Sirui Mars 1.33x Anamorphic Lens Set for Micro 4/3 mount is a sharp and fast anamorphic lens kit designed to bring a cinematic look to your videos. With its 1.33x Ratio, the lens takes full advantage of the 16×9 sensor crop that these cameras shoot video in to produce a 2.4:1 aspect ratio that is synonymous with theatre movie experiences.

The lens kit uses an optically distorting anamorphic front element to squeeze the horizontal axis of the shot by 1.33 times which allows for more information to be fit onto the sensor. This is then stretched back out in post-production or in-camera (see manufacturers specs for compatibility) to create the wider field of view and ratio compared to a conventional aspherical lens.

The lens kit reproduces flares beautifully whilst the coatings on the lens keep them from obscuring the entire frame. The fast aperture of T2 to T2.9 to creates a very shallow depth of field increasing the oval-shaped bokeh effect that is found in anamorphic lenses. this soft out of focus area is one of the many benefits that a true anamorphic lens brings over its filter counterparts or digital crop bars that are used to imitate the anamorphic ‘look’.

The four included lenses 24mm, 35mm, 50mm and 75mm cover a key focal range to offer complete versatility.
