Now you can see the Glaswerk Lens Dealer in Spain and Portugal


Grau Luminotecnia was born in 1984 and since then it has constantly evolved to meet the needs of the market, always betting on the latest technologies. In the beginning, the company specialized in the commercialization of lighting for video, film and television, later incorporating dollies, cranes and hot heads.

With the turn of the century and seeing the logical evolution of the television market, Grau Luminotecnia incorporated suspension systems to its offer and, consequently, began to offer its own engineering set-up installations, being today the main activity of the company. at national level as INTERNATIONAL. Also, as lighting specialists we were introduced to the architectural market, focusing on museums.

In the decade in which we live is where Grau Luminotecnia has made the greatest evolution addressing fields such as robotics and virtual studies, going through a full range of camera accessories, including the DSLR world, and 3D rigs for stereoscopic recording. Also in lighting has made a great leap with all the latest equipment with LED and Remote Phosphorus (RPT) technologies.

Question of IMAGE. In addition we have also evolved as a modern company and close to the user with a blog where we keep you informed with three weekly news, daily presence on social networks Facebook, Twitter and LinkedIn, the iLuz application for mobile phones with a lighting database, TuttoGrau tutorials, and open houses, workshops and presentations.

Now we also have rental service of lighting equipment and camera accessories, always based on the latest technologies available in the market. We also offer for rent and sale the GoPro cameras with more than 100 accessories for anchoring in any place and circumstance, opening the door to the action, adventure and sports markets.

In summary, in Grau Luminotecnia we offer you SOLUTIONS.


After a careful development process that has lasted three years, Glaswerk Optics presents one of the most interesting professional optical film offerings on the market: its Glaswerk ONE and Glaswerk ONE + ranges. They constitute two games that incorporate frontal anamorphic elements - with an anamorphosis factor of 2x - designed to cover any of the existing large format variants (both Full Frame and VistaVision).

The Glaswerk ONE range has a maximum aperture of T2.4 and includes focal distances of 25, 32, 40, 50, 60, 75, 100, 135 and 180mm.



The Glaswerk ONE + range has identical apertures and focal lengths, but incorporates special coatings that produce the classic internal reflections based on the traditional anamorphic optical designs of the 50s and 60s. Its main differences from ONE are:

-Horizontal blue inner reflections
-Minimized spherical internal reflexes
-Contrast slightly lower
-Internal color reflections customized at the customer's request

Indeed, the ONE + allows the user to choose the color of the horizontal flare, which derives from the width of the coating that is applied to two of the cylindrical elements located in the optic core. By default, they produce a blue flare (as it is the most demanded color), but it can be customized to suit the client. As only two of the 18 elements of the optical block require this coating, the ONE + continue to offer a higher contrast than the vintage anamorphic optics of the 60s.


A quick summary of the main features of these games would be the following:

-Extraordinarily natural skin tones
-Coverage of the most common large formats
-Great image quality
-Total absence of the zampabollos effect
-Accurate mechanics with strict tolerances
-Games available with PL and LPL mounts

The Glaswerk One are optical with an authentic anamorphic front element and a 2x horizontal compression throughout the focus travel, prepared to cover the sensor of the ALEXA LF ​​and ALEXA Mini LF in Anamorphic Open Gate mode (30.65 x 25.54mm) . All cylindrical elements are located in front of the diaphragm.

The bokeh is smooth and with an oval shape uniform from the center to the edges, without spherical overcorrections. The lenses do not contain supports that correct or cut the light path. This kind of design not only prevents changes in shape in the bokeh, but also prevents large losses of brightness at the corners of the image. The Modulation Transfer Function (MTF) shows great contrast in the entire image with minimal geometric distortions and loss of brightness.
