SIRUI 35mm F1.8 Anamorphic Cinema Lens 1.33x APS-C, M4/3 Mount

Product Information

The MFT-mount 35mm f/1.8 Anamorphic 1.33x Lens from Sirui is designed for MFT/APS-C cameras and increases the horizontal FOV by 33% in comparison with traditional 35mm APS-C lenses. The result is equivalent to a wider 26.3mm APS-C lens. After de-squeezing, the captured image is displayed in an anamorphic 2.4:1 format in a 16:9 setting. This fast f/1.8 lens is designed with an aluminum housing and features optics with multilayer nano coatings. Made with renowned Schott optical glass lens elements, it produces rectangular aspect ratios, long horizontal lens flares, and oval bokeh. Anamorphic lenses are sought-after by filmmakers due to their ability to capture a wider field of view given a specific image area height. Anamorphic lenses squeeze the frame from the sides, resulting in what appears to be a distorted image. However, it’s possible to stretch the image area to a wider aspect ratio when de-squeezed during post-processing. In the case of the Saturn lens, even though it’s designed for 3:2 aspect ratio full-frame image sensors, it can capture the field of view of a 2.4:1 or 2.8:1 aspect ratio while using the full height of the image sensor.

Some cameras, like recent Panasonic mirrorless cameras, can even offer a de-squeezed preview when shooting, which makes it easier to compose scenes. Without such a feature, it can be challenging when working with an anamorphic lens, given that everything looks squished in the viewfinder. At its closest focusing distance, the squeeze factor of the lens becomes a bit distorted, and a full 1.33x de-squeeze will slightly elongate the image horizontally. In these cases, a 1.25x de-squeeze factor can be used instead. The closest marked focus distance on the lens is 0.6m (2 ft), but users will find the anamorphic effect is somewhat diminished in images shot at this end of the scale. Applying the marked 1.33x de-squeeze to footage will leave your subjects perceptibly elongated. The lens is native to the MFT frame, and can basically cover the APS-C frame after using the adapter ring. If you need to use it on a full-frame camera, please turn on the APS-C frame mode on the camera body, and you can use it normally.This video includes sample footage shot using the Panasonic Lumix GH5, GH5s, and BGH1 in 4:3 anamorphic mode, and 16:9 and 17:9 aspect ratios to achieve different final looks.

Designed specifically to work with the MFT mount on the lens, this is a semipermanent lens mount adapter that fits on your lens’ MFT mount and is attached with four screws using the included fine-tipped screwdriver. Please note, once your lens is adapted, you will need to switch full-frame cameras to APS-C to avoid vignetting.One of the features of this lens is that it produces horizontal blue streaks with less stray light, which Sirui calls sci-fi horizontal flares. A key aspect of anamorphic lenses is highlighted oval bokeh, and this lens produces a shallow depth of field and oval bokeh with its 10 aperture blades. While the lens has a robust housing, it’s also designed to be lightweight for use with your compact MFT/APS-C camera. Sirui 50mm f/1.8 Anamorphic 1.33x Lens (MFT Mount)

Made with renowned Schott optical glass lens elements, it produces rectangular aspect ratios, long horizontal lens flares, and oval bokeh. One of the exciting features of this lens is the close focus distance of just under 2′, allowing you to get close focus for creative effects. Focus scales marked in both feet and meters makes this well suited for users around the world, and the 72mm filter thread is a popular filter size for adding filters to your lens. Sirui 35mm f/1.8 Anamorphic 1.33x Lens (MFT Mount) The horizontal equivalent angle of view of SIRUI 50mm anamorphic lens is 37.5mm, and that of view of 35mm anamorphic lens is 26.3mm. In contrast, the depth of field at the 50mm focal length is shallower, and the oval bokeh is more obvious; the framing field at the 35mm focal length is wider.Cropping will destroy the original composition, waste material on the top and bottom edges, and seriously lose image quality. After installing the SIRUI 35mm/F1.8 1.33X anamorphic lens, the sensor area can be better used, 33% more material in the horizontal direction, and 2.4:1 wide-format works can be output without cropping.
