Do you want to take top-quality photos with your smartphone? Then you need the lenses produced by SIRUI.

SIRUI lenses are supplied with a dedicated adapter (supplied separately) and are not attached using clips or magnets as with other manufacturers’ products. Professionals do not use all-in-one lenses, they use fixed focal lengths which let you take the best photos. Smartphone photography means: high quality photos with your smartphone. Obviously, SIRUI lenses are also suitable for video use.

Our lens attachments are more than just magnifying glasses. They are composed of several glass lenses made of German Schott glass. They have multi-layer, anti-reflection coatings. These minimise reflections and increase light transmission. The lenses guarantee accurate colour reproduction and offer minimum distortions and vignetting. Image sharpness to the edge of the picture is guaranteed.

What is the SIRUI 18-WA?
An 18mm wide angle lens for your smartphone. It helps expand your creativity.

What can the SIRUI 18-WA do?
With its 95° field of view it captures more of your world than your smartphone lens. You get 50% (0.5x) more of your subject.

For even more creativity using the wide angle lens, the 18-WA-CPL circular polarising filter is also available. The polarising filter provides you with unbeatably strong colours, especially for landscape photos. The sky becomes a dramatic blue, the green of plants becomes bright and detailed. Another great feature of the polarising filter is that it reduces or blocks reflections from non-metallic surfaces such as glass or water.

How do I use the SIRUI 18-WA?
A SIRUI adapter (supplied separately) is fixed to your smartphone. The 18-WA can then be attached to the adapter.
