PRAKTICA lenses - for creative picture composition

The performance and versatility of an SLR camera like the PRAKTICA can only be exhausted when exchangeable lenses are used. Without changing the camera-to-object distance, exchangeable lenses make it possible to pack plenty of details into a frame at a relatively small scale or pick out one detail and fill the frame with it, thus individually controlling picture information content and artistic expression. The wide range of exchangeable lenses from PRAKTICA multiply your photographic possibilities and provide an excellent basis for creative photography.First-class lenses have been developed for all photographic fields. Highly refractive glasses with multi-coated surfaces to reduce reflection enhance the contrast and definition of your pictures and prevent glare, aperture images and light patches even when taking against-

the-light pictures with extreme brightness differences. The lenses do not only provide sharp definition and optimum contrast but the pictures obtained with them are also true to colour. PRAKTICA lenses with large f-numbers make it easy to photograph with relatively short exposure times even under poor lighting conditions and without the use of a flash unit. Two of the particular mechanical features worth

mentioning are the unusual long worm of some lenses and the automatic diaphragm system considerably shortening the readying time for the camera drive .

Standard lenses

These lenses, being the nucleus of your optical equipment, cope with the major part of all the pictures you take for their angle of field and, thus, the information contained in the picture is very much like that gathered by the eye.The same is true of the perspective reproduction. They are therefore suitable for a great variety of photographic fields, for example for snapshots of children and animals, taking pictures of groups of persons, photographic reportages, sports, landscape and architectural photography. However, should you desire to depict more details of an object or bring it nearer to you without changing the distance to the object, then have a try at a PRAKTICA exchangeable lens disclosing the wide-angle and telephoto ranges.

Most of the PRAKTICA standard lenses occupy an unexcelled special position. Their long worm drive allows close-up focusing to 33 cm and 35 cm without any accessories. This means that objects of the size of a postcard will fill the frame.

Wide-angle lenses

You are sometimes faced with the problem of not being able to photograph a subject, say a group of people, from a distance long enough to get them all into the frame. In other words, the angle of field of your standard lens is too small. A wide-angle lens is the remedy. Its large angle of field packs more into the frame than a standard lens and its perspective is more extended. Owing to its superior information content, a wide-angle lens is indispensable when taking overall views of buildings and landscapes (panoramic shots), groups of persons, and above all when taking pictures in museums, galleries, exhibition halls and the like. The enormous depth of field and. consequently, easy focusing make the wide-angle lens ideal for reportages and sports photography as well as for other snapshots. Wide-angle lenses image objects near the camera relatively large whereas distant objects are rather small so that they lose significance. Thus, there is a clear distinction between foreground, middle-ground and background, and the perspective is emphasized. A super wide-angle lens converts a small room into a hall. The distance between foreground and background is apparently extended. This perspective phenomenon can be made use of in a creative enhancing or weakening of the effect of an object.

Telephoto lenses of medium focal lengths

If you cannot get closer to an object you want to photograph larger than it is possible with a standard lens, then use a telephoto lens. Technically, this is the reversal of wide-angle photography.The long focal length and the small angle of field seem to bring the object closer to you so that the frame is better utilized. Telephoto lenses of medium focal lengths have a pleasant correcting effect on the perspective. The object focused on is separated clearly from the unsharp background. Persons are shown in landscapes and architectural photos in proportions we are accustomed to see. These lenses are especially recommended for portraits as perspective distortions do not occur but

they are also suitable for still lives. A remarkable advantage of some lenses of medium focal lengths and all lenses of longest focal lengths is the practical adapter permitting the lenses to be mounted on various camera types.

Telephoto lenses of longest focal lengths

Their versatility is similar to that of lenses of medium focal length but they already show clearly the advantage of longer focal lengths. They bridge long distances and bring details into the frame you would hardly notice with a standard lens. Therefore, they are ideal for photographic reportages, wildlife and sports photography, and also for scientists who appreciate them for their capability of delving into realms that are almost beyond reach. The image scales and perspectives obtained with lenses of extreme focal lengths allow to produce unusual effects.
