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

Product Information

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) As an example, compared to a traditional 50mm APS-C lens, the Sirui 50mm f/1.8 1.33x Anamorphic lens produces a cinematic 2.4:1 widescreen video with a 33% increase of the horizontal field of view, effectively achieving a FOV equivalent to an APS-C 37.5mm lens.

The lens weighs about 700g and has a length of about 117mm; 13 lens elements in 9 groups, 10 aperture blades; apertures from F1. 8 to F16. The aperture is a stepless; the focusing method is purely manual, the closest focusing distance is 0.85m to infinity, and the stroke is about 191.2°; the original M4/3 format of the system can basically cover the APS after adapting to the APS-C camera through the adapter. Although the SIRUI anamorphic lens is mainly used for video shooting, it still has the function of shooting wide-format high-resolution photos, which can meet the needs of users for film-like photos. In addition, SIRUI specially customizes the focus gear and aperture adjustment gear, and presents them as accessories to buyers, so that everyone can use them selectively. This new 24mm F2.8 is intended to fill the wide-angle gap in Sirui's range of 1.33x anamorphic lenses for APS-C and MFT systems, and in doing so creates a set that comprises wide, standard and mid-telephoto focal lengths. The set now consists of this 24mm f/2.8, a 35mm F1.8, a 50mm F1.8 and a 75mm f/1.8. The 24mm F2.8 is the third in Sirui's line of low-cost crop-sensor 1.33x anamorphic lensesConvert your Sirui 35mm f/1.8 anamorphic lens from MFT to Sony E mount with this swappable Sony E Mount Adapter/ Nikon Z Adapter/ Canon EF-M Adapter from Sirui. At present, the two anamorphic lenses launched by SIRUI are mainly aimed at the huge mirrorless market, so they are also aimed at the mainstream mirrorless camera mounts, and there are currently no mounts for SLR or professional movie cameras. 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. As has been the case with the previous Sirui lenses, if you were hoping for 'cinematic' vignetting, you'll need to find out how to add it in post, as the 24mm offers pretty even illumination right across the frame. This is good news for most, as adding corner shading for atmosphere is always easier and preferable to removing it when it isn't welcome.

Quality built with innovative optical structure and German Manufactured Schott optical glass lens elements, the anamorphic lens minimizes the optical distortion and lens breathing effects and perfectly functions to generate sharp high-resolution images.

While anamorphic lenses became popular in analogue filmmaking, as cinematographers explored the visual impact of the wider CinemaScope aspect ratio, they have enjoyed a surge in popularity among digital filmmakers who want to use the best cine lenses available. No longer do you need an anamorphic projection lens to correct the squeezed image; now this can all be done in post-production.

When the image desqueezed, the bokeh behind the subject will stretch into an oval shape to create a dreamy filmic look to captivate the viewers. The screen ratio of most cameras is 16:9, and the SIRUI anamorphic lens is squeezed into the 16:9 screen by shooting at a 2.4:1 ratio, so it is necessary to enable the anti-squeeze mode on the camera body, and choose 2.4: 1 scale to view. If the camera does not have this option, you need an external monitor (such as ATOMOS) to select 2.4: 1 ratio or 1. 33x anamorphic ratio for viewing. When you are used to seeing the same 16: 9 photos, the photos taken by the anamorphic lens may bring you a unique movie look, and the 2.4: 1 wide format is closer to the perspective of the human eye, giving you an immersive feeling. Limitations in close focusing mean you will probably want to use dioptres such as the SLR Magic Rangefinder if you want to focus closer than 2m or so. And because the adapter will probably weigh as much as your lens, you will need some kind of lens support. However, setup can be extremely fiddly. Firstly you need to make sure the lenses you already have are compatible – with a native 62mm rear thread the SLR Magic Anamorphot-50 2x adapter is only suitable for lenses that have a front element size of 50mm or less.

Capture cinematic widescreen images when using a cine camera with an MFT or APS-C sensor size with this 75mm f/1.8 1.33x Anamorphic Lens from Sirui. The lens features a Micro Four Thirds mount and captures a widescreen 1.33x anamorphic image squeeze with an ultra-wide 2:4:1 aspect ratio when used with an APS-C sensor size. This design gives you a 33% increase in the horizontal field of view for a beautiful cinematic widescreen look. 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. 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. 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 achieves 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 APS-C camera. Sirui 75mm f/1.8 1.33x Anamorphic Lens (Micro Four Thirds)
