1、 Definition of PL lens mount

Definition of PL lens mount:

PL lens mount is a standard lens mount used in the film and video industry. It is a type of bayonet mount that allows for quick and easy attachment and detachment of lenses from the camera body. The PL mount was first introduced by ARRI in the 1970s and has since become the industry standard for professional cinema cameras.

The PL mount is designed to accommodate a wide range of lenses, including prime lenses, zoom lenses, anamorphic lenses, and specialty lenses. It has a flange focal distance of 52mm, which means that the distance between the lens mount and the film or sensor plane is fixed at 52mm. This allows for precise focusing and accurate depth of field control.

One of the advantages of the PL mount is its versatility. It can be used with a variety of camera systems, including ARRI, RED, Sony, and Canon. This makes it a popular choice among filmmakers who need to switch between different camera systems on a regular basis.

In recent years, there has been a growing trend towards using PL mount lenses on digital cinema cameras. This is because PL mount lenses are designed to cover the larger sensor sizes used in modern digital cinema cameras, such as the ARRI Alexa and RED Dragon. This allows filmmakers to achieve a cinematic look with digital cameras, which was previously only possible with film cameras.

PL lens mount is a standard lens mount used in the film and video industry. It stands for Positive Locking mount and is also known as Arri PL mount. It was developed by Arri in the 1970s and has since become the industry standard for professional cinema cameras. The PL mount is a bayonet-style mount that allows for quick and secure attachment of lenses to the camera body. It has a flange focal distance of 52mm, which means that lenses with a longer flange focal distance can be adapted to fit the mount.

Disadvantages of PL lens mount:

One of the main disadvantages of the PL lens mount is that it is not compatible with other lens mounts. This means that if you have a camera with a PL mount, you can only use lenses that are designed for that mount. This can be limiting if you want to use lenses from other manufacturers or if you want to switch to a different camera system.

Another disadvantage of the PL lens mount is that it is primarily designed for use with large, heavy cinema lenses. This can make it difficult to use with smaller, lighter lenses, which may not be well-balanced on the camera body. Additionally, the PL mount is not designed for autofocus or electronic communication between the lens and camera, which can be a disadvantage for some users.

However, it is worth noting that the PL lens mount is still widely used in the film and video industry due to its robustness and reliability. It is also compatible with a wide range of high-quality cinema lenses, which can produce stunning image quality. Additionally, many modern cinema cameras now offer electronic communication with PL mount lenses, which can provide additional functionality and control.
