Moment Anamorphic adapter VS Sirui Anamorphic adapter

Are you a filmmaker or photographer looking to elevate your visual storytelling by adding an anamorphic touch to your shots? The Moment Anamorphic adapter and the Sirui Anamorphic adapter are two popular options that can help you achieve that desired cinematic look. Both adapters offer unique features and capabilities that can enhance your creative vision, but choosing the right one can be a daunting task. In this blog, we will compare the Moment Anamorphic adapter versus the Sirui Anamorphic adapter, highlighting their key differences and helping you make an informed decision. So, let’s dive in and discover which adapter will be the perfect fit for your artistic needs.

Moment Anamorphic Adapter vs. Sirui Anamorphic Adapter: A Comprehensive Comparison


When it comes to anamorphic adapters, two popular options in the market are the Moment Anamorphic Adapter and the Sirui Anamorphic Adapter. In this article, we will dive into the features, pros, and cons of these adapters to help you determine if they are worth your investment. We will also discuss the versatility of owning such adapters and provide insights on their image quality. Let’s get started!

Versatility and Flexibility

One of the major advantages of owning an anamorphic adapter, like the Moment or Sirui, is the ability to transform any lens into an anamorphic lens. By simply screwing the adapter onto the front of your lens, you can achieve the unique anamorphic look without having to invest in a dedicated anamorphic lens. This offers users greater flexibility and versatility in their shooting setups.

Compatibility and Limitations

However, it’s important to consider the limitations of these adapters. The Moment Anamorphic Adapter can only be used with lenses that are 50mm and above in focal length for full frame cameras (or their equivalent for APS-C cameras). Trying to use it with wider angle lenses may result in significant vignetting, as the image circle is not large enough to cover these lenses adequately. On the other hand, the Sirui Anamorphic Adapter offers similar limitations in terms of focal length compatibility.

Packaging and Accessories

Both the Moment and Sirui adapters come in well-packaged cases, providing protection and convenience. The Moment Anamorphic Adapter package includes three step-down rings (72mm, 77mm, and 82mm), allowing you to adapt it to lenses with different front filter thread sizes. This versatility is highly appreciated and simplifies the workflow for photographers and filmmakers. It’s worth noting that keeping the adapter as close as possible to the lens element is recommended for optimal results.

Usage and Image Quality

To achieve the anamorphic effect, you need to set your lens to infinity focus after attaching the adapter and then focus directly with the anamorphic adapter itself. Both the Moment and Sirui adapters feature a button that allows you to rotate the orientation of the adapter, aligning the flares horizontally and ensuring straight and vertical lines. This feature is essential in creating visually appealing shots.

When it comes to image quality, sharpness can be a drawback of using anamorphic adapters. This is not exclusive to either the Moment or Sirui adapters; it’s a common issue with most adapters. The adapters tend to reduce the overall sharpness of the lens, making it necessary to stop down the aperture to achieve acceptable focus. However, this may result in a loss of light. On the positive side, the adapters add character to the images by introducing barrel distortion and creating pleasing out-of-focus backgrounds.

It’s worth mentioning that the sharpness results may vary depending on the specific lens used. Some lenses may perform better than others with the adapters, so it’s essential to test and find the most compatible lens for your needs.


After evaluating the Moment Anamorphic Adapter and the Sirui Anamorphic Adapter, it’s clear that both have their strengths and limitations. While the adapters provide greater flexibility and the ability to achieve anamorphic characteristics with any lens, they may sacrifice some sharpness in the process. However, this trade-off can be acceptable for filmmakers and photographers who prioritize the unique character and aesthetic appeal of anamorphic footage.

Ultimately, the decision between these two adapters depends on your specific needs and preferences. Consider factors such as the focal length compatibility, image quality, and the desired look for your footage. By understanding the capabilities and limitations of these adapters, you can make an informed choice and determine if they are worth the investment.
