SIRUI lenses are available in multiple mounts, including Sony E, Canon RF, Nikon Z, Fujifilm X, Leica L, MFT, EF, and PL mount options. Always verify both the lens mount and sensor format compatibility before purchasing.

The 24mm lens is a lens with a focal length of 24mm (millimeters). Focal length is the length from the optical center of the lens to the camera’s sensor. It is great for landscape, street, and architecture photography, and also works well for food and blue hour shots. It might even be the best lens for indoor photography. It does a beautiful job on most hotel rooms, bathrooms, and when photographing food in restaurants. The wide f/stop makes it a great option in low light situations. It’s also a great lens for outdoor photography. It does well with landscapes and has minimal distortion that you see with other lenses.

A 35mm lens is a lens with a focal length of 35mm (millimeters). Focal length is the length from the optical center of the lens to the camera’s sensor. It is a great all-purpose lens. Its perspective is close to that of the human eye, making it an excellent choice for street and documentary work.
A 35mm lens is also a good choice as a first lens for aspiring photographers who want to learn how to zoom with their feet and how to frame scenes without relying on the camera’s LCD screen or electronic viewfinder (EVF). The original 35mm camera was a movie camera that used film stock that was 35mm wide. The format became very popular in both film and still photography because it offered a good compromise between compactness and image quality.

A 50mm lens is good for almost every type of photography.It has a fixed focal length of 50mm. It is the midpoint between a wide-angle lens and a telephoto lens. That means you are neither too close nor too far from the subject you want to capture. It gives you flexibility in your photography. A 50mm lens is a standard lens on a full-frame camera. It can capture an image close to what the human eye sees. It also usually has a wide maximum aperture for low-light shooting.

Lenses with focal lengths from 75mm to 150mm are all in the telephoto range, primarily used for subjects where the photographer needs distance, such as portraits, events, wildlife, and macro photography. They offer flattering perspectives by compressing the background and creating a shallow depth of field (bokeh).

A macro lens is a lens with large magnification that is specialized for close-up photography. These lenses can powerfully enlarge small subjects. Specifically, a macro lens has a short MOD (Minimum Object Distance) and a maximum magnification ratio of 0.5x to 1x (1:1 magnification). By using a macro lens, you can capture large views of fine details such as the veins of leaves and flowers, objects reflected in water droplets, insects, and other small objects. Types of macro lenses include wide-angle macro lenses with a short focal length, standard macro lenses with a moderate focal length, and telephoto macro lenses with a longer focal length.

Autofocus lenses are ideal for fast-paced photography, content creation, events, and run-and-gun filmmaking. Manual focus lenses offer greater precision and creative control, making them popular for cinematic productions and professional video work.

Yes. Many SIRUI lenses are designed for creators who work across both photography and video production. For example, the SIRUI Sniper Series autofocus lenses are ideal for portraits, street photography, travel content, and everyday video creation thanks to their fast autofocus performance and bright apertures. Filmmakers looking for a cinematic look often choose the SIRUI Saturn, Venus, IronStar, or Astra anamorphic lens series, which deliver widescreen imagery, oval bokeh, and signature lens flares. For professional video productions, SIRUI cine lenses provide precise manual focus control, consistent gear positioning, and smooth operation for follow-focus systems. Whether you're capturing still images, creating social media content, producing documentaries, or shooting narrative films, SIRUI offers lens options that can support both photography and video workflows.

•Lens cleaning
Step1: Prepare: Clean hands, dust-free space; detach lens if feasible.
Step2: Dust Removal: Use air blower or compressed air first, then a soft brush.
Step3: Wet Cleaning: Use lens cleaner on microfiber for tough spots; gentle circles.
Step4: Drying: Polish with a dry microfiber cloth till streak-free.
Step5: Tools Summary: Air blower, soft brush, lens solution, microfiber cloth, cleaning pens, cotton swabs for detail work.

•Moisture and dust proof
•Humidity Control: Store at 40-50% RH with dehumidifiers/silica gel.
•Airtight Cases: Use sealed, waterproof cases with padding for dust and humidity exclusion.
•Pre-Storage Cleaning: Thoroughly clean lenses to prevent dust accumulation.
•Desiccant Use: Integrate desiccant packs, replace regularly.
•Temperature Stability: Maintain cool temperatures, avoid heat and sunlight.
• Cap & Invert: Secure caps; invert for reduced dust on glass.
• Regular Checks: Inspect for moisture, mold regularly.
• Specialized Cabinets: Consider humidity-controlled camera cabinets for added protection.

• What is an anamorphic lens?
Commonly used in filmmaking to achieve a cinematic look, an anamorphic lens is a specialized lens that horizontally compresses the image during capture and then expands it during playback or post-processing. Anamorphic camera lenses allow for a wider field of view, creating a distinct widescreen aspect ratio and unique optical characteristics such as lens flares and stretched bokeh.

• How do anamorphic lenses work?
Anamorphic lenses utilize a cylindrical optical element to horizontally squeeze the image onto the camera's sensor or film frame. This compression alters the aspect ratio, resulting in a narrower, vertically stretched image. During playback or post-processing, the footage is de-squeezed to restore the original widescreen format. This process widens the field of view, providing a distinct cinematic aesthetic with enhanced horizontal resolution and unique optical characteristics such as lens flares and oval-shaped bokeh.

• What is the aspect ratio of anamorphic lenses?
The aspect ratio of anamorphic lenses typically depends on the specific format being used. In the realm of professional filmmaking, the most common anamorphic aspect ratios are 2.39:1 and 2.35:1. These ratios result from the horizontal compression and subsequent de-squeezing of the image during playback or post-processing. The wide aspect ratio achieved with anamorphic lenses allows filmmakers to create expansive, immersive visuals that are synonymous with the cinematic experience.

• Are there different types of anamorphic lenses?
Yes, there are different types of anamorphic lens. The most common anamorphic lenses are 1.33x, 1.6x, and 2x, and these refer to how much the lens squeezes the horizontal image onto the sensor. For instance, a lens with a 1.6x squeeze ratio will capture 1.6 x the width of the focal length. Our range includes both 1.33x and 1.6x anamorphic lenses as well as a 1.25X adapter allowing for up to 2x on the 1.6x lens range.

• What is the S35 frame?
The S35 frame, also known as Super 35mm, is a common image sensor size used in film cameras. Its dimensions are approximately 24.89 x 18.66mm. This format is primarily used in film and video production.

• What is the difference between S35 and Full Frame?
Full Frame sensors have dimensions of about 36 x 24mm, which is larger than S35 sensors. This means that Full Frame sensors can provide a larger field of view and better low-light performance. Additionally, Full Frame lenses typically require larger, more complex lens elements and optical designs, which can make them more expensive.

• What is the difference between S35 and APS-C?
APS-C sensors usually have dimensions ranging from 22.2 x 14.8mm (Canon) to 23.6 x 15.6mm (Nikon, Sony, etc.), which are smaller than S35 sensors. This means that S35 sensors can provide a larger field of view. Moreover, APS-C is the standard for most consumer and professional digital SLR (DSLR) and mirrorless cameras, while S35 is the standard in film and video production.

• Which frame should I choose?
This primarily depends on your shooting needs and budget. Full Frame provides the best image quality and the largest field of view, but it may be more expensive. S35 and APS-C might be more suitable for photographers with a limited budget but still want to achieve high-quality images.
