Medical ( DX 100 )
medical-scientific camera from (CONTAX)

It's a imaging device. Macro "versatile photography with a macro lens with an automatic flash and a Contax / Yashika holder.

Among the most important uses of Medical (100DX), we mention:
1 - Industrial photography, zoom (1:1 M)
2- Medical photography.
3- Dental photography, with magnification (1:1 M).
4- Commercial photography.
The helm is the foundation of the scientific method, and the principle upon which the Medical DX 100 is based. Accuracy, speed and simplicity of operation are essential for the unique necessities of medical/scientific photography.
The Medical (DX 100) is not just a lens, it is a complete device for accurate macro photography that has been designed for industrial, scientific and medical uses in particular. In fact, it's a completely new, simplified approach to the unique requirements of macro photography, with the flick of a switch. The medical (DX 100) becomes ready for use and all exposure requirements are set automatically according to the magnification rate.
It has been developed as an integral part (Contax Real Time System) that combines comprehensive accuracy with easy and fast operation. There are five main advantages of this camera, which are:
1- Continuously changeable magnification:
A screw focus system provides continuously changeable magnification rates from 1:1 to 1:15 - from true-scale close-ups to half-shots
Scale - Smooth focus movements make the Medical DX 100 as simple to use as a standard viewfinder, and the wide magnification rate can be extended to twice the true scale by attaching a 2X Conversion Lens.

2- Automatic exposure adjustment:
At every magnification, the Medical DX 100 produces typical exposure images.
Thanks to the stable output of the built-in ring flash unit and the diaphragm mated to the screw focus system, accurate exposure is expected in keeping with the chosen magnification, and even when held hand-held without a tripod the Medical DX 100 takes exemplary images with sharpness. , thanks to the super-strong 1/1500-second flash that freezes even
The simplest movements, and since the diaphragm is coupled to the zoom, the main subject is always correctly exposed, even when subjects in the foreground are interfering.

3- Appropriate working distance:
It often happens that medical or macro lenses require working distances that get in the way of the task at hand, and the Medical DX 1000 is designed to allow adequate working distances at every magnification, from working at an actual scale at 14.7cm to a 1:15 magnification at a distance of 1, 5 meters from the subject. The lens also provides a natural image without a noticeable deviation in the dimensions.

4- Flash photography free of shadows and reflections:
Shadows disappear completely in the Medical (DX 100), thanks to the built-in ring flash unit that gives proper and even illumination of the main subject. The newly developed Val-Reflec (tor Set) allows achieving photo exemplary images even of highly reflective subjects, previously impossible with ring units. - Another flash, because only this camera can confirm that a photograph has taken place
Typical photography free of shadows and reflections every time. Also, the accurate color representation achieved despite the additional illumination of the room, is another important advantage of this electronic flash that protects subjects from the ill effects of heat.

E - accessories and a ready-to-use bag:
The medical device (DX 100) is completely assembled in a ready-to-use box, in which the camera body and DC power pack are connected and ready for immediate use at any time and anywhere - in addition to this, the box also includes a camera winding unit: and there are other accessories available to expand the field of activity Photographer.
