About Sirui Night Walker 55mm T1.2 Cine Lens for Micro Four Thirds

55mm Lens
The included 55mm lens is the S35 frame lens, which can be used in landscape, documentary, portrait, still life photograph, etc.

• Suitable for close-ups and portrait shooting (Equivalent to a 77mm full frame lens)

Large Image Circle
The maximum image circle of 55mm lens is 34mm. This lens is large enough to cover the sensor size of mainstream S35 cameras (for example, the sensor size of RED KOMODO is 30.56mm), which helps to capture brilliant images.

Ideal for Low-Light Shooting
Because of its great optical performance, the image is still sharp at max aperture. In addition, fast T1.2 aperture contributes to pleasing bokeh quality and clear subject, thus giving the footage extra expressiveness and aesthetics.

Outstanding Optical Performance
ED Glass and High Refractive Index Glass are added to reduce lens size and meanwhile provide ideal optical performance with perfect sharpness, minimal focus breathing and strictly controlled aberration.

• 1x ED Glass & 4x High Refractive Index Glass

Compact size
The minimum weight of one single lens with advanced optical construction, which creates a new era of lightweight fast aperture lens. Also, strong aluminum alloy construction helps protect inner optical elements.

• Identical 77.6mm diameter focus ring with 270 Degree rotation angle
