The world of cinematography is filled with various camera mounts, each with its unique characteristics, advantages, and disadvantages. Two of the most popular mounts in the industry are the PL (Positive Lock) mount and the EF (Electro Focus) mount. In this article, we will delve into the details of both mounts, exploring their history, design, compatibility, and performance. By the end of this article, you will have a clear understanding of which mount is better suited for your cinematography needs.
A Brief History of PL and EF Mounts
The PL mount was introduced in the 1980s by Arri, a renowned German camera manufacturer. It was designed to provide a secure and reliable connection between the camera and lens, making it an ideal choice for film and television production. The PL mount quickly gained popularity among cinematographers due to its durability and versatility.
On the other hand, the EF mount was introduced by Canon in the late 1980s. It was designed for Canon’s EOS (Electro-Optical System) cameras and was initially used for still photography. However, with the advent of digital cinema, the EF mount became a popular choice for cinematographers due to its compatibility with Canon’s C-series cameras.
Design and Construction
The PL mount is designed with a flange focal distance of 52mm, which provides a secure and stable connection between the camera and lens. The mount is typically made of metal and features a positive locking mechanism, ensuring that the lens is securely attached to the camera.
In contrast, the EF mount has a flange focal distance of 44mm and is designed with a bayonet-style locking mechanism. The EF mount is also typically made of metal, but it is often lighter and more compact than the PL mount.
Mounting System
The PL mount features a four-point mounting system, which provides a secure and stable connection between the camera and lens. The mounting system consists of four screws that are evenly spaced around the mount, ensuring that the lens is properly aligned and secured.
The EF mount, on the other hand, features a bayonet-style mounting system. The mount has a series of tabs and slots that align with the lens, providing a secure and quick connection.
Compatibility
The PL mount is widely compatible with a range of cameras and lenses from various manufacturers, including Arri, Red, and Zeiss. The mount is also compatible with a range of adapters, allowing cinematographers to use lenses from other manufacturers.
The EF mount, on the other hand, is primarily compatible with Canon cameras and lenses. However, there are a range of adapters available that allow cinematographers to use EF mount lenses on other cameras, including those from Arri and Red.
Camera Compatibility
The PL mount is compatible with a range of cameras, including:
- Arri Alexa
- Arri Amira
- Red Epic
- Red Scarlet
- Zeiss Supreme
The EF mount is primarily compatible with Canon cameras, including:
- Canon C300

- Canon C700
Performance
The PL mount is known for its durability and reliability, making it an ideal choice for film and television production. The mount is designed to withstand the rigors of heavy use and provides a secure connection between the camera and lens.
The EF mount, on the other hand, is known for its speed and convenience. The bayonet-style locking mechanism provides a quick and easy connection between the camera and lens, making it an ideal choice for fast-paced productions.
Optical Quality
The PL mount is designed to provide optimal optical quality, with a flange focal distance of 52mm that ensures a precise and stable connection between the camera and lens. The mount is also designed to minimize lens breathing and distortion, providing a high-quality image.
The EF mount also provides high-quality optics, with a flange focal distance of 44mm that ensures a precise connection between the camera and lens. However, some cinematographers have reported issues with breathing and distortion when using EF mount lenses.
Conclusion
In conclusion, both the PL mount and EF mount have their advantages and disadvantages. The PL mount is known for its durability and reliability, making it an ideal choice for film and television production. The EF mount, on the other hand, is known for its speed and convenience, making it an ideal choice for fast-paced productions.
Ultimately, the choice between the PL mount and EF mount will depend on your specific cinematography needs. If you are working on a film or television production that requires a high level of durability and reliability, the PL mount may be the better choice. However, if you are working on a fast-paced production that requires speed and convenience, the EF mount may be the better choice.

What is the main difference between PL Mount and EF Mount?
The primary difference between PL Mount and EF Mount lies in their design and functionality. The PL Mount, also known as the Positive Lock Mount, is a type of lens mount that uses a positive locking mechanism to secure the lens to the camera body. This design provides a more robust and reliable connection, making it ideal for heavy-duty cinematography applications. On the other hand, the EF Mount, also known as the Electro Focus Mount, is a type of lens mount that uses a bayonet-style locking mechanism and is primarily designed for still photography and some cinematography applications.
In terms of compatibility, PL Mount lenses are typically designed for use with cinema cameras, while EF Mount lenses are designed for use with still cameras and some cinema cameras. However, many modern cinema cameras offer adapters that allow the use of EF Mount lenses, making them more versatile. Ultimately, the choice between PL Mount and EF Mount depends on the specific needs and preferences of the cinematographer.
Which mount type is more widely used in the film industry?
The PL Mount is more widely used in the film industry due to its robust design and reliability. Many high-end cinema cameras, such as those from Arri and Red, use the PL Mount as their primary lens mount. This is because the PL Mount is designed to withstand the rigors of heavy-duty cinematography, including high-speed shooting and extreme temperatures. Additionally, many professional cinematographers prefer the PL Mount due to its ability to provide a secure and stable connection between the lens and camera body.
In contrast, the EF Mount is more commonly used in still photography and some lower-end cinematography applications. However, many cinematographers also use EF Mount lenses, especially when working with smaller camera systems or on lower-budget productions. Ultimately, the choice of mount type depends on the specific needs and preferences of the cinematographer, as well as the type of project being worked on.
Can I use EF Mount lenses on a PL Mount camera?
Yes, it is possible to use EF Mount lenses on a PL Mount camera using an adapter. Many camera manufacturers offer adapters that allow EF Mount lenses to be used on PL Mount cameras. These adapters typically provide a secure and stable connection between the lens and camera body, allowing for smooth and accurate focus control. However, it’s essential to note that using an adapter may affect the overall performance and image quality of the lens.
When using an EF Mount lens on a PL Mount camera, it’s crucial to ensure that the adapter is of high quality and designed specifically for the camera and lens being used. Additionally, some EF Mount lenses may not be compatible with certain PL Mount cameras, so it’s essential to check compatibility before purchasing an adapter. In general, using an adapter can be a convenient and cost-effective way to expand the range of lenses available for use on a PL Mount camera.
Are PL Mount lenses more expensive than EF Mount lenses?
