Product Overview
The DZOFilm Thypoch Positive Lock M Mount for ARRI Cameras adapts compatible Leica M-mount lenses for supported ARRI PL-mount cinema cameras. Its positive-lock mechanism is designed to resist unwanted lens movement during manual focusing or motor-driven focus pulls, while a secondary safety lock helps prevent accidental release. A repositionable, detachable handle and durable stainless steel body make this mechanical lens adapter practical for carefully configured cinema camera rigs. Confirm camera-model and rear-lens clearance before installation.
The Thypoch Positive Lock M Mount for ARRI Cameras is a mechanical Leica M-to-ARRI PL lens mount adapter supplied under manufacturer model TP-MPLAARRI and Coremicro SKU DZO-TP-MPLAARRI. Its manufacturer-specified body material is SUS 304 stainless steel, and its weight is approximately 190g (6.7 oz). The design includes a positive locking mechanism, secondary safety retention, and a detachable handle that can be repositioned or replaced with a flat nonslip module. It does not provide electronic lens communication. Thypoch identifies ARRI ALEXA 35, ALEXA Mini LF, ALEXA 265, and ALEXA 65 as compatible without camera modification; compatibility with other bodies and individual Leica M lenses must be checked. Back-focus calibration may require the supplied shim set and proper installation procedures.
Leica M Lens to ARRI PL Camera Mount
Bring compatible Leica M-mount lenses into an ARRI cinema-camera workflow through a purpose-built PL-side mechanical interface. This adapter does not change a lens's optical properties or provide electronic conversion. Check both the camera's mount configuration and the rear profile of the specific lens before fitting it.
Positive-Lock Retention for Stable Focus Operation
The positive-lock design holds the M-mount lens firmly to help reduce mount play and small movements during focus adjustments. This is useful when operating a manual focus ring or compatible follow-focus motor. It supports repeatable camera-department setup without claiming that every lens fit is identical.
Secondary Safety Lock Against Accidental Release
A secondary locking safeguard complements the main positive-lock mechanism. It is designed to reduce the chance of unintentional lens disengagement while a camera is handled or repositioned. Operators should still confirm positive engagement and use appropriate lens support before shooting.
Detachable and Repositionable Locking Handle
The locking handle can be repositioned to suit camera-button placement and the operator's preferred grip. A flat nonslip alternative is also supported when a protruding handle is undesirable. Confirm the hardware and handle components supplied with this exact Coremicro SKU before ordering.
SUS 304 Stainless Steel Adapter Body
The M-ARRI version uses a stainless steel body rather than the lighter aluminum-alloy construction found on some mirrorless Thypoch adapters. Its approximately 190g weight reflects this cinema-oriented construction. Plan for the complete camera, adapter, and lens weight when balancing a rig.
Shim-Adjustable Flange Alignment for Cinema Use
Back-focus alignment is important when adapting Leica M optics to an ARRI cinema body. Thypoch provides guidance for shim-based calibration of the M-ARRI adapter; the procedure includes checking infinity focus. Installation and adjustments should follow the manufacturer's instructions or be handled by qualified camera service personnel.
Thypoch identifies ARRI ALEXA 35, ALEXA Mini LF, ALEXA 265, and ALEXA 65 as compatible with its M-ARRI positive-lock mount without modifying the camera body. For ARRI AMIRA and older ALEXA Mini models, manufacturer guidance notes that hardware modification may be required, particularly when pairing with Thypoch Simera or Simera-C lenses. Compatibility can also depend on the exact Leica M lens's rear flange shape, sensor clearance, and correct flange calibration. Check current Thypoch and ARRI guidance for the complete camera-and-lens combination before use.
Use Selected M-Mount Optics on ARRI Camera Rigs
Adapt compatible compact M-mount lenses for an ARRI PL-camera workflow while checking rear clearance, coverage, and the selected camera's mount configuration.
Reduce Unwanted Lens Play During Focus Changes
Positive-lock retention helps keep the lens mechanically seated when an assistant adjusts focus by hand or with compatible external equipment.
Configure Handle Position and Calibrate Back Focus
Arrange the detachable handle around nearby camera controls and verify shim setup, infinity focus, and lens clearance before production.

What does the Thypoch Positive Lock M Mount for ARRI do?
It is a mechanical adapter that allows compatible Leica M-mount lenses to be fitted to supported ARRI PL-mount cinema camera systems. It uses positive-lock retention to help reduce unwanted movement at the lens connection.
Which ARRI cameras are compatible with TP-MPLAARRI?
Thypoch lists ALEXA 35, ALEXA Mini LF, ALEXA 265, and ALEXA 65 as compatible without camera modification. ARRI AMIRA and older ALEXA Mini cameras may require service-center modifications with certain lenses. Confirm the exact camera, lens, and rear clearance before use.
Can this adapter mount any Leica M lens on an ARRI camera?
The adapter is designed for a broad range of Leica M-mount lenses, but fit is not universal. Rear-lens protrusion, camera clearance, optical coverage, mount configuration, and flange calibration must be checked for each combination.
How does the positive-lock and safety-lock system work?
The main positive-lock mechanism clamps the M-mount lens to reduce small movements during operation. A secondary safety lock provides additional protection against accidental release. Always verify that both are correctly engaged before handling the camera.
Does installing the M-ARRI adapter require camera modification?
The ALEXA 35, ALEXA Mini LF, ALEXA 265, and ALEXA 65 are listed by Thypoch as compatible without modification. Older ALEXA Mini and AMIRA cameras can have additional requirements, particularly with Simera lenses. The adapter may also require shim adjustment to achieve correct back focus.
Can the Thypoch locking handle be moved or removed?
Yes. Its handle module is detachable and can be repositioned to avoid nearby camera controls. The design also accommodates a flat nonslip replacement module. Confirm the supplied handle accessories for this exact product configuration.
Does the Thypoch M-ARRI adapter transmit electronic lens data?
No. TP-MPLAARRI is a mechanical adapter without electronic communication. It does not provide autofocus, electronic aperture control, or lens metadata transmission by itself.
