Continuing with the series of articles “Photographic or cinematic lens and its characteristics”, where we talk about the focal length and what is the main objective in this article, I will explain the different montages of photographic and cinematic lenses.
Mounting a photographic or cinematographic lens is a mechanical and electrical interface between the camera housing and the lens. The frame is a unique feature of cameras that allow the exchange of interchangeable lenses. It is limited to cameras whose body allows interchangeable lenses, usually The camera models are: rangefinder, SLR (single lens reflex) today DSLR or HDSLR and cameras of 16 mm, 35 mm, etc. The lens mount also exists to connect optical components to instruments that may or may not involve a camera, examples: microscopes and telescopes.
- Can the assembly of a photographic or cinematic lens be of the type?Threading? Or bayonet.
- Currently.
- The bayonet type is the most widely used.
- Due to the precision of the mechanical and electrical alignment between the lens and the camera housing and its secure locking system.
Bayonet mounts have several lashes, usually three around the base of the lens, with a manufacturer-determined size that fits the front nozzle of the digital camera. Eyelashes are often entered, and what does that mean?Lens to the camera housing by a precise system, with a single orientation, also has a locking system, which ensures this setting, once the lens is inserted, fixed by turning a little, then locked by a pin connected to a button that has a spring in the cameras or by a locking ring on the video cameras where these systems are used to lock or remove the lens.
Each manufacturer (Sony, Nikon, Canon, Contax/Yashica, Pentax, etc. ) has its mounting model (bayonet), which are almost always incompatible, in addition to mechanical and electrical variations, many argue that these inconsistencies are due to the willingness of manufacturers to “keep” (keep in Portuguese clear) consumers with their brand.
In cinema chambers, the most commonly used luminaires currently in the professional segment are: the set created by ARRIFLEX, the PL (“Positive Lock”), and the Panavision set, the photovoltaic set. PL media is used in both ARRI cameras and various models of digital cinema cameras, such as RED, BlackMagic, Canon, Sony, Panasonic, etc. Panvision mounts are used exclusively with Panavision lenses and cameras, and are only available for rent at a Panavision rental company, while the PL mount is offered by a wide variety of camera and film lens manufacturers. The two games, Panavision and ARRI, are joined with pins and locking rings.
