Practica ( 50 MTL )

If we take a look through the Practica 50 MTL viewfinder, we will be amazed at the scale of the brightness in the image.
Frame making, pinpoint focus and signature depth of field...these can all be easily accomplished without taking this 35mm SLR camera out of sight.
The extraordinary luster and luster of the viewfinder is due to the Fresnel screen, whose various fields ensure the best possible focusing accuracy.
The unique feature in - Falaqa. The triple pointer is that vertical and horizontal acros can be focused with equal precision without having to rotate the camera. If the image is out of focus, what we see in the middle wort will be outside the pavement with the two lateral cotyledons.

Correct focus will produce a coherent image. In addition to this, the triple cotyledon is surrounded by a fine prismatic lens ring and a granulated glass ring. We use these two as an additional focus aid for special subjects. The Practica (50 MTL) is equipped with an automatic exposure system.

Either aperture or shutter speed is pre-selected and the other value is paralleled by the LED assembly in the viewfinder; a new feature in the Practica 50 MTL. The two LEDs will flash as soon as the correct shutter speed or aperture is signed.
Then the necessary work is done during the bag on the expression switch which is appropriately placed next to the firing button, while only one LED will light in case of over or under exposure, so that false exposures become non-existent.

This Practica (50 MTL) is supported by a wide range of interchangeable lenses to suit individual needs.
Well-made lenses with (1 x M42) Practica tape used worldwide, and focal lengths ranging from 20 mm to 1000 mm, make it easy for creative works to exceed all limits.
These lenses have great optical advantages such as high resolving power, better contrast reproduction, distortion-free, color fidelity and the lenses are all multi-coated to reduce reflection and satisfy all the needs of precision photography in versatility as well as from a mechanical point of view it is a new world opening up to unimaginable beauty Picture it when using accessories working closely with the camera. This means that the many accessories available for the Practica 50 MTL expand its range of applications enormously.

The available pieces are suitable for close-up works, micro works, reproduction, slide reproductions, and science-technology photography. These include the following:
Bellows connections, extension rings, copy stand with illumination, slide copy unit, micro adapter, astronomical adapter, plus an angle finder, eyepiece, and zoom lens are also available as focus aids.
However, the use of interchangeable lenses and accessories with the cameras never restricts this camera's versatility. As usual, the framing and focusing of each subject are appropriately made with the help of the viewfinder. Then, if accessories are added or not, the automatic shutter speed adjuster will confirm that it was made. Accurate exposures at any time.
