The two main versions of the sirui 35mm anamorphic lens have different matching needs based on their specs. The recommended accessories and filters below are tailored to their respective characteristics, covering image enhancement, functional expansion, and shooting stability. Here are the details:
Filters
The Sirui 35mm f/1.8 1.33x usually has a 67mm filter thread, while the Saturn 35mm 1.6x full-frame version has a 58mm or 82mm thread. The following filters are widely used and compatible:
Neutral Density (ND) Filters: These are essential for video shooting with the Sirui 35mm f/1.8 1.33x. Its f/1.8 large aperture easily leads to overexposure in bright environments, especially when shooting with a low frame rate and wide aperture to create shallow depth of field. The Cokin Nuances Variable ND Filter (67mm) is a great fit. It comes in 1 - 8 stop and 5 - 10 stop options, featuring Schott B270 glass and 16 - layer multi - coating to reduce light input without distorting colors. For the full - frame 1.6x version, you can choose ND filters matching its 58mm or 82mm thread to maintain proper exposure during outdoor dynamic shooting like drone aerial photography.
Black Mist/Diffusion Filters: Ideal for portrait and mood - oriented shooting. The 7Artisans 67mm 1/8 Black Mist Filter works well with the 35mm f/1.8 1.33x. It softens harsh highlights, lowers contrast, and smooths skin tones in portrait shots, making the picture more cinematic instead of rigid. Similarly, Hoya Diffuser No.1 Filter (67mm) can reduce the harshness of highlights, which is perfect for shooting travel vlogs and documentaries to get a warmer and more natural visual effect.
Streak Filters: To enhance the anamorphic lens' light - streak effect. The 7Artisans 67mm Blue Streak Filter can complement the 35mm f/1.8 1.33x's inherent blue light streaks. When shooting against the light, it strengthens the sci - fi or dreamy atmosphere of the picture. The orange version of this filter can also add warm - toned light streaks, bringing more color variations to scenes such as sunset portraits and night street views.
Accessories
Anamorphic Adapters: A must - have for the Saturn 35mm 1.6x full - frame version. The lens is available in kits with a 1.25x anamorphic adapter. When used together with the 1.6x lens, it can achieve a 2x squeeze ratio, further enhancing the wide - angle effect and cinematic sense of the picture. Additionally, this adapter can be mounted on spherical lenses to get a 1.25x squeeze effect, improving its versatility.
Lens Mount Adapters: The 35mm f/1.8 1.33x lacks a full range of mount options. Sirui offers dedicated adapters for E - mount, EF - M mount, and Z - mount. These aluminum adapters allow the lens to switch between different brand cameras easily. For example, the Nikon Z - mount adapter enables the lens to be used on Nikon Z - series cameras, which is convenient for creators who use multiple camera systems.
Step - up/Step - down Rings: Necessary for filter and matte box compatibility. The Saturn 35mm 1.6x has a 58mm filter thread, which is small. When using matte boxes like the Tilted Mirage, you need step - up rings to fit the filter rings of the matte box. The 35mm anamorphic lens series also offers 67mm, 72mm, 77mm step - down rings and a 92mm step - up ring, allowing it to match various universal filters and accessories on the market.
Focusing and Stabilization Accessories: The sirui 35mm anamorphic lenses are manual - focus. A follow - focus system can improve focusing accuracy during video shooting, especially for scenes requiring continuous focus like moving portraits. In terms of stabilization, since both lenses are lightweight, they can be paired with gimbals such as DJI RS 3 Mini. This is particularly important for the full - frame version used on drones, as it ensures the stability of the picture during dynamic shooting.
Matte Boxes: Suitable for outdoor shooting with strong light. Although the 58mm thread of the Saturn 35mm 1.6x makes it a bit tricky to match matte boxes, after using step - up rings, you can install small - sized matte boxes like those from SmallRig. They block stray light to avoid lens flare, ensuring the clarity and contrast of the picture when shooting landscapes and architecture in strong sunlight.
