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

Product Information

Included with the lens is a hard transport case and 15mm rod lens supports. The SLR Magic's Anamorphot Cine 352XMFT 35mm lens is also available as a set, together with the 50mm T/2.8 and 70mm T/4 MFT lenses (also available individually). For PL mount users there is a similar range, which features an anamorphic squeeze of 1.33x. What is an anamorphic lens? Compared to general camera lenses, the SIRUI 35mm F1.8 1.33x Anamorphic Lens can easily produce a cinematic widescreen look for users without post-cropping or using additional tools to highlight their creative shots.

With anamorphic lenses, you will often see a 'de-squeeze factor' next to the name – most often 1.33x, 1.8x, or 2x. This is because the lenses produce an image that's compressed in width and require it to be stretched in post to be properly displayed. The de-squeeze factor tells you how much the image is compressed. Some high-end cinema camera manufacturers such as Red feature in-camera anamorphic settings, allowing you to see a de-squeezed image on the screen as you shoot. 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. The 35mm lens can attach to an M4/3 mirrorless camera and fit onto an APS-C mirrorless camera with a selection of E, EF-M, and Z lens mounts by attaching the optional adapter rings. 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. SLR Magic's Anamorphot Cine 352XMFT T/2.4 lens is a35mm 2x anamorphic cine lens to fit MFT cameras which, when ‘desqueezed’, produces the full widescreen look with a real 2.66:1 aspect ratio. The lens has the widest aperture of T/2.4, features geared focus and aperture rings, a minimum focus distance of 1.1m, and 82mm front filter thread that allows you to screw in filters and dioptres to reduce the minimum focus distance. The front of the lens rotates as you focus, however, which may affect your choice of matte box.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. Well-built with an innovative optical lens structure and German-manufactured Schott optical glass lens elements, the anamorphic expert lens minimizes optical distortion and lens breathing effects and functions perfectly to generate superb cinematic imaging.

The 35mm Anamorphic Lens is solidly constructed with aircraft aluminum alloy and a precision CNC machining process. 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. This portable lens also excels at controlling chromatic dispersion to produce unique visual characteristics and provide sharp, high resolution images.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.

The 35mm lens can attach to a M4/3 mirroless camera and fit onto a APS-C mirrorless camera with a selection of E, EF-M, Z lens mounts by attaching the optional adapter rings. (*Switch to a APS-C format when used with a full frame camera.) 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. With Sirui's special adapter ring, it can be adapted to Sony E, Canon EF-M, and Nikon Z-mount cameras. Since the APS-C format camera is converted, the horizontal equivalent focal length is (35*1.5)/1.33=39.4mm, and the vertical equivalent focal length remains unchanged, which is 35*1.5=52.5mm. 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.

Sirui 75mm f/1.8 1.33x Anamorphic Lens (Micro Four Thirds)

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. After much teasing, Sirui has finally launched its second anamorphic lens for interchangeable lens systems. The first was the 50mm F1.8 1.33x anamorphic that came out at the beginning of this year, and the company doesn’t seem to be wasting much time getting its second model out to the market. This 24mm f/2.8 Anamorphic 1.33x Lens from Sirui, in an MFT mount, brings a wide-angle feel to your anamorphic imagery, in addition to the extra width provided by the anamorphic process. Designed for MFT/APS-C cameras with an MFT mount, the lens increases the horizontal FOV by 33% compared with traditional 24mm APS-C lenses. After de-squeezing, the captured image is displayed in a 2.4:1 format in a 16:9 setting. Lightweight and portable, the f/2.8 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. 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) 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.
