Braun Phototechnik is a German company which has one hundred years of tradition under their belt. Their line-up is quite wide and diversified - among other things you can find there binoculars, small camcorders, scanners and other optical equipment. Up to now we failed to test products of that company so we are catching up.

Design, usage and summary
The ring is screwed-on but very slack. It practically hasn’t been greased at all so it moves too loosely, it is uneven and loud. The surfaces aren’t coated. In the box there is a little bag with a hygroscopic substance. The filter makes a rather shoddy impression.The spectrum characteristics are practically flat across the whole visible spectrum and infrared as well. Still the extinction coefficients are weak which might lead to a violet- purple hue of damped down reflections. The filter becomes translucent in infrared very quickly.
