How to Turn Any Lens into Anamorphic One

Anamorphic adapters are optical accessories that can be attached to a regular camera lens to create an anamorphic effect, which produces a wider aspect ratio than the standard 4:3 or 16:9. As anamorphic lenses are used to create a cinematic look by compressing the image horizontally before it is recorded on the camera’s sensor, and then expanding it back to its original width during post-production.

Why use anamorphic adapters

Anamorphic adapters are commonly used in cinematography to achieve a wider aspect ratio, typically a 2.39:1 aspect ratio, which is wider than the standard 16:9 aspect ratio. This wider aspect ratio provides a more cinematic and immersive look to the footage.

Anamorphic adapters can also provide a unique and aesthetically pleasing look to footage, with distinctive lens flares, oval-shaped bokeh, and a more shallow depth of field.

They can also be used in still photography, particularly in portrait and landscape photography where a wider aspect ratio and unique lens characteristics can enhance the visual impact of the image.

The pros & cons of using anamorphic adapters

Using an anamorphic adapter has both pros and cons compared to using an actual anamorphic lens. Here are some of the main advantages and disadvantages:


  • Cost: Anamorphic adapters are generally much less expensive than actual anamorphic lenses, making them a more accessible option for filmmakers on a budget.
  • Flexibility: Anamorphic adapters can be attached to a wider variety of lenses than actual anamorphic lenses, allowing filmmakers to achieve an anamorphic look with lenses they already own.
  • Portability: Anamorphic adapters are generally smaller and lighter than actual anamorphic lenses, making them a more portable option for run-and-gun shooting.
  • Compatibility: Anamorphic adapters can be used with a wider range of cameras and sensors than actual anamorphic lenses, which are often limited to specific mounts and sensor sizes.


  • Optical Quality: While some anamorphic adapters offer high-quality optics, it can be difficult to achieve the same level of optical performance as an actual anamorphic lens. Adapters may introduce optical artifacts such as distortion, chromatic aberration, and flares.
  • Setup Time: Using an anamorphic adapter requires attaching the adapter to a lens and aligning it properly, which can be time-consuming and may require additional gear such as a follow focus and matte box.
  • Focus and Iris Control: Depending on the adapter and lens combination, controlling focus and iris can be more difficult than with a dedicated anamorphic lens, as adapters may not transmit lens data to the camera or require separate focus and iris controls.
  • Limited Options: While there are many different anamorphic adapters available, the selection is still more limited than that of actual anamorphic lenses. Some anamorphic adapters may only be compatible with certain lenses or cameras, limiting their flexibility.

Ultimately, the decision to use an anamorphic adapter or an actual anamorphic lens will depend on the specific needs and budget of the filmmaker, as well as the desired level of optical performance and ease of use.

Anamorphic adapter types:

Anamorphic adapters are used in cinematography to achieve a wider aspect ratio by horizontally squeezing the image onto the camera’s sensor or film stock, which is then unsqueezed in post-production. There are different types of anamorphic adapters, including:

  1. Clamp-on anamorphic adapter: These adapters are designed to be clamped onto the front of a prime or zoom lens, allowing you to quickly attach and detach them from your setup.
  2. Bayonet mount anamorphic adapter: These adapters feature a bayonet mount that allows them to attach directly to the camera body, eliminating the need for an additional lens mount.
  3. Rear-mounted anamorphic adapter: These adapters are mounted on the rear of a lens, allowing you to use them with a wider variety of lenses.
  4. Front-mounted anamorphic adapter: These adapters are mounted on the front of a lens, typically with a screw-on or bayonet mount, and are used for achieving a wider field of view.

Common specifications of an anamorphic adapter

Anamorphic adapters can have a variety of specifications that affect their performance and compatibility with different lenses and cameras. Here are some common specifications you might see:

  • Squeeze Factor: This refers to the amount of horizontal compression applied by the anamorphic adapter. For example, a 1.33x anamorphic adapter will stretch the image horizontally by a factor of 1.33, resulting in a wider field of view and a distinctive oval-shaped bokeh.
  • Front Filter Thread Size: This refers to the size of the front filter thread on the anamorphic adapter. This is important because it determines which filters or step-up rings you can use with the adapter.
  • Lens Compatibility: This refers to the types of lenses that the anamorphic adapter is designed to work with. Some adapters may be designed for use with cinema lenses, while others may be compatible with stills lenses or both.
  • Minimum Focus Distance: This refers to the closest distance at which the anamorphic adapter can focus. This is important if you plan to shoot close-up or macro footage.

How to choose an anamorphic adapter

When selecting an anamorphic adapter, there are several factors to consider, including:

  1. Compatibility: Anamorphic adapters may be designed for use with specific lens mounts or sensor sizes, so it’s important to ensure that the adapter you choose is compatible with your camera and lens.
  2. Squeeze Factor: The squeeze factor determines how much the image is horizontally compressed by the anamorphic adapter. Common squeeze factors include 1.33x, 1.5x, and 2x. A higher squeeze factor will result in a more pronounced anamorphic look, but it may also introduce more distortion and require a wider aspect ratio for playback.
  3. Image Quality: Anamorphic adapters can introduce some optical artifacts, but a good adapter should minimize these effects and deliver high-quality images. Look for adapters with high-quality optics, anti-reflective coatings, and other features that enhance image quality.
  4. Build Quality: Anamorphic adapters are precision optical instruments, so it’s important to choose one that is well-built and durable. Look for adapters made from high-quality materials and with robust construction.
  5. Focal Length: The focal length of your lens can affect the performance of an anamorphic adapter. Longer lenses (50mm or above) tend to work best with anamorphic adapters, as they minimize distortion and produce a more cinematic look. However, adapters may be available for shorter lenses as well.
  6. Minimum Focus Distance: The minimum focus distance is the closest distance at which the anamorphic adapter can focus. This is important if you plan to shoot close-up or macro footage.
  7. Price: Anamorphic adapters can range in price from a few hundred dollars to several thousand dollars, so it’s important to consider your budget when selecting an adapter. Keep in mind that a more expensive adapter may offer better image quality and durability, but it may not be necessary for all types of filmmaking.

Finally, by considering these factors and doing research on different anamorphic adapters, you can select the best one for your needs and achieve the unique anamorphic look you desire.

Low-budget anamorphic adapters

There are several anamorphic adapters available in the market that can be attached to a standard camera lens. Generally speaking, their prices increase with the increase of the squeeze factor of the adapter. The following are some good options of low budget anamorphic adapters:
