Simmod Lens has recently launched a new conversion system, specifically designed to adapt old Pentax Takumar lenses to modern cinema cameras. This system, made entirely of brass, is compatible with most M42 screw mount lenses, allowing them to fit onto the latest LPL cinema mount standard.
This new system is particularly advantageous for users of Pentax Takumar SMC M42 lenses. It includes the ProLock feature, which prevents the lens from unscrewing during operation. This feature is only compatible with original Pentax SMC Takumar lenses that have a locking pin, and it does not work with older Pentax Takumars or M42 lenses from other manufacturers.
Design and Stability
The design includes a submount with a locking tab that attaches to the pin on the Pentax lens. This part is then secured with screws to the LPL mount portion, ensuring a stable and secure connection between the lens and the camera body or the Simmod LPL lens adapter.
Installation Options
The installation of the Simmod M42-LPL conversion system can be carried out by individuals skilled in DIY lens modifications or by professional lens technicians. Simmod has a network of approved installers for this purpose. The system also comes with shims to ensure correct infinity focus. Like high-end cinema lenses, a lens with the Simmod M42-LPL conversion will need calibration for best performance.
Characteristics of Pentax Takumar Lenses
Pentax Takumar M42 lenses are known for their precise manual focus control, durable metal build, and compact size. However, when adapting these lenses to modern video cameras, users may face issues with the lens rotating during mounting. This is due to the design of the screw mount, which is less stable compared to bayonet mounts.
Benefits of the LPL Mount
The LPL mount, used in this conversion system, is suitable for larger sensors and has a wider diameter than the traditional PL mount. It is compatible with a range of cameras from ARRI, Sony, and RED.
Simmod’s Affordable LPL Adapters
Simmod Lens also offers a variety of LPL adapters at a lower price point compared to other options on the market. These adapters are available for various camera mounts and are made from durable brass and stainless steel.
Compatibility with Essence Magnetic Rear Diffusion Filters
The conversion system is also compatible with Simmod’s Essence Rear Magnetic filter system. This system allows for quick and easy changes of diffusion filters and is more compact and lighter than traditional filter systems. Simmod provides a range of Essence Rear Magnetic filters, including Aria Black Mist and Aria Glisten filters in various strengths.
