DZOFILM Cinema Lens Repair
Laboratory authorized by the brand for the Repair, adjustment and parfocal calibration of DZOFILM lenses. We solve problems of back focus, We correct resolution problems and perform lens cleaning in an ISO 4 laminar flow chamber, addressing hardness in focus, zoom or iris gear rings.
Mechanical and optical failures at DZOFILM
Cinema lenses lack autofocus motors, relying entirely on optomechanical precision and extremely tight tolerances. As an authorized service center, we resolve lens wear, calibration loss, and metadata interference issues.
Loss of Back Focus
If your zoom lens loses focus when changing the focal distance, we perform a micrometric adjustment of the back focus using shims Original stainless steel calibrated in projector.
Resolution Projector and Collimator
In film, an off-center shot ruins the take. We have collimator and resolution projector (tools that are very uncommon in Spain) to certify that the glass performs mathematically perfect.
M 0.8 Gears and Stuck Rings
We restored smooth rotation and consistent torque to the diaphragm (T-stops), focus, and zoom rings. We repaired friction caused by impacts or loss of helical lubricant.
ISO 4 Laminar Flow Cabinet
We have ISO 4 laminar flow cabinet to intervene internally in the target. Here we eradicate fungi and perform the assembly in a particle-free, positive-pressure environment.
Reprogramming and Technology /i
We repaired the electronic contacts of the mount and intervened in the motherboards responsible for sending lens metadata (focus distance, iris) to the camera body.
Changing and Adjusting Frames
We replace damaged bayonets and perform precise conversions between interchangeable systems (PL, EF, L, E, RF) ensuring that the heavy anchor has no mechanical play.

DZOFILM lens park that we service in the workshop
We offer a service of guaranteed repair encompassing the brand's entire optical range geared towards the audiovisual sector. From the acclaimed Vespid Prime line to the complex parfocal structures of the Pictor and Catta Zoom.
Specialization in optomechanical engineering
DZOFILM optics are robust components whose performance is based on extremely high-tolerance mechanical calibration. We address clearances, ring hardening, calibrations, and metadata maintenance.
Our major advantages: We used a precision collimator, a resolution projector, and, crucial for opening these complex lenses, a ISO 4 laminar flow cabinet. These tools guarantee complete asepsis in the assembly and ensure that the shims return the exact focus without asymmetric vignetting or aberrations.
As an Official Center in Spain, we work exclusively with original factory spare parts (gears, pin plates, fine screws and sealed crystals).

Do you adjust the focus loss across the entire zoom range?
Yes, fixing parfocality loss is our specialty. Using millimeter-precision shim rings and testing them on our projector, we ensure that the back focus is correctly re-established on the sensor across the entire focal range.
What is the ISO 4 laminar flow cabinet needed for?
When removing glass of this caliber to clean it of spores (fungi), fog, or oils, it is essential that no speck of dust falls inside. ISO 4 positive pressure laminar flow cabinet It guarantees a sterile area, delivering a pure and professional seal.
How important is it to repair the lens with a collimator?
Without a collimator, a disassembled lens suffers from deviations. The laser collimator and projector help realign the internal optical axis, preventing soft edges (sharpness vignetting) and ensuring that the T-stops perform as the manufacturer designed.
Do you accept large, heavy briefcases from national production companies?
Of course. We have coverage and agreements with insured courier services prepared to collect, load and return complete sets or high-sensitivity optical equipment from anywhere in mainland Spain.
