Sanyk 1.33x Anamorphic Lens for Mobile Phones: Cinematic 2.40:1 Widescreen Video Capture

Transform your smartphone into a pocket-sized cinema camera with the Sanyk 1.33x anamorphic widescreen lens. Designed to work with the vast majority of mobile phones, this accessory attaches via a simple 17mm thread and converts standard 16:9 video footage into the classic 2.40:1 cinematic aspect ratio favoured by filmmakers. Its core function is a precise 1.33x horizontal extrusion, which squeezes the image onto your phone's sensor, enabling you to desqueeze the footage in editing software for authentic, ultra-wide movies. With a distortion rating of under 2%, the lens maintains image integrity, and its compact, lightweight design ensures it adds minimal weight to your mobile videography kit.

Optical Design and Technical Specifications

The lens achieves its specific cinematic effect through a purpose-built optical formula. This section details the construction and measurable performance parameters that define its widescreen capabilities.

Anamorphic Magnification and Ratio

The lens provides a 1.33x horizontal magnification, which is the key to creating the elongated widescreen look. When shooting in your phone's standard 16:9 mode and applying this lens, the resulting footage can be processed to achieve a final 2.40:1 aspect ratio. This process replicates the look of professional anamorphic cinema lenses, adding a distinct visual character and a wider field of view to your videos without cropping in and losing resolution.

Lens Construction and Distortion

Housed within the aluminium barrel is an optical arrangement of 2 elements in 2 groups. This construction is engineered specifically for the anamorphic squeezing function. A key specification is its low distortion of under 2%, which helps preserve straight lines and natural proportions in your footage, ensuring the widescreen effect is achieved without significant unwanted image warping or aberrations that can detract from the professional result.

Focusing and Physical Dimensions

The lens has a stated minimum focusing distance ranging from 70mm to 90mm. This allows filmmakers to capture detailed close-up shots, adding versatility to storytelling. Physically, the lens is designed for portability with a maximum diameter of 30mm by 33mm and a total weight of just 35g. This keeps your mobile rig light and manageable for handheld shooting, vlogging, or travel filmmaking.

Compatibility and Mounting System

A major advantage of this lens is its broad compatibility, which removes the need for model-specific adapters in most cases. The mounting system is straightforward, designed for quick attachment to a wide range of devices.

Universal 17mm Thread Interface

The lens features a standard 17mm interface thread diameter. This is a common size used by many third-party smartphone camera cases and universal clip-on mounts. Users simply need to screw the lens directly onto a compatible case or adapter ring. This universal approach means the lens is not locked to a single phone brand or model, offering great flexibility and longevity as you upgrade your smartphone.

Wide Smartphone Compatibility

According to the provided specifications, this lens is compatible with more than 95% of mobile phones on the market. This high level of compatibility is due to the standardised 17mm thread and the lens's design, which does not rely on electronic communication with the phone. It works purely as an optical accessory, making it a versatile tool for a wide community of mobile videographers, regardless of their device.

Practical Setup and Use

Setting up involves screwing the lens onto your prepared smartphone mount. It is important to ensure the lens is securely attached and the front element is clean. When filming, remember that the viewfinder will show a squeezed image; the true 2.40:1 widescreen look is revealed during post-production desqueezing. This workflow is standard for anamorphic shooting and is easily managed with most common video editing software.

Benefits and Value for Mobile Creators

This lens offers a direct path to achieving a high-end cinematic aesthetic without the need for large, expensive camera systems. Its value lies in its specific function, practical design, and the creative control it grants to the user.

Achieving a Professional Cinematic Look

The primary benefit is the ability to capture video with the distinctive 2.40:1 widescreen aspect ratio, complete with the characteristic horizontal lens flares and oval bokeh often associated with anamorphic photography. This look is difficult to authentically replicate with digital cropping alone, as cropping reduces resolution and field of view. The anamorphic squeeze preserves the full sensor height, giving you a true cinematic frame.

Portability and Reusability

Weighing only 35g, the lens is an extremely portable addition to any filmmaker's kit. Its universal mounting system means it is not a disposable accessory tied to a single phone. As you change smartphones, you can likely continue using the same lens with a new compatible case, protecting your investment and maintaining a consistent look across your projects over time.

Why Choose This Anamorphic Lens

This lens stands out for its combination of a precise optical specification—1.33x magnification, under 2% distortion, 70-90mm close focus—and its practical, user-friendly design. The universal 17mm thread and high compatibility rate remove technical barriers to entry, making professional-style anamorphic videography accessible. It provides a concrete, measurable tool for enhancing mobile video production with a specific, sought-after visual style.
