I would like to present a photographic filters of my design.
It is a bokeh shaping filter, which has got the standard lens size used in photography.
The conventional sizes made by me are as follows: 52, 58 , 72 and 77 mm. I also create filters in other sizes and filters for non-standard lenses (like Leica or Hasselblad), but you can also make them fit by using step down/up rings or adapters .
The filter has got a revolving front part, which is a very important feature when switching from landscape to portrait format, or with lenses that do not use internal focusing .
It is easy to maintain a correct position.
This design also lets the user achieve motion (rocking/revolving ) effects in filming.
The standard design of the filter allows the user to attach other modules,e.g. : cookin holder which creates new possibilities.
