HEXAMO: A Mechanical Shortcut to Premium Vintage Glass on ARRI ALEXA
The HEXAMO mount adapter is a dedicated mechanical conversion system from P+S Technik that allows Leitz HEKTOR Cine Prime lenses, originally built for short-flange mirrorless cameras, to reach full infinity focus on ARRI ALEXA bodies without changing the camera platform or compromising the internal filter system. P+S Technik has introduced HEXAMO as a new ARRI ALEXA lens mount solution specifically designed for Leitz HEKTOR cine primes, overcoming a compatibility gap that made these lenses unusable on ALEXA until now. This is not another generic adapter ring; it is a rethinking of the physical interface between camera and lens so that cinematographers can combine an ARRI ALEXA sensor with the organic, flare-heavy HEKTOR image character that has been limited to mirrorless workflows. In practical terms, HEXAMO turns the ALEXA into a far more flexible vintage glass platform without asking productions to abandon a trusted camera ecosystem.
Why This Matters: Preserving the ARRI ALEXA Workflow While Expanding Lens Choice
P+S Technik’s move is important because it respects how films are actually made. The ARRI ALEXA platform is already deeply embedded in production pipelines, from rental houses to post workflows; asking teams to switch to mirrorless bodies just to access Leitz HEKTOR cine primes was a non-starter. Until now, those primes were engineered only for modern mirrorless systems, whose short flange focal distances made them physically incompatible with the standard ARRI ALEXA lens mount. Conventional adapters pushed the glass too far from the sensor, killing infinity focus and making the setup unusable on set. With HEXAMO, cinematographers gain cinema lens compatibility between HEKTOR glass and the ALEXA ecosystem, pairing the camera’s well-known reliability with the HEKTOR signature—smooth focus roll-off, organic rendering, and distinctive flares. The real takeaway: you no longer have to trade your camera body for a different look.
How HEXAMO Changes the ARRI ALEXA Lens Mount Game
The HEXAMO solution is opinionated: instead of stacking adapters, it replaces the ARRI ALEXA lens mount with a low-profile block and reworks the rear of each HEKTOR lens. The original ALEXA mount block can be removed by loosening four screws, then swapped for P+S Technik’s specially developed low-profile mount that recreates the short flange depth HEKTOR lenses expect. On the lens side, each Leitz HEKTOR cine prime receives a precision-machined, three-part rear interface assembly that becomes the dedicated counterpart to the HEXAMO camera mount, followed by careful calibration for accurate flange depth and consistent optical performance. The combination of these two conversions allows HEKTOR primes to achieve full infinity focus on ARRI ALEXA bodies while preserving compatibility with the camera’s internal filter system. A red locking ring then secures the lens with a rigid, play-free connection able to withstand modern wireless FIZ torque.
Creative Impact: Hexamo as a Bridge Between Legacy Optics and Modern Production
The real value of HEXAMO is not technical; it is creative. Cinematographers have been chasing specific optical signatures—soft roll-off, organic micro-contrast, and expressive flares—that digital perfection often flattens. The Leitz HEKTOR series sits squarely in that premium vintage aesthetic, but its mirrorless-only design kept it at arm’s length from ALEXA-based shows. With HEXAMO, P+S Technik offers a mechanical bridge that pairs mirrorless-designed HEKTOR lenses with the ARRI mount ecosystem, opening new combinations of texture and dynamic range without forcing productions off their established cameras. According to P+S Technik, “HEXAMO opens the door to a unique combination of the HEKTOR image signature and the reliability of the ARRI Alexa – something that was previously not possible.” For rental houses, this is a practical way to add distinctive glass without retiring existing ALEXA inventories; for filmmakers, it is another lever to shape mood, nostalgia, or imperfection in-camera rather than in post.
Who Should Care: ALEXA Owners, Vintage-Lens Lovers, and Productions Seeking a Distinct Look
HEXAMO is not aimed at casual shooters; it targets people whose decisions ripple through entire productions. Cinematographers and productions already invested in ARRI ALEXA cameras gain direct access to Leitz HEKTOR cine primes’ visual character without moving to mirrorless bodies or juggling separate rigs. Rental houses can now offer an ARRI ALEXA lens mount option that stands out from the standard modern glass lineup, giving clients a clear creative differentiator on the shelf. Crucially, this solution addresses a specific cinema lens compatibility problem: HEKTOR primes were designed around short flange distances, which previously made infinity focus unattainable on ALEXA with conventional adapters. By solving that mechanical mismatch, HEXAMO turns what used to be a strict either-or choice—ALEXA reliability or HEKTOR character—into a both-and proposition. For anyone chasing a recognisable, organic look on a familiar camera, that is a meaningful upgrade.
