Expert repair and calibration for Fujinon, Canon, and all major broadcast lenses. Serving TV stations, film studios, and production houses across the USA — with fast turnaround and a warranty on every job.
When a broadcast lens fails on set, every minute costs money. Our technicians specialise in broadcast lens repair, ENG lens repair, cine lens repair, and precision camera lens calibration — covering Canon, Fujinon, Sony, Angenieux, Zeiss, and more. We work with television stations, independent broadcasters, rental houses, film studios, and production companies nationwide.
Every lens that arrives in our facility is assessed in a HEPA-filtered clean-room, repaired using manufacturer-grade tooling and lubricants, then optically calibrated and performance-tested before it leaves. We stand behind every job with a written warranty.
From a back focus drift on a live studio lens to full mechanical overhaul of a field ENG lens, our technicians handle the complete range of broadcast, cine, and professional lens repair and calibration services.
Full teardown, clean, lubrication, optical alignment, and back-focus calibration for studio zoom and field broadcast lenses. We restore lenses that have suffered impact, moisture, dust, or mechanical wear.
Electronic News Gathering lenses take brutal punishment on location. We service ENG and EFP lenses from Canon and Fujinon, restoring focus, zoom tracking, iris control, and servo performance.
Precision service for cinema prime and zoom lenses — including full CLA (clean, lube, adjust), helicoid restoration, aperture blade service, optical alignment, and MTF testing across the focal range.
Front and back focus calibration, flange focal distance adjustment, zoom tracking, and optical collimation — tested using manufacturer-specified equipment to ensure peak sharpness across all focal lengths.
Camera body repair and servicing for broadcast-grade cameras — sensor cleaning, viewfinder issues, mount wear, and full system alignment with lens back-focus calibration as a package.
Dedicated Fujinon ENG, EFP, and EC-series lens repair — including servo motor replacement, demand unit calibration, zoom and focus tracking alignment, and exterior restoration.
Full-service repair for Canon’s range of broadcast and ENG lenses. We handle focus ring repair, zoom mechanism service, Image Stabilizer faults, and precision back focus adjustment.
Zoom demand unit service and repair for broadcast lenses — covering potentiometer wear, motor failure, cable and connector faults, and electronic recalibration of demand response curves.
Back focus (flange focal distance) drift is one of the most common issues in broadcast lenses. We perform precise back focus adjustment and collimation to restore accurate focus at the sensor plane.

Yes. Fujinon and Canon are our primary broadcast lens brands. We service the full ENG, EFP, and EC-series Fujinon range as well as Canon's broadcast and cine servo lenses. We also service Sony, Angenieux, Zeiss, Cooke, and Sigma lenses.
Back focus (flange focal distance) is the precise distance from the lens mount to the sensor/imager plane. When this drifts — from impact, wear, or a mount change — your lens will appear soft, especially at long focal lengths. Back focus calibration corrects this and is one of the most common broadcast lens repairs we perform.
Yes. We service and repair broadcast zoom demand controllers, including potentiometer replacement, servo motor repair, cable/connector faults, and electronic recalibration of demand response curves for smooth, repeatable zoom operation.
Yes. We accept mail-in lens repairs from TV stations, film studios, production houses, churches, and independent broadcasters across the United States. We can provide a prepaid shipping label and detailed packaging instructions to ensure your lens arrives safely.
All repairs come with a 6-month written warranty covering the specific fault repaired. Each lens is returned with a full written service report documenting the work completed and post-repair test results.
Yes. We specialise in restoring broadcast and ENG lenses damaged by salt water, sand, moisture, dust, and fungal or mould contamination. All cleaning is performed in our HEPA-filtered clean room to prevent recontamination during assembly.
We offer back focus calibration, zoom tracking alignment, optical collimation, flange focal distance adjustment, iris linearity calibration, and full MTF/sharpness testing — using manufacturer-specified test equipment and targets.
