof camera simple in its mechanism and easy to handle But never forget that you have in your hands a first class optical instrument of precision construction and that careful treatment is no more than its due We would therefore request you to read these directions carefully They have been kept as helpful and short as possible Practice the operations in the illustrated part first without a film in the camera You will then be able to manipulate your camera quickly and steadily in all circumstances Get accustomed to switch the rapid feeding lever with an even firm jerk This will enable you to achieve maximum speed in making exposures Practice focusing too After a short time you will find that you have no difficulty in focusing even tiny objects quickly and satisfactorily Never use force Protect your camera from dust and never expose it too long or unnecessarily to sunlight Avoid touching the lenses with your

15. ture cameras minutely calculated constructions in which the most exacting demands on optical equipment for instance in color photography have been taken into consideration The coating of the lenses consists of an inconceivably fine layer on the lens surface On the one hand this protects and enhances the great transmissive capacity of our lenses as reflection losses which can never be entirely avoided are greatly reduced on the other hand it eliminates the disturbing reflexes flare spots and ghosts that are apt to appear on many pictures and on the most interesting ones in particular namely in exposures against the light It is therefore understandable that such exquisitely fine optical instruments should need most careful treatment Avoid touching the lenses with the hand and immediately remove any dirt or finger marks which are by no means as harmless on such highly polished lenses as is commonly supposed In cleaning use only a suitable piece of chamois leather or soft linen which must be absolutely free from dirt oil or dust Wind the cleansing material round your finger or over a small pointed wooden rod Never use an instrument with a sharp edge or made of metal It stands to reason that lenses with the anti reflex coating require still greater care Remember that the coating has only a thickness of about 1 1000 mm This does not mean that the coating is particularly susceptible to injury but it is just as easily damaged by wrong tr
